Beschreibung / Inhaltsverzeichnis: Exciting developments in earthquake science have benefited from new observations, improved computational technologies, and improved modeling capabilities. Designing models of the earthquake generation process is a grand scientific challenge due to the complexity of phenomena and range of scales involved from microscopic to global. Such models provide powerful new tools for the study of earthquake precursory phenomena and the earthquake cycle. Through workshops, collaborations and publications, the APEC Cooperation for Earthquake Simulations (ACES) aims to develop realistic supercomputer simulation models for the complete earthquake generation process, thus providing a "virtual laboratory" to probe earthquake behavior. Part II of the book embraces dynamic rupture and wave propagation, computational environment and algorithms, data assimilation and understanding, and applications of models to earthquakes. This part also contains articles on the computational approaches and challenges of constructing earthquake models.

Beschreibung / Inhaltsverzeichnis: This special issue contains contributions presented at the international workshop Seismic Waves in Laterally Inhomogeneous Media V, which was held at the Castle of Zahrádky, Czech Republic, June 5 - 9, 2000. The workshop, which was attended by about 60 seismologists from 16 countries, was devoted mainly to the current state of theoretical and computational means of study of seismic wave propagation in complex structures. The special issue begins with papers dealing with the study and the application of the ray methods. Problems such as coupling of quasi-shear waves or smoothing of models for effective ray computations are dealt with. Applications of the ray methods in seismic exploration are presented. Further, directional wavefield decomposition, phase space, path integral and parabolic equation methods are discussed. Attention is also devoted to attenuation and scattering problems, and to seismic inversion problems.

Beschreibung / Inhaltsverzeichnis: Concepts and methods of fractal geometry penetrate various branches of human knowledge to an increasing degree. This tendency is particularly striking in the geosciences, because many processes occurring in and on the Earth result in time dependences and spatial patterns that have a fractal character. The contributions in this volume arose from the "3rd International Symposium on Fractals and Dynamic Systems in Geosciences", held at Stara Lesna, Slovakia in June, 1997. The volume contains new ideas and applications of fractal geometry in such diverse branches of geoscience as engineering geology, the physics of the lithosphere (including faulting, seismicity, and fluid flow), and climate behavior.

Beschreibung / Inhaltsverzeichnis: The Azores-Tunisia region is formed by the western part of the plate boundary between Eurasia and Africa. This plate boundary presents a complex nature due to its proximity to the pole of rotation of the African plate. This condition produces crustal extensions and normal faulting at the Azores archipelago, transcurrent motion with strike slip faulting at the center part of the Azores-Gibraltar fault and at the eastern end, from the Gulf of Cadiz to Tunisia, plate convergence with reverse faulting. In this last part, the collision of Iberia with northern Morocco produces complex phenomena with intermediate depth and deep earthquakes and an extensional regime at the Alboran sea. Recently, new evidence has been gathered in this region based on observations from geology, geodesy, mainly through GPS measurements, seismology, especially with the installation of broad-band stations, and other fields of geophysics, such as paleomagnetism and gravimetry.

Beschreibung / Inhaltsverzeichnis: In many past and recent earthquakes it has been shown that the local conditions and, in particular, the local geology have a great influence on the observed seismic ground motion and, consequently, on the damage distribution in housing, industrial stock, and life-lines. Seismic microzoning is the usual procedure to have these local effects taken into account for engineering design and land-use planning, being a useful tool for earthquake risk mitigation. This volume presents a collection of papers mainly originated from a workshop on Seismic Microzoning, organized during the 23rd General Assembly of the European Geophysical Society (EGS) in Nice, France in April 1998. The workshop dealt with various geophysical tools for analysing the effects of the local soils of subsurface geology on seismic ground motion, namely the methods using experimental data such as microtremors, and the theoretical/numerical 1-D and 2-D modelling methods. Additional contributions discussing techniques for characterising soil properties, microzoning applications to several urban areas, and others were added to the volume to broaden this important topic.

