    Description / Table of Contents: IOP Publishing presents Volume 6 of the open-access IOP Conference Series: Earth and Environmental Science (EES) as the online abstract book for the IARU International Scientific Congress on Climate Change: Global Risks, Challenges and Decisions (10–12 March, Copenhagen, Denmark). This abstracts-only volume of EES is quite different to standard IOP Conference Series proceedings volumes which contain full, peer-reviewed proceedings papers. This unique volume of more than 1400 abstracts, divided into 58 different sessions, contains all the oral and poster presentations from the Congress. In view of the importance of the Climate Change Congress as a scientific basis for the COP15 conference, we are delighted to offer this collection as a permanent record of current research devoted to climate change. We hope this compilation will contribute to future world-wide dialogue on climate change in the ongoing search to address the scientific, political, social and economic challenges ahead.

    Description / Table of Contents: The Beyond Kyoto conference in Aarhus March 2009 was organised in collaboration with other knowledge institutions, businesses and authorities. It brought together leading scientists, policy-makers, authorities, intergovernmental organisations, NGO's, business stakeholders and business organisations. The conference was a joint interdisciplinary project involving many academic areas and disciplines. These conference proceedings are organised in central and recurring themes that cut across many debates on climate change, the climatic challenges as well as the solutions. In the front there is a short presentation of the conference concept. Part I of the proceedings focuses on issues related to the society – covering climate policy, law, market based instruments, financial structure, behaviour and consumption, public participation, media communication and response from indigenous peoples etc. Part II of the proceedings concerns the scientific knowledge base on climate related issues – covering climate change processes per se, the potential impacts of projected climate change on biodiversity and adaptation possibilities, the interplay between climate, agriculture and biodiversity, emissions, agricultural systems, increasing pressure on the functioning of agriculture and natural areas, vulnerability to extreme weather events and risks in respect to sea-level rise etc...

    Description / Table of Contents: Reconstructing past climate and past ocean circulation demands the highest possible precision and accuracy which urges the scientific community to look at different sediment records such as the ones from coastal zones to deep-sea with a more complete set of technical and methodological tools. However, the information given by each tool varies in precision, accuracy and in significance according to their environmental settings. It is therefore essential to compare tools. With that in mind, and as part of the International year of Planet Earth, a workshop entitled `From deep-sea to coastal zones: Methods and Techniques for studying palaeoenvironments' took place in Faro (Portugal), from 25–29 February 2008 in order to: present several methods and techniques that can be used for studying sediments from deep-sea to coastal zones, namely for reconstructing palaeoenvironments in order to document past climatic changes and short to long-term environmental processes; allow cross experience between different fields and specialties, either from deep-sea to coastal zones or from micropaleontology to geochemistry; give the opportunity to students from different universities and countries to attend the workshop; publish a special volume on the presented methods and techniques during the workshop. The workshop was organized in four non-parallel sessions dealing with the use of micropaleontology, isotopes, biogeochemistry and sedimentology, as tools for palaeoenvironmental studies. The present IOP Conference Series: Earth and Environmental Science proceedings reflect this organization and papers are published in each theme. The papers are either short reviews or case studies and are highlighted below. The remains of microorganisms found in sediments are the main proxies used in micropaleontological studies. However, the link between fossilized remains and their living origin is not easy to reconstruct only based on the geologic/sedimentary record. Accordingly, Barbosa presents a review of the actual knowledge of living phytoplankton dynamics and the processes, or environmental conditions, which could contribute to the production of fossilized biogenic remains. In the next paper, de Vernal presents a review, based on several case studies, on how palynological fossils observed in sediments are used in tracing biogenic fluxes, characterizing sedimentary environments, or even reconstructing hydrographical conditions and productivity. The two other papers presented in the micropaleontological proxy section are case studies on the use of dinoflagellates (Rochon) and calcareous plankton remains (Guerreiro et al), respectively, to better understand their local or regional environmental living characteristics ant therefore their specific interpretation for palaeoenvironmental reconstruction at a regional scale. Isotopic proxies can be used either as provenance tracers or as chronometers of different processes. Once again, each study can provide a very specific framework of the proxies' use and it is very important to know and evaluate the limits of these tools in each environment and/or type of analyzed material. Accordingly, the two first articles deal with the study of organic carbon either by carbon and oxygen stable isotopes (Hélie) or by radiocarbon (Mollhenhauer and Rethemeyer) analysis. The two other articles in this section deal with the use of radioisotopes. Ghaleb reviews the methods for measuring short-lived radiosisotopes in sediments, giving examples of their use for estimating recent sedimentary accumulation rates; whereas Hillaire-Marcel reviews the potential use of U-series isotopes as radiochronometers in biogenic carbonates. Geochemistry groups more than one field of expertise. However, in the present section, inorganic geochemistry is not treated and both articles present work on a very specific, and at the same time very complex, compound of the organic matter realm: black carbon. As such, Veilleux et al present a density fractionation method for isolating the small quantities of soot-like and graphitic material usually found in natural samples, whereas González-Vila et al. illustrate the potential of the combined use of analytical pyrolysis and solid state 13C NMR to determine the presence of black carbon and to characterize the refractory organic matter in marine sediments from the Gulf of Cadiz (Spain). In the last section, two papers are presented and discuss sedimentological proxies. In their paper, using diffuse spectral reflectance data, Veiga-Pires and Mestre try to determine if `twinned cores' (or paired cores) can be used as duplicate records to increase the volume of sediments collected in the field, whereas Drago et al discuss the use of fish remains in sediments for the reconstruction of paleoproductivity. Each of the above papers benefited from the constructive comments of at least two reviewers and we wish to sincerely thank the reviewers for their timely evaluation. We also thank the participants, volunteers and organizers of the workshop for their implication, making this first workshop on Methods and Techniques for studying palaeoenvironments (METECH) a success. The workshop and this proceeding would not have been possible without the financial and logistical support of GEOTOP, CIMA, the Portuguese Foundation for Science and Technology (FACC07/1/1315) and IOP Conference Series: Earth and Environmental Science...

    Description / Table of Contents: This volume of IOP Conference Series: Earth and Environmental Science presents a selection of papers that were given at the WMO/GEO Expert Meeting on an International Sand and Dust Storm Warning System hosted by the Barcelona Supercomputing Center – Centro Nacional de Supercomputación in Barcelona (Spain) on 7-9 November 2007 (http://www.bsc.es/wmo). A sand and dust storm (SDS) is a meteorological phenomenon common in arid and semi-arid regions and arises when a gust front passes or when the wind force exceeds the threshold value where loose sand and dust are removed from the dry surface. After aeolian uptake, SDS reduce visibility to a few meters in and near source regions, and dust plumes are transported over distances as long as thousands of kilometres. Aeolian dust is unique among aerosol phenomena: (1) with the possible exception of sea-salt aerosol, it is globally the most abundant of all aerosol species, (2) it appears as the dominating component of atmospheric aerosol over large areas of the Earth, (3) it represents a serious hazard for life, health, property, environment and economy (occasionally reaching the grade of disaster or catastrophic event) and (4) its influence, impacts, complex interactions and feedbacks within the Earth System span a wide range of spatial and temporal scales. From a political and societal point of view, the concern for SDS and the need for international cooperation were reflected after a survey conducted in 2005 by the World Meteorological Organization (WMO) in which more than forty WMO Member countries expressed their interest for creating or improving capacities for SDS warning advisory and assessment. In this context, recent major advances in research – including, for example, the development and implementation of advanced observing systems, the theoretical understanding of the mechanisms responsible for sand and dust storm generation and the development of global and regional dust models – represent the basis for developing applications focusing on societal benefit and risk reduction. However, at present there are interdisciplinary research challenges to overwhelm current uncertainties in order to reach full potential. Furthermore, the community of practice for SDS observations, forecasts and analyses is mainly scientifically based and rather disconnected from potential users. This requires the development of interfaces with operational communities at international and national levels, strongly focusing on the needs of people and factors at risk ... The general objective of the WMO/GEO Expert Meeting on an International Sand and Dust Storm Warning System was to discuss and recommend actions needed to develop a global routine SDS-WAS based on integrating numerical SDS prediction and observing systems, and on establishing effective cooperation between data producers and user communities in order to provide SDS-WAS products capable of contributing to the reduction of risks from SDS. The specific objectives were: to identify, present and suggest future real-time observations for forecast verification and dust surveillance: satellite, ground-based remote sensing (passive and active) and in-situ monitoring; to present ongoing forecasting activities; to discuss and identify user needs: health, air quality, air transport operations, ocean, and others; to identify and discuss dust research issues relevant for operational forecast applications; to present the concept of SDS-WAS and Regional Centers...

    Description / Table of Contents: The Devonian was a critical period with respect to the diversification of early terrestrial ecosystems. The geotectonic setting was characterized by the switch from the post-Caledonian to the pre-Variscan situation. Plant life on land evolved from tiny tracheophytes to trees of considerable size in combination with a global increase in terrestrial biomass, and vertebrates started to conquer the land. Extensive shallow-marine areas and continental lowlands with a wide range of different habitats existed. These are preserved in a large number of basins all around the world. Climate change finally led from greenhouse to icehouse conditions towards the end of the Devonian. Rapid evolution of terrestrial ecosystems and climate change had a pronounced influence on sedimentation and biodiversity, not only in the terrestrial, but also in the marine realm. This volume contains case studies from Australia, China, Europe, South America and North America, and individual palaeoecosystems and their components have been investigated in different palaeogeographic settings that contribute to a much better understanding of the Devonian Period. This is a contribution to the IGCP 499 project on "Devonian land-sea interaction: evolution of ecosystems and climate".

    Description / Table of Contents: For thousands of years, religious ideas have shaped the thoughts and actions of human beings. Many of the early geological concepts were initially developed within this context. The long-standing relationship between geology and religious thought, which has been sometimes indifferent, sometimes fruitful and sometimes full of conflict, is discussed from a historical point of view. This relationship continues into the present. Although Christian fundamentalists attack evolution and related palaeontological findings as well as the geological evidence for the age of the Earth, mainstream theologians strive for a fruitful dialogue between science and religion. Much of what is written and discussed today can only be understood within the historical perspective. This book considers the development of geology from mythological approaches towards the European Enlightenment, biblical or geological Flood and the age of the Earth, geology within ‘religious’ organizations, biographical case studies of geological clerics and religious geologists, religion and evolution, and historical aspects of creationism and its motives.

