Description / Table of Contents: Geoscientists need to familiarize themselves with the characteristics of actual plate motions. A popular, current thesis relates the state of stress to the degree of coupling of the two convergent plates. Recent two-dimentional, finite element modelling has demonstrated how the stress in the overriding plate is critically dependent on wether the subduction zone is locked (i.e. high degree of coupling) or unlocked. Thus the compressional stress regime occurs in locked systems, and extensional strees in unlocked systems; a gradient from compression in the fore-arc to extension in the back-arc is said to characterize partially locked system. However, studies of the strain field in real cases (modern arc regions) clearly indicate the prevalence of subhorizontal extension orientated nearly perpendicular to the arc. Implicit in these real observations is the suggestion that stresses resulting from plate coupling are either not transmitted to the volcanic arc, or else locked subduction zones are uncommon and extension may be the normal mode of behaviour. The rationale and evidence for extension and coeval volcanism at consuming plate margins is presented. Using mainly Cenozoic case histories for oceanic and continental margin arcs, structural evidence is presented, which demonstrates that volcanism in most arc systems is contemporaneous with normal faulting and subsidence as a general case. Representive, modern geochemical data sets are provided and integrated in a petrological discussion for each case history. The western Pacific, now widely regard as a type region for the study of convergent plate margin processes, is particularly well represented. Also included is evidence from less commonly insvestigated regions, where subduction has ceased or is no longer obvious but an association with an arc is unequivocal. By these means, it is hoped that this volume contains a representative cross-section of current research on extension-related arc volcanism in broadest sense, and that it will stimulate further discussion and research into the complex tectonics and petrology of covergent plate margins.

Description / Table of Contents: Digital signal processing has become more and more an integral part of observational seismology. While it offers unprecedented power in extracting information from seismic signals, it comes at the price of having to learn a variety of new skills. Dealing with digital seismic data requires at least a basic understanding of digital signal processing. Taking the calculation of true ground motion as the guiding problem, this course covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion and an introduction to spectral analysis of digital signals. It contains a number of examples and exercises that can be reproduced using the PITSA software package (Scherbaum and Johnson 1993) or similar programs.

Description / Table of Contents: PREFACE This volume contains a selection of papers presented and discussed at the COMTAGWorkshop on "Dynamics and Geomorphology of Mountain Rivers". COMTAG (Commission on Theory, Measurement and Application in Geomorphology) is a commission of the International Geographical Union (IGU). The meeting was held in the monastery of Benediktbeuern in the Bavarian Alps in June 1992. The main objective of the meeting was to review the most recent developments in research on river bed dynamics and bedload transport in mountain rivers. Questions of mountain torrent control and environmental protection were also addressed. The general theme of the meeting finds its appropriate scientific and spatial location in the long tradition of bedload transport studies carried out in the fluvially active German Alps, which are often affected by flood and mass movement hazards. The conference provided an impulse for discussions between researchers in the fields of mountain torrent hydrology, water resources management and bedload transport modelling. In the five years preceding the meeting the editors of this volume had headed a DFG (Deutsche Forschungsgemeinschaft) project on "Bedload transport and river bed adjustment in the Lainbach catchment" within the priority programme "Fluvial Geomorphodynamics in the late Quaternary". Results of the investigations and newly developed measurement techniques were introduced to the participants during the meeting and an excursion to the nearby Lainbach River. The meeting was attended by sixty four scientists from fifteen countries. Thirty four papers were presented in sessions on bedload transport in mountain torrents, measurement techniques of solid material transport, mass movements and sediment supply, river bed adjustment and roughness characteristics of steep mountain torrents, models of bedload transport, and catastrophic flooding. From a regional perspective the majority of the contributions dealt with the Alps with a special focus on investigations carried out at the northern fringe of the Alps. Most of the papers presented were submitted for publication, and selected papers have been included in this volume. The workshop was financially supported by the Deutsche Forschungsgemeinschaft, the Commission of the European Communities (Directorate General for Science, Research and Development), the Freistaat Bayern (Ministerium fOr Unterricht, Kultur, Wissenschaft und Kunst) and the US-Army Research and Development Standardization Group. The participants and the organizers are grateful for these grants. We thank the president of COMTAG, Asher Schick, for his friendly support during the preparation and organization of the workshop. We are also very much indebted to the Kathoiische Stiftungsfachhochschule M~nchen and the Salesianer Don Bo~cos, Benediktbeuern, who opened the rooms of the monastery of Benedikbeuern for scientific sessions and social events during the conference. The organization of the meeting would not have been possible without the help of the local and regional administration, water and forest authorities. We highly appreciate this assistance. In addition, the editors thank the Springer-Verlag for the inclusion of the conference proceedings in this series and the colleagues F. Ahnert, J. Bathurst, W. Bechteler, I. Campbell, P. Carling, N.J. Clifford, S. Custer, T. Davies, A. Dittrich, R. Ferguson, K. Garleff, M. Hassan, R. Hey, H. Ibbeken, J. Karte, H. Keller, D. Knighton, J. Laronne, M. Meunier, M.D. Newson, D. Oostwoud-Wijdenes, I. Reed, K.S.Richards, A. Scheidegger and W. Symader for their valuable contributions as reviewers of the manuscripts that were submitted for this volume.