Beschreibung / Inhaltsverzeichnis: In September 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a network of 321 monitoring stations distributed around the globe, a data communications network, an international data center, and onsite inspections, to verify compliance. The problem of identifying small-magnitude banned nuclear tests and discriminating between such tests and the background of earthquakes and mining-related seismic events, is a challenging research problem. Because they emphasize CTBT verification research, the 12 papers in this special volume primarily addresses regional data recorded by a variety of arrays, broadband stations, and temporarily deployed stations. Nuclear explosions, earthquakes, mining-related explosions, mine collapses, single-charge and ripple-fired chemical explosions from Europe, Asia, North Africa, and North America are all studied. While the primary emphasis is on short-period, body-wave discriminants and associated source and path corrections, research that focuses on long-period data recorded at regional and teleseismic distances is also presented Hence, these papers demonstrate how event identification research in support of CTBT monitoring has expanded in recent years to include a wide variety of event types, data types, geographic regions and statistical techniques.

Beschreibung / Inhaltsverzeichnis: In September 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a network of 321 monitoring stations distributed around the globe, a data communications network, an international data centre (IDC), and on-site inspections, to verify compliance. This volume contains research papers focusing on seismic ecent location in the CTBT context. The on-site inspection protocol of the treaty specifies a search area not to exceed 1000 square km. Much of the current research effort is therefore directed towards refining the accuracy of event location by including allowances for three-dimensional structure within the Earth. The aim is that the true location of each event will lie within the specified source zone regarding postulated location. The papers in this volume cover many aspects of seismic event location, including the development of algorithms suitable for use with three-dimensional models, allowances for regional structure, use of calibration events and source-specific station corrections. They provide a broad overview of the current international effort to improve seismic event location accuracy, and the editors hope that it will stimulate increased interest and further advances in this important field.

Beschreibung / Inhaltsverzeichnis: The wide distribution of dolomite rocks in North American, Middle- and Far-Eastern hydrocarbon reservoirs is reason enough for their intensive study. In this volume dolomite enthusiasts review progress and define the current boundaries of dolomite research, related particularly to the importance of these rocks as reservoirs. As might be expected, reviews provide critical analyses of past ideas on origins and why many are no longer tenable. Discussions range between conceptual models and numerical simulations of the flow paths of dolomitizing fluids, geochemical modelling, and microbial mediation. Case studies from areas as diverse as North America, the Middle East, SE Asia and Australia provide a solid background but illustrate important differences in views on the origins of these enigmatic rocks.

Beschreibung / Inhaltsverzeichnis: This book gives an up-to-date overview of the physical geology of sub-volcanic intrusions. Topics covered in this wide-ranging volume include important aspects of the field geology and physical volcanology of sills, laccoliths and sub-volcanic complexes, magma-sediment interaction and numerical and experimental studies aimed at quantifying more precisely the emplacement mechanics of high-level magmatic intrusions. Provocative papers ask whether laccoliths and high-level sills are forming today, and question the nature of the relationship between high-level intrusions and contemporaneous volcanic activity. Several contributions also deal with the more applied aspects of high-level magma emplacement and 3D seismic imaging of sill and laccolith complexes as relevant to the hydrocarbons industry. It is hoped that with the publication of this volume a consensus will emerge that will help to advance our understanding of the more important physical factors governing the emplacement of high-level intrusions in the continental crust, along with their wider geotectonic implications.

Beschreibung / Inhaltsverzeichnis: The Cretaceous submarine Ontong Java Plateau, in the western Pacific Ocean, is the most volumnous of the world's large igneous provinces(LIPs), and represents the largest known magmatic event on Earth. LIPs are the products of basaltic volcanism on a scale and at an effusion rate not seen on Earth at the present time, and their formation may have had significant effects on the Earth's climate and biosphere. The currently favoured explanation for LIP formation is the rapid decompression and melting of anomalously hot mantle in the heads of newly ascended mantle plumes. This volume summarizes the results of research aimed principally at testing the plume-head hypothesis for the formation of the Ontong Java Plateau, and presents the results of integrated studies following recent basement drilling on the plateau by the Ocean Drilling Program Nineteen papers cover topics as diverse as petrology, geochemistry, tectonics, volcanology, paleomagnatism and biostratigraphy.