    London : The Geological Society
    Description / Table of Contents: This book presents a collection of papers that combines marine and terrestrial geological investigations valuable to hazard assessment in rocky coastal areas, including examples mostly coming from the Italian coasts. The hazardous processes that are discussed include: large slope failures, cliff recession and floods of steep coastal streams. It is assumed that coastal slopes operate as transfer zones of land-born geological processes, which deliver sediment to the coastal and open sea at intermittent time intervals, and therefore place coastal communities that are exposed or vulnerable to these events at high risk. Rocky coastal areas can be associated with regions of active or recent tectonics/volcanic activity, or can develop as low-relief cliffs along non-active margins. In all these settings, mass-wasting phenomena represent the most serious hazardous processes, and there is a need to characterize and model the factors causing them. It is stressed that proper comprehension of coastal mass-wasting hazard has to include shipboard acoustic surveys, historical source investigations and onshore geological features.

    Description / Table of Contents: Periglacial and paraglacial environments, located outside ice sheet margins but responding to similar climate forcings, are key to identifying climate change effects upon the Earth system. These environments are relicts of cold Earth processes and so are most sensitive to global warming. Changes in the distribution and thickness of permafrost in continental interiors have implications for ecosystem and landscape stability. Periglacial Alpine environments are experiencing increased rockfall and mass movement, leading to rock glacier instability and sediment release to downstream rivers. In turn, these landscape effects impact on natural hazards and human activities in these sensitive and geologically transient environments. Papers in this volume explore some of these interrelated issues in field studies from Europe, North America and Asia. The volume will be of interest to geomorphologists, modellers, environmental managers, planners and engineers working on landscape, climate and environmental change in periglacial and paraglacial areas.

    Description / Table of Contents: Accretionary orogens form at convergent plate boundaries and include the supra-subduction zone forearc, magmatic arc and backarc components. They can be broken into retreating and advancing types, based on their kinematic framework and resulting geological character. Accretionary systems have been active throughout Earth history, extending back until at least 3.2 Ga, and provide an important constraint on the initiation of horizontal motion of lithospheric plates on Earth. Accretionary orogens have been responsible for major growth of the continental lithosphere, through the addition of juvenile magmatic products, but are also major sites of consumption and reworking of continental crust through time. The aim of this volume is to provide a better understanding of accretionary processes and their role in the formation and evolution of the continental crust. Fourteen papers deal with general aspects of accretion and metamorphism and discuss examples of accretionary orogens and crustal growth through Earth history, from the Archaean to the Cenozoic.

    Description / Table of Contents: Founded in 1807, the Geological Society of London became the world's first learned society devoted to the Earth sciences. In celebration of the Society's 200-year history, this book commemorates the lives of the Society's 13 founders and sets geology in its national and European context at the turn of the nineteenth century. In Britain, geology was emerging as a subject in its own right from three closely related disciplines - chemistry, mineralogy and medicine - disciplines that reflect the principal professions and interests of the founders. The tremendous energy and cooperation of these 13 men, about whom little was previously known, quickly mobilized like-minded men around the country and fuelled the nation's passion for geology; an enthusiasm that soon spread to America and Australia. Two previously unpublished works from this period, essential to understanding the founding of the Society, are reproduced here for the first time. The book closes with a review of the Society's 2007 Bicentenary celebrations.

    Description / Table of Contents: There is much interest in gas hydrates in relation to their potential role as an important driver for climate change and as a major new energy source; however, many questions remain, not least the size of the global hydrate budget. Much of the current uncertainty centres on how hydrates are physically stored in sediments at a range of scales. This volume details advances in our understanding of sediment-hosted hydrates, and contains papers covering a range of studies of real and artificial sediments containing both methane hydrates and CO2 hydrates. The papers include an examination of the techniques used to locate, sample and characterize hydrates from natural, methane-rich systems, so as to understand them better. Other contributions consider the nature and stability of synthetic hydrates formed in the laboratory, which in turn improve our ability to make accurate predictive models.

    Description / Table of Contents: The chapters in this volume represent an extensive review of the material presented by the invited speakers at a short course on Thermodynamics and Kinetics of Water-Rock Interaction held prior to the 19th annual V. M. Goldschmidt Conference in Davos, Switzerland (June 19-21, 2009). This volume stems from a convergence of a number of factors. First, there is a compelling societal need to resuscitate the field of the thermodynamics and kinetics of natural processes. This field is essential to quantify and predict the response of the Earth’s surface and crust to the disequilibria caused by the various natural and anthropic inputs of energy to our planet. As such, it serves as the basis for sustainable development and assuring the quality of life on the Earth; it serves as the key to understanding the long term future of radioactive waste storage, toxic metal mobility in the environment, the fate of CO2 injected into the subsurface as part of carbon sequestration efforts, quantifying the quality of petroleum reservoirs and generating novel methods of petroleum extraction, and the identification of new ore deposits. The recent interest in the weathering of continental surfaces and its impact on global elemental cycles and climate evolution has also brought new attention to the thermodynamics and kinetics of water-rock interactions as it has become evident that only a true mechanistic approach based on robust thermodynamic and kinetic laws and parameters can accurately model these processes. Yet, this field has, in many ways, atrophied over the past two decades. Relatively few students have pursued graduate research in this field; many of the great contributors to this field have retired or otherwise moved on. No doubt some of this atrophy was caused by economic factors. For roughly two decades from the mid-1980’s to the mid-2000’s the price of base metals and petroleum, when adjusted for inflation, were at lows not seen for over a generation. Some of this atrophy was also caused by past successes in this field; the development and success of computer generated thermodynamic databases, for example, giving the illusion that the work of scientists in this field was complete. A second factor motivating the creation of this volume was that it was requested by our graduate students. We currently coordinate two European Research Networks: MIR and MIN-GRO, and participate in two others GRASP and DELTA-MIN. As part of these networks we ran summer schools on the thermodynamics and kinetics of water-rock interaction in La Palma, Spain and in Anglet, France. In total theses classes were attended by roughly 100 students. By the end of these schools, we received numerous demands from our students requesting a book to help them follow the subject, as they, like most when introduced to thermodynamics and kinetics, got rapidly lost among the equations, symbols, and conventions, and standard states. This volume is an attempt to help these and others through these formalities towards applying the many advances available in thermodynamics and kinetics towards solving academic and societal problems. A third factor is that we felt this volume would be a great way of getting many of our friends to write up that review paper that we have been hoping they would write for years. The chapters in this volume represent our effort to do just this. We recall Dave Sherman first explaining to us how to perform first principle thermodynamics calculations at an European Research Conference in Crete, Greece during 1999. We recall that his explanations were so clear that we wished to have recorded it. Manolo Prieto gave in La Palma, Spain a lecture summarizing decades of research on the thermodynamics of solid solutions. This lecture opened up our eyes to how little we know about the chemistry of minor and trace elements, and how they can drastically alter the pathways of reactions in nature. He also made us aware of the thermodynamic formalism available for advancing our ability to quantify the behavior of these elements in complex natural systems. Another lecture we left knowing that we needed a permanent record of was that of Dmitrii Kulik on the thermodynamics of sorption in Jena, Germany. After leaving Dmitrii’s talk, we felt that we finally understood the differences between the various models used to describe sorption. Yet another chapter we felt essential to see published is a summary of the latest advances in mineral precipitation kinetics. We have followed the work of Bertrand Fritz for years as he developed a new formalism for quantifying mineral nucleation and growth, and in particular practical approaches to apply this formalism to complex systems. We are very pleased we were able to convince him to contribute his chapter to this volume. Other chapters we believed were essential to include was that of Andrew Putnis, who has gathered extensive evidence for the existence of mineral transformation reactions, a novel and widespread mechanism in nature. Through this volume we were able to get Andrew to bring all this evidence together in a single place, where we can see clearly the significance and pervasiveness of these reactions. Similarly Jichwar Ganor has, over the past two decades, gathered a variety of evidence showing how organic compounds affect both thermodynamics and kinetics. Jichwar’s chapter brings all this evidence together in one place for the first time. This volume is completed with the future of this field, the application of thermodynamics and kinetics to natural phenomena. Two of the leaders in the development and application of reactive transport modeling are Carl Steefel and Chen Zhu. Carl, who has written what may be the most advanced reactive transport modeling code currently available, together with Kate Malher has written an informative summary of recent advances in reactive transport modeling. Chen then shows how the use of these models provides insight into the relative role of dissolution and precipitation kinetics in natural processes. This volume finishes with insightful applications of reactive transport modeling together with field observations to understand chemical weathering from the centimeter to the regional scale by Susan Brantley, Art White and Yves Goddéris.

    Description / Table of Contents: Concern exists over human-generated increases in atmospheric greenhouse gases and their potential consequences to society. The Intergovernmental Panel on Climate Change (IPCC) in 2007 finds that global temperatures have increased by 0.8ºC since 1850 and that climate warming is now ’unequivocal’. While the human imprint is becoming increasingly apparent, Earth’s climate has shifted dramatically and frequently during the last few million years, alternating between ice ages, when vast glaciers covered Northern Europe and much of North America, and interglacials—warm periods much like today. Farther back in geologic time, climates have differed even more from the present. Thus, to fully understand the unusual changes of the 20th century and possible future trends, these must be placed in a longer-term context extending beyond the period of instrumental records. The Encyclopedia of Paleoclimatology and Ancient Environments, a companion volume to the recently-published Encyclopedia of World Climatology, provides the reader with an entry point to the rapidly expanding field of paleoclimatology—the study of climates of the past. Highly interdisciplinary in nature, paleoclimatology integrates information from a broad array of disciplines in the geosciences, ranging from stratigraphy, geomorphology, glaciology, paleoecology, paleobotany to geochemistry and geophysics, among others. The encyclopedia offers 230 informative articles written by over 200 well known international experts on numerous subjects, ranging from classical geological evidence to the latest research. The volume is abundantly illustrated with line-drawings, black-white and color photographs. Articles are arranged alphabetically, with extensive bibliographies and cross-references.

    Description / Table of Contents: The Palaeoproterozoic era (2500–1600 Ma) was a critical period of Earth history, with dynamic evolution from the deep planetary interior to its surface environment. Several lines of geological evidence suggest the existence of at least one pre-Rodinia supercontinent, named Nuna or Columbia, which formed near the end of Palaeoproterozoic time. Prior to this assembly, there may have been an older supercontinent (Kenorland) or perhaps only independently drifting supercratons. The tectonic records of amalgamation and dispersal of these ancient landmasses provide a framework that links processes of the deep Earth with those of its fluid envelope. The sixteen papers in this volume present reviews and new analytical data that span the geological record of Palaeoproterozoic Earth and provide a current picture of Palaeoproterozoic research. The volume provides a useful reference book for students and professional geoscientists interested in this important period of global evolution.