Description / Table of Contents: This book develops, for the first time, a qualitative model for the representation of spatial knowledge based only on locative relations between the objects involved. The core of this book is devoted to the study of qualitative inference methods that take into account the rich structure of space. These methods can be applied to quite a number of areas characterized by uncertain or incomplete knowledge, as for example geographic information systems, robot control, computer-aided architectural design, and natural language information systems.

Description / Table of Contents: The Himalayan chain has long been recognized as a spectacular example of the result of continent-continent collision, in this case, the result of the closure of Tethys and the subsequent collision and indentation of the Indian plate into the collage of plates or terranes that made up Central Asia some 50 Ma ago. Although the effects of that collision are recognized over a much larger region than that of the Himalaya alone, the Himalayan region forms an excellent field laboratory in which to study the, still continuing, orogenic-related processes of deformation, crustal thickening, metamorphism and melting, and foreland basin evolution. The studies that make up this volume represent all aspects of the geological sciences and have been divided into six regionally and tectonically distinct settings: Karakoram and Afghanistan; North and West Pakistan; Tethyan Himalaya; High Himalaya; Main Central Thrust Zone; Main Boundary Thrust, Lesser Himalaya and beyond.

Description / Table of Contents: Sedimentary basins with a marine connection show significant stratigraphic variations that result from eustatic sea-level fluctuation. Other key factors that control stratigraphy include the availability of sediment and the role of tectonically induced subsidence and uplift. Tectonic activity is important in most sedimentary basins as it is a causal mechanism for the production of certain regionaland local-scale sequence boundaries, generating accommodation space, altering base levels and controlling source areas. This collection of academic and industrial studies addresses the relative roles of tectonics, eustasy and sediment supply in generating stratigraphy. This volume will be of interest to petroleum geologists and researchers in sequence stratigraphy.

Description / Table of Contents: This volume is a collection of papers to celebrate the life and work of Professor lan Gass. The research themes cover many of the subjects which most interested him, especially processes operating in oceanic crust. The introductory papers examine evolution of magmas from mantle melting to eruption. A central section concerns ophiolite complexes. Several papers focus on different aspects of the Troodos ophiolite complex in Cyprus, where lan first recognized that sheeted dykes within the ophiolite sequence must have formed in an oceanic spreading environment. In addition, ophiolites ,are reviewed and examined in terms of tectonics, magmatic and mantle textures, metallogenesis and hydrothermal alteration. A further section concentrates on tectonics and the genesis of magmas associated with collision and subduction. This contrasts with continental rifting and the effects of mantle plumes. This collection of papers covers a broad range of topics from processes in the mantle to those in the oceanic crust. The volume will be of interest to all scientists concerned with igneous processes and global tectonics.

Description / Table of Contents: Owing to the maturity of exploration in the North Sea Basin, reservoir geology will increasingly focus on the exploitation of smaller and technically more demanding hydrocarbon accumulations and the need to maximize reserves from the established producing fields. More refined geological reservoir interpretation and modelling are therefore required. This book details new methods, and the improved use of existing methods in such areas as sequence stratigraphy, petrography, sedimentology, inorganic geochemistry, production logging, quantitative image analysis of pore structure, the dipmeter tool and permeability imaging; and the integration of data from a variety of these sources, including outcrop-derived data.