Beschreibung / Inhaltsverzeichnis: Bivalves are key components of Recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. In the last few years there has been enormous expansion in the range of techniques available to both palaeontologists and zoologists and key discoveries of new faunas which shed new light on the evolutionary biology of this important class. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution. This series of 32 original papers tackles key issues including: up to date molecular phylogenies of major groups; new hard and soft tissue morphological cladistic analyses; reassessments of the early Palaeozoic radiation; important new observations on form and functional morphology; analyses of biogeography and biodiversity; novel (palaeo)ecological studies

Beschreibung / Inhaltsverzeichnis: The flow of glacier ice can produce structures that are striking and beautiful. Associated sediments,too, can develop spectacular deformation structures, and examples are remarkbly well preserved in Quaternary deposits. Although such features have long been recognized, they are now the subject of new attention from glaciologists and glacial geologists. This collection of papers addresses how the methods for unravelling deformation structures evolved in recent years by structural geologists can be used for glacial materials, and the opportunities offered to structural geologists by glacial materials for studying deformation in rocks.

Beschreibung / Inhaltsverzeichnis: The ten articles in this book describe the mode of emplacement of various types of intrusions (salt diapirs, mud volcanoes and magmatic bodies) by means of theoretical reasoning, analogue and analytical modelling, interpretation of seismic and field data, and geodetic surveying. All the articles emphasize the role of regional tectonics in driving or controlling the emplacement of the intrusions. The selection of articles includes examples from Spain, Romania, onshore and offshore Italy, the Eastern Mediterranean, Israel and iran. Better understanding of the mode of emplacement of these intrusions has applications in hydrocarbon exploration (e.g., where salt structures or mud diapirs are present) and in the mining industry (where mineralization is related to the emplacement of batholiths).

Beschreibung / Inhaltsverzeichnis: This volume contains 23 papers from a range of international contributors, describing recent research into the tectonics and magmatism of Turkey and its surroundings. This region is sited at the collision zone between Eurasia and Afro-Arabia and, as such, provides an extraordinarily complete and well-exposed record of the staged tectonic evolution of this sector of the Alpine-Himalayan orogen. The geological history of this area involves separation of continental fragments from the margin of Gondwana, their migration across the Tethyan oceans, the subsequent closure of these oceans and, finally, the development of the neotectonic regime, which continues to evolve to the present day. Such a comprehensive record is relevant to the understanding of collisional zones worldwide. The volume is divided into five sections: Tethyan evolution, Neotethyan ophiolites, post-Tethyan basin evolution, neotectonics and igneous activity. The first two sections deal with Tethyan oceans, whose growth and subsequent closure dominated the geodynamic framework in the Mesozoic and Cenozoic. The subsequent sections deal with more recent geological developments from the Balkan Peninsula in the west to the Transcaucasus in the east that followed consumption of the Tethyan oceans. There is a broad mix of papers throughout the volume: wide-ranging review papers on ocean development and extensional tectonics are followed by detailed descriptions of petrology and geochemistry and geographically focused studies on basin evolution, specific aspects of extensional and strike-slip tectonics and discussions of the relationship of magmatic activity to the tectonic development of the area.

Beschreibung / Inhaltsverzeichnis: Exciting developments in earthquake science have benefited from new observations, improved computational technologies, and improved modeling capabilities. Designing models of the earthquake of the earthquake generation process is a grand scientific challenge due to the complexity of phenomena and range of scales involved from microscopic to global. Such models provide powerful new tools for the study of earthquake precursory phenomena and the earthquake cycle. Through workshops, collaborations and publications the APEC Cooperation for Earthquake Simulations (ACES) aims to develop realistic supercomputer simulation models for the complete earthquake generation process, thus providing a "virtual laboratory" to probe earthquake behavior. Part I of the book covers microscopic simulations, scaling physics and earthquake generation and cycles. This part also focuses on plate processes and earthquake generation from a macroscopic standpoint.

Beschreibung / Inhaltsverzeichnis: This volume presents summaries of recent research results on the related subjects of source processes and explosion yield estimation, which are important elements of any treaty verification system. The term Source Processes, in the context of nuclear test monitoring, refers to a wide range of research topics. In a narrow definition, it describes the complex physical phenomena that are directly associated with a nuclear explosion, and the catastrophic deformation and transformation of the material surrounding the explosion. In a broader sense, it includes a host of topics related to the inference of explosion phenomena from seismic and other signals. A further widening of the definition includes the study and characterization of source processes of events other than nuclear, such as earthquakes and, in particular, mining explosions. This latter research is especially important relative to the question of identifying and discriminating nuclear explosions from other seismic events. Explosion Yield Estimation deals with the corresponding inverse problem of inferring explosion source characteristics through analyses of the various types of seismic signals produced by the explosion. This is a complex technical task which has been the focus of some of the most contentious treaty monitoring debates. The current compilation of eight articles on Source Processes and six articles on Explosion Yield Estimation gives a good representation of state-of-the-art research currently being conducted in the broad area of seismic source characterization in the context of nuclear test monitoring.