    Description / Table of Contents: Following the late Neoproterozoic – early Cambrian breakup of the supercontinent Rodinia, Gondwana evolved as one of the principal continental masses on Earth, embracing most of South America, Africa, Australasia, Antarctica, much of western Europe and parts of Asia. Around its margins were various other terranes that had varying tectonic and biogeographical affinities with the main continental block. This book incorporates a series of reviews and multidisciplinary research papers that together explore the tectonic, palaeogeographical and palaeobiogeographical evolution of the elements that made up the peri-Gondwanan collage. The stratigraphical scope of the coverage embraces the late Precambrian through early Devonian, providing a comprehensive overview of structural, stratigraphical and biological evolution through this significant interval of Earth history. Integration of these various processes throughout the volume will be of broad-based interest to a wide range of geoscientists.

    Keywords: speleogenesis ; cave origin ; karst ; artesian ; hypogene speleogenesis ; gypsum karst
    Description / Table of Contents: In this book geological the conditions of speleogenesis in the Miocene gypsum in the Western Ukraine are characterized, particularly the role of lithological and structural prerequisites in speleogenesis. The special attention is given to structural and textural unhomogeneities in the gypsum stratum and to their role in the formation of fractures. Fracture systems in the gypsum and the structure of the unique maze cave systems are examined in details. It is shown that speleo-initiating fractures in the gypsum strata belong to the lithogenetic type and form largely independent multi-storey networks, with each storey being confined within a certain vertical structural/textural zone (unit) of the stratum. This determines the multi-storey structure of the caves in the region. Two problems related to structural and textural characteristics of the gypsum stratum are discussed in details: the formation of giant dome structures by way of gypsum recrystallization during the synsedimentary and early diagenesis stages, and the genesis of fractures. Speleogenetic realization of the existing structural prerequisites occurred under conditions of a confined multi-storey artesian aquifer system due to an upward flow across the gypsum from the under-gypsum aquifer.

    Keywords: mechanical properties of rocks ; natural hazards ; rock deformation and creep ; rock failure ; rock physics ; transport properties of rocks
    Description / Table of Contents: Natural hazards events such as earthquakes or volcanic eruptions involve activation of coupled thermo-hydro-chemo-mechanical processes in rocks. The present book assembles unpublished contributions to the 7th Euro-Conference on Rock Physics and Geomechanics, held in 2007 in Erice, Italy. It presents new laboratory data, theoretical and numerical rock physics models and field observations relevant to the study of natural hazards. In particular, several papers are devoted to rock failure and explore the relationship between the competing deformation micro-mechanisms. Several others investigate shear-induced anisotropy of mechanical and/or transport properties, both in large-scale geologic objects and in laboratory samples. The remaining papers treat various aspects of rock physics and their industrial applications such as geothermics and reservoir characterization.

    Description / Table of Contents: Given the tremendous toll in human lives and attendant economic losses, it is appropriate that scientists are working hard to understand better earthquakes, with the aim of forecasting and, ultimately, predicting them. In the last decades increasing attention has been paid to the coseismic effects on the natural environment, creating a solid base of empirical data for the estimation of source parameters of strong earthquakes based on geological observations. The recently introduced INQUA scale (Environmental Seismic Intensity–ESI 2007 Scale) of macroseismic intensity clearly shows how the systematic study of earthquake surface faulting, coseismic liquefaction, tsunami deposits and other primary and secondary ground effects can be integrated with ‘traditional’ seismological and tectonic information to provide a better understanding of the seismicity level of an area and the associated hazards. At the moment this is the only scientific means of equating the seismic records to the seismic cycle time-spans extending the seismic catalogues even to tens of thousands of years, improving future seismic hazard analyses. This Special Publication covers some of the latest multidisciplinary work undertaken to achieve that aim. Eighteen papers from research groups from all continents address a wide range of topics related both to palaeoseismological studies and assessment of macroseismic intensity based only on the natural phenomena associated with an earthquake.

    Description / Table of Contents: Non-marine Late Palaeozoic and Mesozoic formations are widespread in mainland SE Asia. Although the first reports on fossils from some of these formations were published as early as the 1890s, it is only since 1980 that floras and faunas from the Permian, Triassic, Jurassic and Cretaceous of SE Asia have received the attention they deserve. Fieldwork in various parts of Thailand and Laos has revealed a succession of fossil assemblages that now allows a reconstruction of the evolution of continental ecosystems in that part of the world during the Late Palaeozoic and the Mesozoic. The first papers in this book present the geological background of these floral and faunal successions, as well as historical aspects of their discovery. Descriptions of new taxa and review papers deal with plants, sharks, bony fishes, turtles, crocodilians, dinosaurs and mammal-like reptiles. Papers about the Mesozoic palaeobiogeography, environments and climates of Asia conclude the volume.

    Description / Table of Contents: This book considers the geology between North and South America. It contributes to debate about the area's evolution, particularly that of the Caribbean. Prevailing understanding is that the Caribbean formed in the Pacific and was engulfed between the Americas as the latter drifted west. Accordingly, the Caribbean Plate comprises internal, Jurassic–Cretaceous oceanic rocks, thickened into a Cretaceous hotspot/plume plateau, with obducted ophiolites and Cretaceous–Palaeogene, subduction-related, intra-oceanic volcanic arc and metamorphosed arc/continental rocks exposed on its margins. An alternative interpretation is that the Caribbean evolved in place. It consists largely of continental crust, extended in the Triassic–Jurassic, which subsided below thick Jurassic–Cretaceous carbonate rocks and flood basalts, and Cenozoic carbonate and clastic rocks. After uplift of ‘oceanic’ and volcanic arc rocks onto (continental) margins, the interior foundered in the Middle Eocene. Papers range from regional overviews and discussions of Caribbean origins to aspects of local geology arranged in a circum-Caribbean tour and ending in the interior. They address tectonics, structure, geochronology, seismicity, igneous and metamorphic petrology, metamorphism, geochemistry, stratigraphy and palaeontology.

    Description / Table of Contents: Thermochronology - the use of temperature-sensitive radiometric dating methods to reconstruct the thermal histories of rocks - has proved to be an important means of constraining a wide variety of geological processes. Fission track and (U–Th)/He analyses of apatites, zircons and titanites are the best-established and most sensitive methods for reconstructing such histories in the uppermost kilometres of the crust, over time scales of millions to hundreds of millions of years. The papers published in this volume are divided into two sections. The first section on ‘New approaches in thermochronology’, presents the most recent advances of existing thermochronological methods and demonstrates the progress in the development of alternative thermochronometers and modelling techniques. The second section, ‘Applied thermochronology’, comprises original papers about denudation, long-term landscape evolution and detrital sources from the European Alps, northwestern Spain, the Ardennes, the Bohemian Massif, Fennoscandia and Corsica. It also includes case studies from the Siberian Altai, Mozambique, South Africa and Dronning Maud Land (East Antarctica) and reports an ancient thermal anomaly within a regional fault in Japan.

    Keywords: soil ; pedology ; Northern Circumpolar Region
    Description / Table of Contents: In a clear style, the atlas describes the origin and major characteristics of the different soil types that can be found in this environment. The atlas discusses the possible impacts of climate change on permafrost-affected soils and explains the critical role that they play in the global climate and global carbon cycles. 6. For the first time ever, the distribution of soil types for the entire northern circumpolar region can be visualised in a comprehensible manner by the lay-person. Information on the major soil types is presented in detail on twenty six map plates (the atlas has an A3 page size giving a dramatic A2 spread for maps). In a novel exercise, the World Reference Base for Soil Resources has been used as a framework for correlating knowledge from diverse national soil classification systems into a single, coherent, inter-continental product. The atlas illustrates the diversity of soil in the permafrost and seasonally frozen environments through a series of maps supported by explanatory and easily readable texts, high quality photographs and descriptive graphics. The atlas presents the reader with a series of maps that show the variation of soil properties in a circumpolar context and from a polar perspective, allowing comparisons to be made across international boundaries. In addition, larger scale maps show the distribution of major soil types by regions with descriptions of the major issues. The maps have been produced through the elaboration of harmonized soil databases for the northern circumpolar areas by Geographic Information Systems software (GIS).Through supporting texts, the atlas describes the major soil types found in northern latitudes, together with their principal properties and characteristics, the main soil forming processes, the importance of soil classification and the use of soil. Special attention is given to impact of cold climates on soil characteristics and on the relationship between climate change and soils properties (e.g. carbon dynamics, carbon sinks and sources, methane emission). In addition, the atlas illustrates how soil can be used as indicators of past climate change and present examples local and regional perspectives of the importance and functions of soil for society as a whole and particularly for indigenous northern cultures.

    Keywords: earthquake
    Description / Table of Contents: In recent years, large earthquakes in the circum-Pacific region have repeatedly demonstrated its particular vulnerability to this potentially devastating natural hazard, including the M ~ 9.2 Northern Sumatra earthquake and tsunami of 2004 which resulted in the deaths of nearly 300,000 people. In the late-1990s, major advancements in seismic research greatly added to the understanding of earthquake fault systems, as large quantities of new and extensive remote sensing data sets, that provided information on the solid earth on scales previously inaccessible, were integrated with a combination of innovative analysis techniques and advanced numerical and computational methods implemented on high-performance computers. This book includes a variety of studies that focus on the modeling of tsunamis and earthquakes, both large-scale simulation and visualization programs, as well as detailed models of small-scale features. Particular attention is paid to computational techniques, languages, and hardware that can be used to facilitate data analysis, visualization, and modeling. Also included are studies of several earthquake forecasting techniques and associated comparisons of their results with historic earthquake data. Finally, the volume ends with theoretical analyses of statistical properties of seismicity by internationally recognized experts in the field. This volume will be of particular interest to researchers interested in the multiscale simulation and visualization of large earthquakes and tsunamis.

    Description / Table of Contents: Volcanoes become active when fluids are in motion, and erupt when these fluids escape into the atmosphere. Volcanic fluids are a mixture of solid, liquid and gas. These mixtures result in a complex range of flow behaviour, especially during interaction with conduit geometry. These processes are not directly observable and must be inferred from interpretations of field observation and measurement. One of the outcomes of this complexity is the generation of pressure and force transients as high-density phases accelerate and decelerate during unsteady flow. These transients are one means of flexing the conduit wall, a process that manifests itself as ground motion and is detectable as volcano seismic signals. On eruption, volcanic fluids interact with the atmosphere and generate acoustic and thermal signals. In this Special Publication we present a series of papers based on field, numerical and experimental approaches that seek to establish links between geophysical signals and fluid motion in volcanic conduits.