It was organized by Prof. R. Rummel of the Delft University of Technology and by Prof. F. Sansò of the Politecnico di Milano and was attended by 63 participants and 7 lecturers from 17 countries. The School was hosted by the International Centre of Theoretical Physics of Trieste. Satellite altimetry provides a lot of data that require more and more sophisticated models in order to be interpreted and exploited. One of the main problems related to the practical treatment of the data can be summarized as follows: oceanographers would like to ask geodesists to compute precise orbits and a precise geoid in order to put into evidence the Sea Surface Topography that can be interpreted as an oceanographic signal related to currents and to several physical parameters; on the other hand, geodesists would like to ask oceanographers to a-priori determine the Sea Surface Topography, in order to be able to extract from the altimeter data the geoid and the orbit errors to be used in the gravity field modelling. The solution to this dilemma can only be found in a cooperative frame. An integrated model to be used for a single-step treatment of altimetry is probably far to be defined, so at present geodesists and oceanographers must cooperate to obtain step-wise and iterative modelling of the gravity field and of the oceanographic phenomena. This is precisely the reason why the school on Satellite Altimetry was organized on an interdisciplinary basis...

Description / Table of Contents: PREFACE Turbidity currents have been comprehensively studied in the past although much remains unknown about both their flow characteristics and resultant sedimentary deposits. Much of this uncertainty arises from the catastrophic nature of their formation which makes them difficult to study in the environment, and has resulted in the majority of studies being experimental or theoretical. Experiments have shown that reversals in the flow of density currents can be associated with the generation of internal solitary waves. This is in contrast to the belief held by many workers that the reversal of a turbidity current simply generates an identical flow travelling in the opposite direction. This book arose from the need for a detailed experimental study to examine the effects and to consider the consequences of density current reversals from a variety of obstructions to their flow. The first part of this book comprises a detailed review of literature covering the fluid dynamics and sedimentology relevant to the experimental study (chapter one). Chapter two presents the results from the comprehensive experimental programme which are discussed and compared with appropiate theoretical hypotheses. This permits the synthesis of a model for the general features of flows that result from the incidence of density currents upon obstructions to the flow. The application of this model to both modern and ancient turbidite systems is then discussed in chapter three. This book is suitable for earth scientists with an interest in the dynamics of turbidity currents. In addition, workers from other fields such as applied maths, meteorology and engineering who have an interest in density currents and bores in practical situations may find it useful...

Description / Table of Contents: PREFACE Sedimentation as a Three-Component System describes the most common styles of deposition in marine environments as they relate to sediment composition. Three components, organic matter, carbonate, and siliciclastic sediment, may settle concurrently, but at different rates, intermixing on the sea floor to form a particular sediment composition. A change in the flux of one component is capable of relatively diluting or concentrating the other two components, which can be expressed in the characteristic ratio of organic carbon to carbonate in the resulting sediment. The basic concept of this book is to address organic carbon-carbonate associations in terms of depositional inputs and time spans. In addition, the three-component system describes organic carbon changes related to major facies transitions. Examples include models of the genesis of carbonaceous sediments, with their various laminated to bioturbated lithotypes, and numerical organic carbon prediction. I hope that this book will encourage stimulating discussions and promote a new approach to quantitative stratigraphy...

Description / Table of Contents: The present interest in sediments which are rich in organic matter results not only from their economic significance as potential oil and gas source rocks, but also from the fact that their deposition is the result of special environments. Subtle changes in the environmental conditions may result in great variations in the geochemical and petrographical characteristics of the organic matter. Therefore, the study of organic matter-rich sediments can provide a key to past sedimentary conditions. In addition, the elucidation of the depositional controls is of importance for oil and gas exploration strategies, for which the knowledge of source rock distribution and quality is critical. Furthermore, organic matter reacts extremely sensitive to changes in temperature during burial. The result of this sensitivity is the generation of volatile products such as carbon dioxide, water, nitrogen, oil and gas and a reorganization of the solid organic residue. Some of these changes are quantified as maturity parameters which can be used as calibration tools in basin modelling, i.e., in the modelling of temperature histories of sedimentary basins. The use of maturity parameters and other organic matter characteristics as indicators for diagenetic conditions and depositional processes is, however, restricted, if analyses are performed on outcrop samples, because weathering also affects organic matter.