Beschreibung / Inhaltsverzeichnis: The topics included in this issue deal with many aspects of volcanic and seismic activity, two of the natural hazards of geological origin that have the greatest impact and pose the predominant risk to society. This book comprises eighteen papers, most of which were presented at an international seminar organized and held at the Complutense University of Madrid in October 2001. The papers address geodetic, geophysical and geochemical effects caused by seismic and volcanic activity; monitoring of volcanic and seismic processes using space and terrestrial techniques; complementarity of these techniques; theoretical modelling of volcanic and seismic processes; inverse problem; interpretation of observations; hazards; seismicity patterns and application.

Beschreibung / Inhaltsverzeichnis: Geological prior information represents a new and emerging field within the geosciences. Prior information is the term used to describe previously existing knowledge that can be brought to bear on a new problem. This volume describes a range of methods that can be used to find solutions to practical and theoretical problems using geological prior information, and the nature of geological information that can be so employed. As such, this volume defines how geology can be influential far beyond the confines of its own definition.

Beschreibung / Inhaltsverzeichnis: This publication reflects a growing appreciation of yhe extent to which turbidite depositional system development is fundamentally affected by basin-floor topography. In the many turbidite and turbidite hydrocarbon reservoirs, depositional patterns have been moderately to strongly confined by pre-existing slopes; thus 'submarine fans' may be far from fan-shaped where constrained by significant bathymetric features. This volume examines aspects of sediment dispersal and accumulation in deep-water systems where sea-floor topography has exerted a decisive control on deposition, and explores the associated controls on hydrocarbon reservoir architecture and heterogeneity. The papers presented here offer a global perspective, which is wide-ranging in terms of approach as well as location, including contrasting reviews and case studies of outcrop, subsurface, modern and experimental systems. This book will be of use both to academic geologists and to geoscience professionals in industry dealing with characterization and modelling of deep-water clastic reservoirs.

Beschreibung / Inhaltsverzeichnis: Recycling of oceanic plate back into the Earth’s interior at subduction zones is one of the key processes in Earth evolution. Volcanic arcs, which form above subduction zones, are the most visible manifestations of plate tectonics, the convection mechanism by which the Earth loses excess heat They are probably also the main location where new continental crust is formed, the so-called ‘subduction factoiy’ About 400f modern subduction zones on Earth are intra-oceanic. These subduction systems are generally simpler than those at continental margins as they commonly have a shorter history of subduction and their magmas are not contaminated by ancient sialic crust. They are therefore the optimum locations for studies of mantle processes and magmatic addition to the crust in subduction zones. This volume contains a collection of papers that exploit the relative simplicity of intra-oceanic subduction systems to provide insights into the tectonic, magmatic and hydrothermal processes associated with subduction.

Beschreibung / Inhaltsverzeichnis: The 32 research papers in this volume examine the mode and nature of igneous, metamorphic, tectonic, sedimentological and biological processes associated with the evolution of ophiolites in Earth's history. Divided into six sections, the book presents a wealth of new data and syntheses from ophiotites around the world. Introductory chapters review the distribution of ophiolites in space and time and present a synoptic discussion on their importance in Earth history. Papers in the second section present diverse data from Tethyan ophiolites and provide refined geodynamic models for their evolution. The following two sections present case studies documenting magmatic, metamorphic and tectonic processes in ophiolite genesis and hydrothermal and biogenic alteration of fossil oceanic crust. Mechanisms of ophiolite emplacement are explored in Section V with a focus on the Semail massif (Oman). The last section examines the regional occurrence and geodynamic significance of ophiolite belts on different continents. The book reflects the contemporary work of the international community in a most up-to-date treatment of process-oriented questions on the evolution of ophiolites.