    Description / Table of Contents: Magmas are subject to a series of processes that lead to their differentiation during transfer through, and storage within, the Earth's crust. The depths and mechanisms of differentiation, the crustal contribution to magma generation through wall-rock assimilation, the rates and timescales of magma generation, transfer and storage, and how these link to the thermal state of the crust are subject to vivid debate and controversy. This volume presents a collection of research articles that provide a balanced overview of the diverse approaches available to elucidate these topics, and includes both theoretical models and case studies. By integrating petrological, geochemical and geophysical approaches, it offers new insights to the subject of magmatic processes operating within the Earth's crust, and reveals important links between subsurface processes and volcanism.

    Description / Table of Contents: This book is the first to describe the history of geoconservation. It draws on experience from the UK, Europe and further afield, to explore topics including: what is geoconservation; where, when and how did it start; who was responsible; and how has it differed across the world? Geological and geomorphological features, processes, sites and specimens, provide a resource of immense scientific and educational importance. They also form the foundation for the varied and spectacular landscapes that help define national and local identity as well as many of the great tourism destinations. Mankind's activities, including contributing to enhanced climate change, pose many threats to this resource: the importance of safeguarding and managing it for future generations is now widely accepted as part of sustainable development. Geoconservation is an established and growing activity across the world, with more participants and a greater profile than ever before. This volume highlights a history of challenges, set-backs, successes and visionary individuals and provides a sound basis for taking geoconservation into the future.

    Description / Table of Contents: The morphology of Earth's surface reflects the interaction of climate, tectonics and denudational processes operating over a wide range of spatial and temporal scales. These processes can be considered catastrophic or continuous; depending on the timescale of observation or interest. Recent research had required integration of historically distinct subjects such as geomorphology, sedimentology, climatology and tectonics. Together, these have provided new insights into absolute and relative rates of denudation, and the factors that control the many dynamic processes involved. Specific subject areas covered are sediment transport processes and the timescales of competing processes, the role of the geological record and landscapes in constraining different processes, the nature of landscape evolution at different spatial scales and in contrasting geological environments.

    Description / Table of Contents: This volume, in honour of Peter L. Forey, is about fishes as palaeobiogeographic indicators in the Mesozoic and Cenozoic. The last 250 million years in the history of Earth have witnessed the break-up of Pangaea, affecting the biogeography of organisms. Fishes occupy almost all freshwater and marine environments, making them a good tool to assess palaeogeographic models. The volume begins with studies of Triassic chondrichthyans and lungfishes, with reflections on Triassic palaeogeography. Phylogeny and distribution of Late Jurassic neoselachians and basal teleosts are broached, and are followed by five papers about the Cretaceous, dealing with SE Asian sharks, South American ray-finned fishes and coelacanths, European characiforms, and global fish palaeogeography. Then six papers cover Tertiary subjects, such as bony tongues, eels, cypriniforms and coelacanths. There is generally a good fit between fish phylogenies and the evolution of the palaeogeographical pattern, although a few discrepancies question details of current palaeogeographic models and/or some aspects of fish phylogeny.

    Description / Table of Contents: Some 75 years after the visionary work of Wegener and du Toit, Neoproterozoic to Mesozoic geological correlations between South America and Africa are re-examined in the light of plate tectonics and modern geological investigation (structural and metamorphic studies, stratigraphic logging, geochemistry, geochronology and palaeomagnetism). The book presents both reviews and new research relating to the shared Gondwana origins of countries facing each other across the South Atlantic Ocean, especially Brazil, Argentina, Cameroon, Nigeria, Angola, Namibia and South Africa. This is the first comprehensive treatment to be readily available in book form. It covers the common elements of cratonic areas pre-dating Gondwana, and how they came together in late Precambrian and Cambrian times with the formation of the Pan-African/Brasiliano orogenic belts (Dom Feliciano, Brasília, Ribeira, Damara, Gariep, Kaoko, etc.). The subsequent shared Palaeozoic and Mesozoic sedimentary record (Karoo system) prior to Gondwana break-up is also reviewed.

    Description / Table of Contents: Minerals are intrinsically resistant to the processes that homogenize silicate liquids—their compositions thus yield an archive of volcanic and magmatic processes that are invisible at the whole rock scale. New experiments, and recent advances in micro-analytical techniques open a new realm of detail regarding the mineralogical record; this volume summarizes some of this progress. The alliance of the sub-fields reviewed in this volume bear upon fundamental issues of volcanology: At what depths are eruptions triggered, and over what time scales? Where and why do magmas coalesce before ascent? If magmas stagnate for thousands of years, what forces are responsible for initiating final ascent, or the degassing processes that accelerate upward motion? To the extent that we can answer these questions, we move towards formulating tests of mechanistic models of volcanic eruptions (e.g., Wilson, 1980; Slezin, 2003; Scandone et al., 2007), and hypotheses of the tectonic controls on magma transport (e.g., ten Brink and Brocher, 1987; Takada, 1994; Putirka and Busby, 2007). Our goal, in part, is to review how minerals can be used to understand volcanic systems and the processes that shape them; we also hope that this work will spur new and integrated studies of volcanic systems. Our review begins by tracing the origins of mineral grains, and methods to estimate pressures (P) and temperatures (T) of crystallization. Hammer shows how "dynamic" experiments (conducted with varying P or T) yield important insights into crystal growth. Chapters by Putirka, Anderson, and Blundy and Cashman review various igneous geothermometers and geobarometers and introduce new calibrations. Among these chapters are many familiar models involving olivine, amphibole, feldspar, pyroxene, and spinel. Blundy and Cashman introduce new methods based on phase equilibria, and in another chapter, Hansteen and Klügel review P estimation based on densities of entrapped fluids and appropriate equations of state. Rutherford's chapter returns to the issue of disequilibrium, with a review of methods to estimate magma ascent rates, and a summary of results. Our volume then moves to a review of melt inclusions. Kent shows how pre-mixed magma compositions can be preserved as inclusions, providing a window into pre-eruptive conditions. Métrich and Wallace review the volatile contents in basaltic melt inclusions and "magma degassing paths". Such methods rely upon vapor saturation pressures, which are derived from experimentally calibrated models. Chapters by Moore and Blundy and Cashman test two of the most important models, by Newman and Lowenstern (2002) (VolatileCalc) and Papale et al. (2006). Moore provides a guide to the appropriate use of these models, and their respective errors. The next four chapters document insights obtained from isotopic studies and diffusion profiles. Ramos and Tepley review developments of micro-analytical isotope measurements, which now have the potential to elucidate even the most cryptic of open system behaviors. Cooper and Reid examine the time scales for such processes through U-series age dating techniques, and Bindeman reviews oxygen isotopes and their uses as tracers of both magmas and crystals. Costa then reviews yet another means to estimate the rates of magmatic processes, using mineral diffusion profiles, with important implications for magma processing. In the next two chapters, Streck reviews an array of imaging methods and mineral textures, and their potential for disentangling mixed magmas, and Armienti takes a new look at the analysis of crystal size distributions (CSD), with applications to Mt. Etna. Our volume concludes with a chapter by Bachmann and Bergantz summarizing compositional zonations and a review of the thermal and compositional forces that drive open system behavior. Finally, descriptions of many of the most common analytical approaches are also reviewed within these chapters. Analytical topics include: secondary ion mass spectrometry (Blundy and Cashman; Kent); electron microprobe (Blundy and Cashman; Kent; Métrich and Wallace; laser ablation ICP-MS (Kent; Ramos and Tepley); Fourier transform infrared spectroscopy (Moore; Métrich and Wallace); microsampling and isotope mass spectrometry (Ramos and Tepley); U-series measurement techniques (Cooper and Reid); Nomarski differential interference contrasts (Streck); micro-Raman spectroscopy (Métrich and Wallace); back-scattered electron microscopy, and cathodoluminescence (Blundy and Cashman). As noted, our hope is that integrated studies can bring us closer to understanding how volcanic systems evolve and why eruptions occur. Our primary goal is to review how minerals can be used to understand volcanic systems; we also hope that this review might spur new and integrated studies of volcanic systems.

    Trondheim : NGU - Geological Survey of Norway
    Keywords: geology ; society ; Norway
    Description / Table of Contents: This volume of NGU Special Publication presents some of the ongoing research at the Geological Survey of Norway and shows how geology and geological knowledge influence many areas of society. The global demand for geological resources is on the rise, and knowing where to look for these resources is becoming increasingly more important. In addition, quantifying these resources is vital to ensure present-day as well as future supplies. As society and technology evolve (cf., the Stone Age-, Bronze Age-, Iron Ageprogression) so does the demand for geological resources. A sagacious assessment of geological resources therefore requires a broad, research-based approach.

    Description / Table of Contents: The 14th International Symposium for the Advancement of Boundary Layer Remote Sensing (ISARS 2008) addresses acoustical, optical and microwave techniques to probe the lower part of the atmosphere. The symposium focuses on the physical basis of remote sensing techniques and new instruments. A theme for the conference is also various applications of remote sensing, this year with special emphasis on wind energy. ISARS is an informal association of scientists from all over the world which organizes a symposium every second year. While the abbreviation ISARS has remained unchanged since the start in Calgary 1981, the words have changed from International Symposium on Acoustic Remote Sensing and Associated Techniques of the Atmosphere and Oceans because other techniques than the acoustic have become important for boundary layer remote sensing. Specifically lasers for remote wind sensing are developing rapidly. By the end of each symposium the chairman of the next has been elected. So far the symposia have taken place in different countries each time with different chairs. The scientific organizing committee, which consists mainly of chair persons of previous symposia, maintains the continuity of themes and of the organization in general. After the last symposium held in Garmisch-Partenkirchen, many of the papers appeared in revised and improved form in a special issue of Meteorologische Zeitschrift. A similar special issue is also planned to follow ISARS 2008. I wish to express my gratitude to the scientific organizing committee for valuable advice and to the local organizing committee for all their effort with the conference papers and the conference itself.