Description / Table of Contents: The Third International Symposium on Large Spatial Databases (SSD '93) was held at the National University of Singapore in June 1993. The previous meetings of the series were at Sanata Barbara (1989) and Zurich (1991). The meetings are planned as a forum for researchers and practitioners specializing in database theory for and advanced applications of Spatial Information Systems. This volume constitutes the proceedings of the symposium. It contains 25 selected papersand three keynotes papers: "Spatial data management in database systems: research directions" (W. Kim), "From extensible databases to interoperability between multiple databases and GIS applications" (H.-J. Schek), and "The SEQUOIA 2000 project" (M. Stonebraker). The selectedpapers are collected into sections on: data modeling, spatial indexing, indexing mechanisms, handling of raster and vector data, spatial database systems, topology, storage management, query retrieval,knowledge engineering in SDS, and 3-dimensional data handling.

Description / Table of Contents: INTRODUCTION "The geological history, as expressed by the stratigraphic column, is basically composed of cycles of sedimentation, stratification and magmatism which correlate with relative changes in sea level determined in turn by different types of crustal movements. The classical sequence of stages "transgression - inundation - differentiation - regression - emergence" is believed to reflect the deformation phases of a geotectonic cycle" (Wezel,1988: p.37). The concept of geotectonic cycle is fundamental in geology because it links tectonics with sedimentary processes. According to Wezel (1988) the geotectonic cycle is an expression of cyclic variations in the behavior of the crust; more precisely,it is a geodynamic response to the Earth's variations in the rate of rotation (Mörner,19869 Whyte,1977~ Carey,1976).Based on a global analysis of geotectonic data, synchronous episodes of intense global swelling, governed by cyclically ordered diastrophic processes, were identified (Wezel,1985;1988). The process leading to these swells was termed krikogenesis (Wezel, 1988).It basically consists of not steady, localized, migratory vertical movements linked to mantle diapirism and concentrated in single zones.The overlying crust adjusts itself to mantle motions induced by krikogenesis, with the formation of transient troughs and swells ('touche-de-piano' tectonics).This mechanism was individuated in several areas (Wezel,1988). The history of the Earth is described by six episodes that repeat in the same way in the course of geological time.Their duration progressively decreases:the first cycle has a duration of about 200 million years, the following,younger cycles lasted 150, 115, 65, A5 and 20 m.y. ...

Description / Table of Contents: INTRODUCTION The study is essentially empirical, since it portrays and appraises two different water management systems, and relates them to one another. Yet the analysis has also been made with definite research aims in mind. Its focus has been narrowed down to the environmental assessment of urban water management systems in arid and semi-arid regions, especially with an eye to deal with information problems in the Developing World. The study addresses a set of very critical issues of global concern, and, thus, delineates a crucial topic for international research. The fact that a wide range of critical issues usually complicates and aggravates the given problem setting provides the comparative analysis with a special practical incentive to explore the opportunities for joint strategies and comprehensive solutions. However, the complexities involved between water management and the environment and the relative lack of a joint theory in that field pose certain difficulties to such an undertaking. In order to fully appreciate the underlying purpose of the study and the scope of its implications, the various facets of the problem setting and the essential ingredients of the general line of approach have first to be unravelled and expounded at some length. Above all, it needs to be shown how these facets combine to produce the complex, burning issues which in turn seem to, both in theory and practice, require correspondingly intricate, strategic approaches for their solutions...