    Description / Table of Contents: Caldera-formation is one of the most awe-inspiring and powerful displays of nature's force. Resultant deposits may cover vast areas and significantly alter the immediate topography. Post-collapse activity may include resurgence, unrest, intra-caldera volcanism and potentially the start of a new magmatic cycle, perhaps eventually leading to renewed collapse. Since volcanoes and their eruptions are the surface manifestation of magmatic processes, calderas provide key insights into the generation and evolution of large-volume silicic magma bodies in the Earth's crust. Despite their potentially ferocious nature, calderas play a crucial role in modern society's life. Collapse calderas host essential economic deposits and supply power for many via the exploitation of geothermal reservoirs, and thus receive considerable scientific, economic and industrial attention. Calderas also attract millions of visitors world-wide with their spectacular scenic displays. To build on the outcomes of the 2005 calderas workshop in Tenerife (Spain) and to assess the most recent advances on caldera research, a follow-up meeting was proposed to be held in Mexico in 2008. This abstract volume presents contributions to the 2nd Calderas Workshop held at Hotel Misión La Muralla, Querétaro, Mexico, 19–25 October 2008. The title of the workshop `Reconstructing the evolution of collapse calderas: Magma storage, mobilisation and eruption' set the theme for five days of presentations and discussions, both at the venue as well as during visits to the surrounding calderas of Amealco, Amazcala and Huichapan. The multi-disciplinary workshop was attended by more than 40 scientist from North, Central and South America, Europe, Australia and Asia. Contributions covered five thematic topics: geology, geochemistry/petrology, structural analysis/modelling, geophysics, and hazards...

    Description / Table of Contents: The Hiroshi Wakita Volume II is a collection of original papers regarding the role of terrestrial fluids in earthquake and volcanic processes. The importance of monitoring volcanic gases for studying volcanic eruptions is widely recognized by the scientific community. On the other hand, the usefulness of hydrological and geochemical monitoring in earthquake studies, especially in earthquake prediction, has been controversial. This Pure and Applied Geophysics volume provides the results of recent studies on terrestrial fluids involved in both processes. The volume honors Hiroshi Wakita for his scientific contributions. It should be useful to researchers and graduate students in the field.

    Description / Table of Contents: This volume of the IOP Conference Series: Earth and Environmental Sciences presents a selection of papers given at the Donald D Harrington Symposium on the Geology of the Aegean held on the campus of the University of Texas at Austin on April 28-30, 2008. Donald D Harrington was born in Illinois in 1899 and moved westward after serving in the Army Air Corps during World War I. Mr Harrington took a position as a landman with Marlin Oil Company in Oklahoma. When the Texas Panhandle oil boom hit in 1926, he moved to Amarillo, Texas, where he met Sybil Buckingham—the granddaughter of one of Amarillo's founding families. They married in 1935 and went on to build one of the most successful independent oil and gas operations in Texas history. The couple created the Don and Sybil Harrington Foundation in 1951 to support worthy causes such as museums, medical research, education, and the arts. At the Harrington Symposium on the Geology of the Aegean, researchers presented papers organized under five general themes: (1) the geology of Aegean in general (2) the geologic history of specific domains within the Aegean (Cyclades, Menderes, Kazdag, Rhodope, Crete, southern Balkans, etc) (3) the dynamic tectonic processes that occur within the Aegean (4) its geo-archeological history, natural history and hazards and (5) comparisons of the Aegean to regions elsewhere (e.g., Basin and Ranges; Asian extensional terranes). The Aegean is a locus of dynamic research in a variety of fields, and the symposium provided an opportunity for geologists from a range of disciplines to interact and share new results and information about their research in the area...

    Description / Table of Contents: There are continual rounds of annual conferences, special sessions and other symposia that provide ample opportunity for researchers to convene and discuss igneous processes. However, the origins of laccoliths and sills continue to inspire and confound geologists. In one sense, this is surprising. After all, don't we know all we need to know about these rocks by now? As testified by the diverse range of topics covered in this volume, the answer is clearly ‘no’. This book contains contributions on physical geology, igneous petrology, volcanology, structural geology, crustal mechanics and geophysics that cover the entire gambit of geological processes associated with the shallow emplacement of magma. High-level intrusions in sedimentary basins can also act as hydrocarbon reservoirs and as sources for thermal maturation. In drawing together a diversity of perspectives on the emplacement of sills, laccoliths and dykes we hope to advance further our understanding of their behaviour.

    Description / Table of Contents: Increasingly, researchers have reported that passive margins do not show a simple uninterrupted thermal sag pattern of post-rift subsidence following continental separation. Rather, the structural and stratigraphic development of such margins may record evidence of complex phases of differential subsidence, exhumation and fold development. Some of the fold structures observed on passive continental margins appear to be related to regional stresses transmitted through basement rocks, whereas others are related to gravitational sliding and toe-thrusting. This special publication concentrates on the first of these categories. The morphology and distribution of such folds, together with potential mechanisms for generation of regional stress, are described in a series of papers by authorities in the field. As well as being an enigmatic feature of passive margin geology, the compressive folds have significance in the exploration for petroleum.

    Description / Table of Contents: Twenty years have passed since Menzies & Hawkesworth extended the concept of metasomatism to mantle processes. The aim of this book is to gather together progress made on this topic since then. Most of the 14 papers reported in the volume rely on in situ major and trace element analyses of minerals and glasses in mantle xenoliths, and deal with different kinds of metasomatic agents at variable fluid/rock ratios in tectonic settings as different as intra-plate, mid-ocean ridge (ophiolites) and supra-subduction. The book contributes to the wide debate on the nature of the fluids migrating into the mantle wedge, as well as on the different residential times of the subduction signature. In addition papers on intra-plate settings deal with the problem of relating various metasomatic signatures to one single metasomatic event through an infiltration-reaction process.

    Description / Table of Contents: Faults are primary focuses of both fluid migration and deformation in the upper crust. The recognition that faults are typically heterogeneous zones of deformed material, not simple discrete fractures, has fundamental implications for the way geoscientists predict fluid migration in fault zones, as well as leading to new concepts in understanding seismic/aseismic strain accommodation. This book captures current research into understanding the complexities of fault-zone internal structure, and their control on mechanical and fluid-flow properties of the upper crust. A wide variety of approaches are presented, from geological field studies and laboratory analyses of fault-zone and fault-rock properties to numerical fluid-flow modelling, and from seismological data analyses to coupled hydraulic and rheological modelling. The publication aims to illustrate the importance of understanding fault-zone complexity by integrating such diverse approaches, and its impact on the rheological and fluid-flow behaviour of fault zones in different contexts.

    Description / Table of Contents: The boundaries of rigid cratons can be affected by subsequent orogenic events, leading to ‘metacratonic’ characteristics not often properly recognized and still poorly understood. Major lithospheric thickening is absent and early events such as ophiolites are preserved; however, metacratonic boundaries are affected by major shear zones, abundant magmatism and mineralizations, and local high-pressure metamorphism. West Africa, marked by the large Eburnian (c. 2 Ga) West African craton, the absence of Mesoproterozoic events, the major Pan-African (0.9–0.55 Ga) mobile belts that generated the Peri-Gondawanan terranes, and the weaker but enlightening Variscan and Alpine orogenies, is an excellent place for tackling this promising concept of metacratonization. The papers in this book consider most of the West African craton boundaries, from the reworking of the Palaeoproterozoic terranes, through the Pan-African encircling terranes, the late Neoproterozoic-early Palaeozoic extension period and the Peri-Gondwanan terranes, the Variscan imprint to the current situation.

    Description / Table of Contents: There is a general consensus that for the next few decades at least, the Earth will continue its warming. This will inevitably bring about serious environmental problems. For human society, the most severe will be those related to alterations of the hydrological cycle, which is already heavily influenced by human activities. Climate change will directly affect groundwater recharge, groundwater quality and the freshwater-seawater interface. The variations of groundwater storage inevitably entail a variety of geomorphological and engineering effects. In the areas where water resources are likely to diminish, groundwater will be one of the main solutions to prevent drought. In spite of its paramount importance, the issue of ‘Climate Change and Groundwater’ has been neglected. This volume presents some of the current understanding of the topic.

    Description / Table of Contents: Stromatolites are the most intriguing geobiological structures of the entire history of the earth since the early beginning of the fossil record in the Archaean. Traditionally, stromatolites and related microbial sediments are interpreted as biosedimentological remains of biofilms and microbial mats. Stromatolites are important environmental and evolutionary archives that give us plenty of information on ancient habitats, biodiversity, and evolution of complex benthic biosystems. However, many aspects of the formation, biology, and geobiology of these structures are still cryptic and poorly understood. The symposium is dedicated to Ernst Louis Kalkowsky (1851–1938), who introduced the terms “Stromatolith” and “Ooid” to the earth science community in 1908.

    Chantilly, Va. : Mineralogical Society of America
    Description / Table of Contents: Hydrogen may be the most abundant element in the universe, but in science and in nature oxygen has an importance that is disproportionate to its abundance. Human beings tend to take it for granted because it is all around us and we breathe it, but consider the fact that oxygen is so reactive that in a planetary setting it is largely unstable in its elemental state. Were it not for the constant activity of photosynthetic plants and a minor amount of photo dissociation in the upper atmosphere, we would not have an oxygen-bearing atmosphere and we would not be here. Equally, the most important compound of oxygen is water, without which life (in the sense that we know it) could not exist. The role of water in virtually all geologic processes is profound, from formation of ore deposits to igneous petrogenesis to metamorphism to erosion and sedimentation. In planetary science, oxygen has a dual importance. First and foremost is its critical role in so many fundamental Solar System processes. The very nature of the terrestrial planets in our own Solar System would be much different had the oxygen to carbon ratio in the early solar nebula been somewhat lower than it was, because elements such as calcium and iron and titanium would have been locked up during condensation as carbides, sulfides and nitrides and even (in the case of silicon) partly as metals rather than silicates and oxides. Equally, the role of water ice in the evolution of our Solar System is important in the early accretion and growth of the giant planets and especially Jupiter, which exerted a major control over how most of the other planets formed. On a smaller scale, oxygen plays a critical role in the diverse kinds of physical evolution of large rocky planets, because the internal oxidation state strongly influences the formation and evolution of the core, mantle and crust of differentiated planets such as the Earth. Consider that basaltic volcanism may be a nearly universal phenomenon among the evolved terrestrial planets, yet there are basalts and basalts. The basalts of Earth (mostly), Earth's Moon, Vesta (as represented by the HED meteorites) and Mars are all broadly tholeiitic and yet very different from one another, and one of the primary differences is in their relative oxidation states (for that matter, consider the differences between tholeiitic and calc-alkaline magma series on Earth). But there is another way that oxygen has proven to be hugely important in planetary science, and that is as a critical scientific clue to processes and conditions and even sources of materials. Understanding the formation and evolution of our Solar System involves reconstructing processes and events that occurred more than 4.5 Ga ago, and for which the only contemporary examples are occurring hundreds of light years away. It is a detective story in which most of the clues come from the laboratory analysis of the products of those ancient processes and events, especially those that have been preserved nearly unchanged since their formation at the Solar System's birth: meteorites; comets; and interplanetary dust particles. For example, the oxidation state of diverse early Solar System materials ranges from highly oxidized (ferric iron) to so reducing that some silicon exists in the metallic state and refractory lithophile elements such as calcium exist occur in sulfides rather than in silicates or carbonates. These variations reflect highly different environments that existed in different places and at different times. Even more crucial has been the use of oxygen 3-isotope variations, which began almost accidentally in 1973 with an attempt to do oxygen isotope thermometry on high-temperature solar nebula grains (Ca-, Al-rich inclusions) but ended with the remarkable discovery (see Clayton 2008) of non-mass-dependent oxygen isotope variations in high-temperature materials from the earliest Solar System. The presolar nebula was found to be very heterogeneous in its isotopic composition, and virtually every different planet and asteroid for which we have samples has a unique oxygen-isotopic fingerprint.

    Description / Table of Contents: The 3D geological model is still regarded as one of the newest and most innovative tools for reservoir management purposes. The computer modelling of structures, rock properties and fluid flow in hydrocarbon reservoirs has evolved from a specialist activity to part of the standard desktop toolkit. The application of these techniques has allowed all disciplines of the subsurface team to collaborate in a common workspace. In today's asset teams, the role of the geological model in hydrocarbon development planning is key and will be for some time ahead. The challenges that face the geologists and engineers will be to provide more seamless interaction between static and dynamic models. This interaction requires the development of conventional and unconventional modelling algorithms and methodologies in order to provide more risk-assessed scenarios, thus enabling geologists and engineers to better understand and capture inherent uncertainties at each aspect of the geological model's life.

    Description / Table of Contents: Geological correlations of East Antarctica with adjoining continents have been puzzling geologists ever since the concept of a Gondwana supercontinent surfaced. Despite the paucity of outcrops because of ice cover, difficulty of access and extreme weather, the past 50 years of Japanese Antarctic Research Expeditions (JARE) has successfully revealed vital elements of the geology of East Antarctica. This volume presents reviews and new research from localities across East Antarctica, especially from Dronning Maud Land to Enderby Land, where the geological record preserves a history that spans the Archaean and Proterozoic. The reviews include extensive bibliographies of results obtained by geologists who participated in the JARE. Comprehensive geological, petrological and geochemical studies, form a platform for future research on the formation and dispersion of Rodinia in the Mesoproterozoic and subsequent assembly of Gondwana in the Neoproterozoic to Early Palaeozoic.

There are many examples of geological studies being ignored in policy and public action; this is in due in part to geoscientists being poor communicators. These papers document issues in communicating environmental geoscience, outline successes and failures through case studies, describe ways in which geoscientists can improve communication skills and show how new methods can make communication more effective.

    Description / Table of Contents: The geological record contains a fascinating diversity of reefs and shell accumulations. As my other biosedimentary structures, their facies characterization requires careful observation at outcrop and sample scale, and in thin-section to provide information about the global geometries, fabrics and textures respectively. This collection of papers encompasses the breadth of sedimentary geometries and facies displayed by Palaeozoic reefs, shell accumulations, and transitional composite deposits. The definition of reefs and shell concentrations has given rise to variations in nomenclature. The papers in this volume cover specific problems regarding the nomenclature and facies characterization of reefs, shell accumulations and transitional composite deposits. However, rather than attempt a complete revision of terms, the authors have touched on some of the important issues at this stage of development in the field: the main climatic, environmental and evolutionary factors that controlled the Palaeozoic development of shell accumulation and reefs.

    Description / Table of Contents: This book is the first peer-reviewed collection of papers focusing on the potential of myth storylines to yield data and lessons that are of value to the geological sciences. Building on the nascent discipline of geomythology, scientists and scholars from a variety of disciplines have contributed to this volume. The geological hazards (such as earthquakes, tsunamis, volcanic eruptions and cosmic impacts) that have given rise to myths are considered, as are the sacred and cultural values associated with rocks, fossils, geological formations and landscapes. There are also discussions about the historical and literary perspectives of geomythology. Regional coverage includes Europe and the Mediterranean, Afghanistan, Cameroon, India, Australia, Japan, Pacific islands, South America and North America. Myth and Geology challenges the widespread notion that myths are fictitious or otherwise lacking in value for the physical sciences.

    Description / Table of Contents: The idea for this book was conceived in early June, 2005 at a paleoaltimetry workshop held at Lehigh University, Lehigh, Pennsyalvania and organized by Dork Sahagian. The workshop was funded by the tectonics program at NSF, and was designed to bring together researchers in paleoaltimetry to discuss different techniques and focus the community on ways of improving paleoelevation estimates and consequent interpretations of geodynamics and tectonics. At this meeting, some commented that a comprehensive volume describing the different methods could help advance the field. I offered to contact the Mineralogical Society of America and the Geochemical Society about publishing a RiMG volume on paleoaltimetry. Because many of the techniques used to infer paleoelevations are geochemically-based or deal with thermodynamic principles, the GS and MSA agreed to the project. Two years and roughly 1000 e-mails later, our book has arrived. The book is organized into 4 sections: (1) Geodynamic and geomorphologic rationale (Clark). This chapter provides the broad rationale behind paleoaltimetry, i.e., why we study it. (2) Stable isotope proxies. These 4 chapters cover theory of stable isotopes in precipitation and their response to altitudinal gradients (Rowley), and stable isotopes sytematics in paleosols (Quade, Garzione and Eiler), silicates (Mulch and Chamberlain) and fossils (Kohn and Dettman). (3) Proxies of atmospheric properties. These 4 chapters cover temperature lapse rates (Meyer), entropy (Forest), and atmospheric pressure proxies, including total atmospheric pressure from gas bubbles in basalt (Sahagian and Proussevitch), and the partial pressure of CO2 (Kouwenberg, Kürshner, and McElwain). Note that clumped isotope thermometry (Quade, Garzione and Eiler) also provides direct estimates of temperature. (4) Radiogenic and cosmogenic nuclides. These 2 chapters cover low-temperature thermochronologic approaches (Reiners) and cosmogenic isotopes (Riihimaki and Libarkin). Some chapters overlap in general content (e.g., basic principles of stable isotopes in precipitation are covered to different degrees in all stable isotope chapters), but no attempt was made to limit authors' discussion of principles, or somehow attempt to arrive at a "consensus view" on any specific topic. Because science advances by critical discussion of concepts, such restrictions were viewed as counterproductive. This does mean that different chapters may present different views on reliability of paleoelevation estimates, and readers are advised to read other chapters in the book on related topics – they may be more closely linked than they might at first appear! I hope readers of this book will discover and appreciate the synergy among paleoaltimetry, climate change, and tectonic geomorphology. These interrelationships create a complex, yet rich field of scientific enquiry that in turn offers insights into climate and geodynamics.

    Description / Table of Contents: Where were the women in Geology? This book is a first as it unravels the diverse roles women have played in the history and development of geology as a science predominantly in the UK, Ireland and Australia, and selectively in Germany, Russia and US. The volume covers the period from the late eighteenth century to the present day and shows how the roles that women have played changed with time. These included illustrators, museum collectors and curators, educationalists, researchers and geologists. Originally as wives, sisters or mothers many were assistants to their male relatives. This book looks at all these forgotten women and for the first time historians and scientists together explore the contribution they made to this male-dominated subject. There are individual profiles on remarkable women: Catherine Raisin, Dorothea Bate, Cuvier's daughters, Grace Prestwich, Annie Greenly, Nancy Kirk, Margaret Crosfield, Ethel Skeat, Maria Ogivlie Gordon, Marie Stopes, Anne Phillips, Muriel Arber and Etheldred Bennett. Pulling together this extensive research uncovered common issues and generated emergent themes. The Editors have brought this new research together under these themes and tried to answer the question Where were the women in Geology? They go on to discuss how these role models can be applicable to today's society.

    Description / Table of Contents: The Devonian was a peculiar period, characterized by simplified plate tectonic configurations, climatic overheating and widely flooded continents. The bloom of fishes and ammonoids, extensive reef complexes, and the conquest of land indicate major biosphere innovations, punctuated by many global events, including two of the biggest mass extinctions. The Devonian was the first system for which subdivisions were formally defined. This was achieved by significant advances in pelagic biostratigraphy. The chronostratigraphic framework and interdisciplinary techniques allow us to correlate intervals or sudden events across facies boundaries, in order to reconstruct the sedimentary and evolutionary history of the system with highest precision. This volume honors the lifetime stratigraphic achievements of Michael Robert House (1930-2002). Based on case studies from Europe, North Africa and North America, it shows how the combination of biostratigraphy, chemostratigraphy, magnetostratigraphy, sequence stratigraphy and event stratigraphy can contribute to a much deeper understanding of both regional and global environmental change.

    Description / Table of Contents: We are poised to embark on a new era of discovery in the study of geomorphology. The discipline has a long and illustrious history, but in recent years an entirely new way of studying landscapes and seascapes has been developed. It involves the use of 3D seismic data. Just as CAT scans allow medical staff to view our anatomy in 3D, seismic data now allows Earth scientists to do what the early geomorphologists could only dream of - view tens and hundreds of square kilometres of the Earth's subsurface in 3D and therefore see for the first time how landscapes have evolved through time. This volume demonstrates how earth scientists are starting to use this relatively new tool to study the dynamic of a range of sedimentary environments.

    Description / Table of Contents: Structurally complex reservoirs form a distinct class of reservoir in which fault arrays and fracture networks, in particular, exert an overriding control on petroleum trapping and production behaviour. With modern exploration and production portfolios now commonly held in geologically complex settings, there is an increasing technical challenge to find new prospects and to extract remaining hydrocarbons from these reservoirs. This volume reviews our current understanding and ability to model the complex distribution and behaviour of fault and fracture networks, highlighting their fluid compartmentalizing effects and storage-transmissivity characteristics, and outlining approaches for predicting the dynamic fluid flow and geomechanical behaviour of these reservoirs. This collection of 25 papers provides an overview of recent progress and outstanding issues in the areas of (i) structural complexity and fault geometry, (ii) detection and prediction of faults and fractures, (iii) compartmentalizing effects of fault systems and complex siliciclastic reservoirs and (iv) critical controls affecting fractured reservoirs.

    Description / Table of Contents: The complexity of plate interactions and associated crustal deformation in the Eastern Mediterranean region is reflected by the numerous destructive earthquakes that have occurred throughout its history. Many of these have been well documented and studied. In addition, the Aegean region provides examples of core-complex formation, synchronous basin evolution and subsequent graben formation and continental extensional deformation following orogenic contraction. It is therefore considered to be a perfect natural laboratory for the study of these mechanisms. The region has been the subject of intensive research for several decades. This book contains current results and ideas regarding the geodynamics of the Aegean and Anatolia. It will be essential reading for all geoscientists with an interest in the structural evolution of the Eastern Mediterranean.