Description / Table of Contents: PREFACE Some of the major ecological and social problems of the present and future are the production, treatment, and disposal of anthropogenic wastes. Iaais is equally true for sparsely and densely populated industrial areas, including large countries in which sites for waste disposal would seem to be readily available. Especially nonradioactive hazardous wastes with their long-term toxicity need to be isolated from the biosphere just as effectively as radioactive substances. The long-term safety required of waste disposal sites can only be assured under specific geological and mineralogical conditions in certain parts of the lithosphere (underground repositories). The subjects related to the production, avoidance, treatment, and disposal of anthropogenic wastes cover a range of knowledge encompassing the natural sciences, engineering, medicine, and law. This work presents some fundamental situations and problems conceming the disposal of toxic hazardous wastes which have been dealt with in several research projects. The individual chapters are related scientifically. Long-term, effective solutions to our waste problems can only be found when interrelationships and possible future developments are considered. Only the current status of this rapidly developing field can be discussed here. The individual chapters contain scientifically founded data and observations. Other aspects for which there are still controversial opinions and arguments are also discussed, which should stimulate further thought. Further developments and scientific advances can only be achieved by constantly challenging previous theories, and not through static observation and narrow-mindedness. The most extensive quantification possible of the problems related to disposal of hazardous wastes is an essential aim of our work. This not only involves calculating the volume of waste and available repository space, but also compiling data on the long-term effects and the safe, long-term isolation of anthropogenic wastes from the biosphere. A simple description of conditions and processes without using concrete data, which is still widespread, is rejected since it frequently leads to pure speculation. The scientific fundamentals and results presented in this work are of general validity for many questions concerning waste disposal. One example is the amount of waste produced annually in Germany, in which toxic, hazardous wastes play a major role. FoIlowing this train of thought, available data are used to show how limited the possibilities are for the long-term safe underground deposition of hazardous wastes with respect to the current quantities of waste. Of utmost importance is information on the 10ng-term effects of toxic wastes, as well as criteria which have to be considered with respect to the long-term safe deposition of hazardous waste. The natural chemical cycles and material transport in the various zones of the earth are the focus of interest here. They are the scientific basis for assessing every repository for anthropogenic wastes in geological systems. Therefore the significance of material transport and geochemical cycles is emphasized regarding all questions concerning the long-term safety of repositories on the earth's surface and in the lithosphere. Thus, our concept for the scientific evaluation of the long-term safety of underground repositories in geological systems differs from all other models presently under discussion in Germany. In this work, marine evaporites are discussed with respect to the underground deposition of hazardous wastes and the long-term safety of underground repositories in salt rocks. The isolation of hazardous materials from the biosphere can above all be influenced by fluid phases. Fluid phases can mobilize and transport hazardous materials through rocks in the biosphere. This is true, without exception, for all magmatic, sedimentary, and metamorphic rocks, and for marine evaporites, too! In Germany evaporites have commonly been considered to be completely impermeable with respect to fluid phases (solutions and gases). This erroneous view stems from a complete lack of knowledge or misestimation of the dynamic evolution of the composition of evaporite bodies. Unfortunately, this is still true today for parts of some state agencies which deal with repositories. However, all observations of evaporite bodies made over the last more than 100 years have clearly shown that under certain conditions fluid and gaseous components are mobile in evaporites as well. Solutions in marine evaporites have been the object of personal interest and scientific research of A.G. Herrmann for 40 years. The occurrence and formation of salt solutions in the various salt mining districts of Germany are presently being restudied and reevaluated on an extended scientific basis (e.g., v. BORSTEL 1992). A presentation of the current knowledge on salt solutions is beyond the scope of this publication. However, in the interest of continuing research a research project proposed by A.G. Herrmann (1987b) will be introduced here. The direct quantitative analysis of the chemical composition (quatemary and quinary systems) of small fluid inclusions in rocks of the salt deposits of Hessen and Niedersachsen are the primary focus of this project. Information important to fundamental research on the formation and alteration of salt rocks and on the long-term safety of underground repositories should be gained from these studies (e.g., HERRMANN & v. BORSTEL 1991). In addition to salt solutions, gases are also fluid components which occur in practically all marine evaporite deposits. Hence, both salt solutions and gases must be carefully considered when planning underground repositories in an evaporite body and evaluating their long-term safety. This publication contains an up-to-date overview of the gas occurrences in the marine evaporites of Central Europe. Despite previous studies, there is still a considerable deficit in scientific information regarding the distribution and formation of gases in the evaporites occurring in Germany. A detailed research program on the geochemical relationships involving the formation of evaporites and gases will draw attention to this situation. One aspect must be emphasized in the planning and construction of repositories for anthropogenic wastes: their long-term safety. This publication deals precisely with this subject, and in Part III of this work we will present the concept that we have developed. This concept is based on the fact that evaporite bodies are subject to a dynamic evolution and that the chemical and mineralogical composition provides important information on the effect of fluid phases on salt rocks. Previous works contain the testing of methods and presented initial results using the Gorleben salt dome as an example. However, we are just at the beginning of our research project on the long-term safety of underground repositories (e.g., HERRMANN & KNIPPING 1989, HERRMANN 1992). The information contained in this publication is based on years of experience in evaporite research and underground repositories for anthropogenic wastes. Examples are presented which can be applied to similar situations and problems in other countries. Waste disposal is not just a national problem, it has long become an international one for all types of anthropogenic wastes...