    Description / Table of Contents: Restraining and releasing bends are common, but enigmatic features of strike-slip fault systems occurring in all crustal environments and at regional to microscopic scales of observation. Regional-scale restraining bends are sites of mountain building, transpressional deformation and basement exhumation, whereas releasing bends are sites of topographic subsidence, transtensional deformation, basin sedimentation and possible volcanism and economic mineralization. Because restraining and releasing bends often occur as singular self-contained domains of complex deformation, they are appealing natural laboratories for Earth scientists to study fault processes, earthquake seismology, active faulting and sedimentation, fault and fluid-flow relationships, links between tectonics and topography, tectonic and erosional controls on exhumation, and tectonic geomorphology. This volume addresses the tectonic complexity and diversity of strike-slip restraining and releasing bends with 18 contributions divided into four thematic sections: (1) a topical review of fault bends and their global distribution; (2) bends, sedimentary basins and earthquake hazards; (3) restraining bends, transpressional deformation and basement controls on development; (4) releasing bends, transtensional deformation and fluid flow.

    Description / Table of Contents: The many kinds of porous geomaterials (rocks, soils, concrete, etc.) exhibit a range of responses when undergoing inelastic deformation. In doing so they commonly develop well-ordered fabric elements, forming fractures, shear bands and compaction bands, so creating the planar fabrics that are regarded as localization. Because these induced localization fabrics alter the bulk material properties (such as permeability, acoustic characteristics and strength), it is important to understand how and why localization occurs, and how it relates to its setting. The concept of damage (in several uses) describes both the precursor to localization and the context within which it occurs. A key theme is that geomaterials display a strong material evolution during deformation, revealing a close linkage between the damage and localization processes. This volume assembles perspectives from a number of disciplines, including soil mechanics, rock mechanics, structural geology, seismic anisotropy and reservoir engineering. The papers range from theoretical to observational, and include contributions showing how the deformed geomaterials emergent bulk characteristics, like permeability and seismic anisotropy, can be predicted. This book will be of interest to a wide range of geoscientists and engineers who deal with characterization of deformed materials.

    Description / Table of Contents: The Proterozoic and early Phanerozoic was a time punctuated by a series of significant events in Earth history. Glaciations of global scale wracked the planet, interfingered with dramatic changes in oceanic and atmospheric chemistry and marked changes in continental configuration. It was during these dynamic and ‘weedy’ times that metazoans first appeared. Their subsequent diversification culminated in the appearance of hard tissue skeletons and deep "farming" of the marine substrate in late Proterozoic and first few millions of years of the Phanerozoic. The papers in this book deal specifically with the precise timing of physical events and teasing out of the effects which these changing environments, climates, global chemistry and palaeogeography had on the development and diversification of animals, resulting in the spectacular Ediacaran/Vendian faunas of the late Precambrian.

    Description / Table of Contents: The dangers that we face from geohazards appear to be getting worse, especially with the impact of increasing population and global climate change. This collection of papers illustrates how remote sensing technologies - measuring, mapping and monitoring the Earth's surface from aircraft or satellites - can help us to rapidly detect and better manage geohazards. The hazardous terrains examined include areas of landslides, flooding, erosion, contaminated land, shrink-swell clays, subsidence, seismic activity and volcanic landforms. Key aspects of remote sensing are introduced, making this a book that can easily be read by those who are unfamiliar with remote sensing. The featured remote sensing systems include aerial photography and photogrammetry, thermal scanning, hyperspectral sensors, airborne laser altimetry (LiDAR), radar interferometry and multispectral satellites (Landsat, ASTER). Related technologies and methodogies, such as the processing of Digital Elevation Models and data analysis using Geographical Information Systems, are also discussed.

    Description / Table of Contents: The North China craton is the only known place where an Archaean craton with a thick tectospheric root lost half of that root in younger tectonism by processes such as delamination, convection, hydration-weakening, compositional change or some other mechanism. In this volume, authors provide data constraining the geometry and timing of root loss, aimed at understanding why and how continental roots are lost in general. Modelling how often this process may have occurred in the geological past, and how much lithospheric material has been recycled to the convecting mantle through this mechanism, could drastically change our current understanding of crustal growth rates and processes. Possible triggering mechanisms for root loss include collision of the South China (Yangtze) and North China cratons in the Triassic, the India–Asia collision, closure of the Solonker and Monhgol–Okhotsk oceans, Mesozoic subduction of the Pacific Plate beneath eastern China, impingement of mantle plumes, mantle hydration from long-term subduction and several rifting events. In this volume, we link studies of crustal tectonics with investigations aimed at determining the nature of and timing of the formation and loss of the root, in order to better-understand mechanisms of continental root formation, evolution and recycling/removal.

    Description / Table of Contents: This book summarizes our present understanding of the formation of passive continental margins and their ocean–continent transitions. It outlines the geological, geophysical and petrological observations that characterize extensional systems, and how such observations can guide and constrain dynamic and kinematic models of continental lithosphere extension, breakup and the inception of organized sea-floor spreading. The book focuses on imaging, mapping and modelling lithospheric extensional systems, at both the regional scale using dynamic models to the local scale of individual basins using kinematic models, with an emphasis on capturing the extensional history of the Iberia and Newfoundland margins. The results from a number of other extensional regimes are presented to provide comparisons with the North Atlantic studies; these range from the Tethyan realm and the northern Red Sea to the western and southern Australian margins, the Basin and Range Province, and the Woodlark basin of Papua New Guinea. All of these field studies, combined with lessons learnt from the modelling, are used to address fundamental questions about the extreme deformation of continental lithosphere.

    Description / Table of Contents: The book presents an overview of the main hazards affecting karst, including collapse and subsidence phenomena, hydrological hazards and human-induced geohazards. Consideration is also given to the problems of geohazard management in karst. The geological and hydrological properties of karst terrains make them among the most fragile in the world and pose serious problems for land managers. Sustainable development in these terrains requires efforts to limit geohazards of anthropogenic origin and to recognize and mitigate against those of natural origin. Aimed at providing the reader with worldwide case studies, the contributions cover a range of geological and morphological settings. Geographically, the fourteen papers discuss very different karst areas, from North America, the Caribbean and Asia to several karst areas in Europe, including the British Isles, Spain, France and Italy.

    Description / Table of Contents: For the geoscientist, interest in sediment dynamics relates to the understanding of modern processes, together with their extrapolation to the interpretation of ancient deposits within the stratigraphic record. Over the years, various measurement techniques and scientific approaches have been applied to the determination of sediment transport pathways and the derivation of erosion, transport and deposition rates. Recently, a number of new techniques and approaches have been developed, associated with different temporal and spatial scales, and it is appropriate and timely to review a representative selection, by reference to recently undertaken coastal and shelf investigations. The various contributions in the volume cover, for example: optical and acoustic backscatter measurements; particle tracking; the use of mutibeam imagery; grain-size trend analysis; and analytic, numerical and conceptual modelling. Although no single method provides a complete solution to the problem posed, this overview will assist sedimentologists and sediment dynamicists in their selection of the most appropriate approaches, towards the establishment of ‘high confidence’ in the interpretation of sediment transport rates and directions.

    Description / Table of Contents: This book provides an overview of the principal environments, main processes and manifestations of hypogenic speleogenesis, and refines the relevant conceptual framework. It consolidates the notion of hypogenic karst as one of the two major types of karst systems (the other being epigenetic karst). Karst is viewed in the context of regional groundwater flow systems, which provide the systematic transport and distribution mechanisms needed to produce and maintain the disequilibrium conditions necessary for speleogenesis. Hypogenic and epigenic karst systems are regularly associated with different types, patterns and segments of flow systems, characterized by distinct hydrokinetic, chemical and thermal conditions. Epigenic karst systems are predominantly local systems, and/or parts of recharge segments of intermediate and regional systems. Hypogenic karst is associated with discharge regimes of regional or intermediate flow systems. Various styles of hypogenic caves that were previously considered unrelated, specific either to certain lithologies or chemical mechanisms are shown to share common hydrogeologic genetic backgrounds. In contrast to the currently predominant view of hypogenic speleogenesis as a specific geochemical phenomenon, the broad hydrogeological approach is adopted in the book. Hypogenic speleogenesis is defined with reference to the source of fluid recharge to the cave-forming zone, and type of flow system. It is shown that confined settings are the principal hydrogeologic environment for hypogenic speleogenesis. However, there is a general evolutionary trend for hypogenic karst systems to lose their confinement due to uplift and denudation and due to their own expansion. Confined hypogenic caves may experience substantial modification or be partially or largely overridden under subsequent unconfined (vadose) stages, either by epigenic processes or continuing unconfined hypogenic processes, especially when H2S dissolution mechanisms are involved. Hypogenic confined systems evolve to facilitate cross-formational hydraulic communication between common aquifers, or between laterally transmissive beds in heterogeneous soluble formations, across cave-forming zones. The latter originally represented low-permeable, separating units supporting vertical rather than lateral flow. Layered heterogeneity in permeability and breaches in connectivity between different fracture porosity structures across soluble formations are important controls over the spatial organization of evolving ascending hypogenic cave systems. Transverse hydraulic communication across lithological and porosity system boundaries, which commonly coincide with major contrasts in water chemistry, gas composition and temperature, is potent enough to drive various disequilibrium and reaction dissolution mechanisms. Hypogenic speleogenesis may operate in both carbonates and evaporites, but also in some clastic rocks with soluble cement. Its main characteristic is the lack of genetic relationship with groundwater recharge from the overlying or immediately adjacent surface. It may not be manifested at the surface at all, receiving some expression only during later stages of uplift and denudation. In many instances, hypogenic speleogenesis is largely climate-independent. There is a specific hydrogeologic mechanism inherent in hypogenic transverse speleogenesis (restricted input/output) that suppresses the positive flow-dissolution feedback and speleogenetic competition in an initial flowpath network. This accounts for the development of more pervasive channeling and maze patterns in confined settings where appropriate structural prerequisites exist. As forced-flow regimes in confined settings are commonly sluggish, buoyancy dissolution driven by either solute or thermal density differences is important in hypogenic speleogenesis. In identifying hypogenic caves, the primary criteria are morphological (patterns and meso-morphology) and hydrogeological (hydrostratigraphic position and recharge/flow pattern viewed from the perspective of the evolution of a regional groundwater flow system). Elementary patterns typical for hypogenic caves are network mazes, spongework mazes, irregular chambers and isolated passages or crude passage clusters. They often combine to form composite patterns and complex 3-D structures. Hypogenic caves are identified in various geological and tectonic settings, and in various lithologies. Despite these variations, resultant caves demonstrate a remarkable similarity in cave patterns and meso-morphology, which strongly suggests that the hydrogeologic settings were broadly identical in their formation. Presence of the characteristic morphologic suites of rising flow with buoyancy components is one of the most decisive criteria to identify hypogenic speleogenesis. Hypogenic speleogenesis is much more widespread than it was previously presumed. Hypogenic caves include many of the largest, by integrated length and by volume, documented caves in the world. The refined conceptual framework of hypogenic speleogenesis has broad implications in applied fields and promises to make karst and cave expertise more demanded by practicing hydrogeology, geological engineering, economic geology and mineral resource industries. Any generalization of hydrogeology of karst aquifers, as well as approaches to practical issues and resource prospecting in karst regions, should take into account the different nature and characteristics of hypogenic and epigenic karst systems. Hydraulic properties of karst aquifers, evolved in response to hypogenic speleogenesis, are characteristically different from epigenic karst aquifers. In hypogenic systems, cave porosity is roughly an order of magnitude greater, and areal coverage of caves is five times greater than in epigenic karst systems. Hypogenic speleogenesis commonly results in more isotropic conduit permeability pervasively distributed within highly karstified areas measuring up to several square kilometers. Although being vertically and laterally integrated throughout conduit clusters, hypogenic systems, however, do not transmit flow laterally for considerable distances. Hypogenic speleogenesis can affect regional subsurface fluid flow by greatly enhancing initially available cross-formational permeability structures, providing higher local vertical hydraulic connections between lateral stratiform pathways for groundwater flow, and creating discharge segments of flow systems, the areas of low-fluid potential recognizable at the regional scale. Discharge of artesian karst springs, which are modern outlets of hypogenic karst systems, is often very large and steady, being moderated by the high karstic storage developed in the karstified zones and by the hydraulic capacity of an entire artesian system. Hypogenic speleogenesis plays an important role in conditioning related processes such as hydrothermal mineralization, diagenesis, and hydrocarbon transport and entrapment. The appreciation of the wide occurrence of hypogenic karst systems, marked specifics in their origin, development and characteristics, and their scientific and practical importance, calls for revisiting and expanding of the current predominantly epigenic paradigm of karst and cave science.

    Description / Table of Contents: Over 25 years ago, Volume 9 of Reviews in Mineralogy: Amphiboles and Other Hydrous Pyriboles seemed to contain all that was possible to know about this group of fascinating minerals. The subsequent twenty-five years have shown that this assessment was wrong: Nature was keeping a lot in reserve, and has since revealed considerable new complexity in the constitution and behavior of amphiboles. Some of the advances in knowledge have been due to the use of new experimental techniques, some have been due to the investigation of hitherto neglected rock-types, and some have been due to the development of new ideas. The identification and systematic investigation of variable LLE (Light Lithophile Elements), particularly Li and H, led to the identification of several new amphibole species and the recognition that variable Li and H play an important role in chemical variations in amphiboles from both igneous and metamorphic parageneses. In turn, this work drove the development of microbeam SIMS to analyze LLE in amphiboles. Detailed mineralogical work on metasyenites showed hitherto unexpected solid-solution between Na and Li at the M(4) site in monoclinic amphiboles, a discovery that has upset the current scheme of amphibole classification and nomenclature and initiated new efforts in this direction. Systematic and well-planned synthesis of amphiboles, combined with careful spectroscopy, has greatly furthered our understanding of cation and anion order in amphiboles. The use of bond-valence theory to predict patterns of SRO (Short-Range Order) in amphiboles, and use of these predictions to understand the infrared spectra of well-characterized synthetic-amphibole solid-solutions, has shown that SRO is a major feature of the amphibole structure, and has resulted in major advances in our understanding of SRO in minerals. There has been significant progress relating changes in amphibole composition and cation ordering to petrogenetic conditions and trace-element behavior. Work on the nature of fibrous amphiboles and their toxicity and persistence in living organisms has emphasized the importance of accurate mineralogical characterization in environmental and health-related problems. The current volume has taken a different approach from previous volumes concerned with major groups of rock-forming minerals. Some of the contents have previously been organized by the investigative technique or groups of similar techniques: crystal-structure refinement, spectroscopy, TEM etc. Here, we have taken an approach that focuses on aspects of amphiboles rather than experimental techniques: crystal chemistry, new compositions, long-range order, short-range order etc., and all experimental results germane to these topics are discussed in each chapter. The intent of this approach is to focus on amphiboles, and to emphasize that many techniques are necessary to fully understand each aspect of the amphiboles and their behavior in both natural and industrial processes.

    Description / Table of Contents: Understanding the process underlying the origin of Earth magnetic field is one of the greatest challenges left to classical Physics. Geomagnetism, being the oldest Earth science, studies the Earth’s magnetic field in its broadest sense. The magnetic record left in rocks is studied in Paleomagnetism. Both fields have applications, pure and applied: in navigation, in the search for minerals and hydrocarbons, in dating rock sequences, and in unraveling past geologic movements such as plate motions they have contributed to a better understanding of the Earth. Consisting of more than 300 articles written by ca 200 leading experts, this authoritative reference encompasses the entire fields of Geomagnetism and Paleomagnetism in a single volume. It describes in fine detail at an assessable level the state of the current knowledge and provides an up-to-date synthesis of the most basic concepts. As such, it will be an indispensable working tool not only for geophysicists and geophysics students but also for geologists, physicists, atmospheric and environmental scientists, and engineers.

    Description / Table of Contents: In the last four centuries geologists have traversed the globe, searching for economically important materials or simply to satisfy their intellectual curiosity. Geologists have often been at the vanguard of scientific exploration. The microscopist Robert Hooke explored the Isle of Wight, and Charles Darwin the Cape Verde islands and parts of South America. The volcanic wonders of Italy and central France attracted native and foreign visitors including Lyell and Murchison. The Tyrrell brothers faced great hardship in northern Canada, as did the actor and mineralogist Charles Lewis Giesecke in Greenland. The development of Sydney, Australia depended on finding limestone for building. French geologists relied on camels in the Sahara, and Grenville Cole trusted his tricycle to carry him across Europe. Four Centuries of Geological Travel: The Search for Knowledge on Foot, Bicycle, Sledge and Camel focuses on the complexities of geological exploration and will be of particular interest to Earth scientists, historians of science and to the general reader interested in science.

    Description / Table of Contents: This book is an exploration of varying approaches to the study of the deposition, diagenesis and stratigraphy of evaporites. The volume includes papers from chemical modellers, who work on the basis of geochemical representations of the formative water bodies, and from basin-wide depositional-stratigraphical modellers, who propose depositional scenarios that are fitted to individual basinal pictures. Until now there have been only a few studies of evaporite formation that explain the characteristic features we observe in the real rock record. This volume is a collection of relevant papers in which these features are integrated in a realistic manner, based on our new understanding of saline water bodies, to the diverse tectonic, chemical and depositional constraints of their individual basins. In additional there are several review articles that offer oversight and extensive referencing of basins worthy of further study. This book is a valuable resource for sedimentologists and stratigraphers looking for an up-to-date reference on evaporite deposits.

    Description / Table of Contents: The study of reservoir and repository performance requires the integration of many different fields in Earth sciences, among them rock physics and geomechanics. The aim of this book is to emphasize how rock physics and geomechanics help to get a better insight into important issues linked to reservoir management for exploitation of natural resources, and to repository safety assessment for hazardous waste storage in geological environment. The studies presented here deal with the hydromechanical coupling in fractured rocks, the key experiments in safety assessment of repositories, the development of damaged zones during excavation in a shaley formation, the influence of temperature on the properties of shales, the poroelastic response of sandstones, the development and propagation of compaction bands in reservoir rocks, imaging techniques of geomaterials, the characterization and modelling of reservoirs using 4D seismic data, the mechanical behaviour of fractured rock masses, the petrophysical properties of fault zones, models for rock deformation by pressure solution and the elastic anisotropy in cracked rocks.

    Description / Table of Contents: There has lately been a growth in the number and level of studies of contourite deposits. Most recent studies of contourites have two major lines of interest. One, propelled by the oil industry's continuous move into increasingly deep waters, concerns their economic significance. The other involves the stratigraphic/ palaeoceanographic record of ocean circulation changes imprinted on contourite deposits that can be a key to understanding better the climate-ocean connection. The application of many different theoretical, experimental and empirical resources provided by geophysics, sedimentology, geochemistry, petrology, scale modeling and field geology are used in the 16 papers of this volume, proposing answers to those two main aspects. The papers are subdivided into two major categories (economic interest and stratigraphic/palaeoceanographic significance), with case studies ranging from well-documented drifts to new examples of modern and fossil series, involving a large diversity of geographic and physiographic scenarios worldwide.

    Description / Table of Contents: Stone buildings and monuments from the cultural centres of many of the world's urban areas. Frequently these areas are prone to high levels of atmospheric pollution that promote a variety of aggressive stone decay processes. Because of this, stone decay is now widely recognized as a severe threat to much of our cultural heritage. If this threat is to be successfully addressed it is essential that the symptoms of decay are clearly identified, that appropriate stone properties are accurately characterized and that decay processes are precisely identified. It is undoubtedly the case that successful conservation has to be underpinned by a comprehensive understanding of the causes of decay and the factors that control them. The accomplishment of these demanding goals requires an interdisciplinary approach based on co-operation between geologists, environmental scientists, chemists, material scientists, civil engineers, restorers and architects. In pursuit of this collaboration, this volume aims to strengthen the knowledge base dealing with the causes, consequences, prevention and solution of stone decay problems.

    Description / Table of Contents: Fractured reservoirs contain a significant proportion of the global hydrocarbon reserves; however, they commonly exhibit unpredictable and extreme production behaviour. To develop such reservoirs it is necessary to obtain the best understanding possible of the fracture network and its impact on the fluid flow within the reservoir, using the full range of geoscience and engineering datasets available at all scales. This book presents an overview of current techniques and the latest technologies used to understand and exploit fractured reservoirs. The contributions are organized into sections on outcrop analogues, the application of geophysical techniques for fracture detection and imaging, numerical and analogue modelling and case studies from fields in the Middle East, Europe and North America. A number of the case studies also consider ways of assessing uncertainties in fracture geometry description and the implications for effective reservoir management.