Description / Table of Contents: Image sequence processing is becoming a tremendous tool to analyze spatio-temporal data in all areas of natural science. It is the key to studythe dynamics of of complex scientific phenomena. Methods from computer science and the field of application are merged establishing new interdisciplinary research areas. This monograph emerged from scientific applications and thus is an example for such an interdisciplinaryapproach. It is addressed both to computer scientists and to researchers from other fields who are applying methods of computer vision. The results presented are mostly from environmental physics (oceanography) but they will be illuminating and helpful for researchers applying similar methods in other areas.

Description / Table of Contents: Since the publication of Geological Applications of Wireline Logs in 1990, there have been many new developments in the technology of wireline logging tools and in the correlation and interpretation of downhole measurements. This volume provides extensive documentation of the diversity of geological and geophysical problems which can be addressed by wireline log data. High-density/high-resolution log measurements now appear to be an integral part of the characterization of petroleum reservoirs; there is increasing interest in the use of logs for quantitative determinations of the physical properties of rocks; there is also abundant evidence for the importance of integrating geological and geophysical data are different scales and the potential benefits of multidisciplinary approaches to problem solving. The editors hope that Geological Applications of Wireline Logs II will, in common with the earlier volume, act as a milestone in its field.

Description / Table of Contents: "...represents a timely and welcome contribution to the field as it comprises semi-review articles dealing with magma generation and break-up processes, as well as syntheses from selected examples of CFB provinces. In addition there are several case studies (both geochemical and geophysical) which examine specific issues in detail. Even in isolation many of these articles are exceptionally useful, either as distillations of current thinking, or as new contributions of ideas and~or data. Together, however, they combine to create a comprehensive volume covering much of our present understanding.., of the causal relationships between lithospheric extension, rifting, thermal anomalies and magmatism. 'Janet Hergt in Chemical Geology, vol. 109, p356 '...should be within reach of all geoscientists seriously interested in continental flood volcanism and mechanisms of continental break-up. It provides a fascinating picture of the current state of knowledge of continental break-up on a global scale and highlights the complexity of the driving forces of break-up and the origins of associated basaltic rocks... In general, this is an important book which provides a solid foundation for developing understanding of modern continental rift tectonics and for the interpretation of continental rift geology and magmatism in the geological record. Every university geology library should buy it.' G. Wheller in Australian Geologist No 88, p41 '...breadth of subject matter, the diversity of the authors and the speed of publication all conspire to make this an excellent 'research in progress' volume. This is not a collection of similar papers reporting a consensual view, but a far more useful picture of the state of the art. In particular, it covers both the well-known examples of continent break-up apparently related to 'plume' magmatism, as well as examples where break-up manifestly has nothing to do with hot upwellings... This book should be in every library of Earth Science.' D. Pyle in Geological Magazine, vol. 131, p732 '...provides a wealth of information and stimulating ideas for geologists interested in breakup tectonics, magmatism and stratigraphy.., should be a required acquisition for university and research libraries.' Warren Manspeizer in Earth Science Reviews, vol. 35, p327

Description / Table of Contents: Conventional studies of oceanic structure and evolution are inevitably hampered by the difficulties with sampling the crust in the third dimension. Subsurface studies with deep seismic techniques provide some measure of understanding below the seafloor. Ophiolite studies, however, can provide a vast body of knowledge with regard to the deeper structure and crustal compositions, which is unattainable in the deep sea. In turn, many of the recent regional and detailed structures identified at mid-ocean spreading systems such as ridge segmentation patterns and ridge axis discontinuities, now form a significant contribution to recent studies of ophiolite complexes. The book will be of interest to academics from undergraduates upwards and also to industrial researchers concerned with metal sulphide and platinum group element deposits. Cover illustration: Deep-tow sidescan sonograph of the axial floor of the Mid-Atlantic Ridge around 24°N. Data were recorded using the IOSDL Towed Ocean Bottom Instrument. View is 6×8 km in a water depth of around 3500 m. Cratered seamounts, freshly mounded pillow constructs and linear fault scarps are clearly imaged. These currently active ridge processes compare directly with their ancient analogues discussed in this publication.

Description / Table of Contents: This volume represents a multi-disciplinary research effort into the development of basins of carboniferous to Tertiary age on the North West Seaboard of the British Isles and includes 30 contributions from oil company personnel, university research groups, consultants and geological surveys. The series of basins which stretches from west of Shetland to the west coast of Ireland constitutes one of the largest basin systems in Europe. Regions covered in this volume include the Hebrides, off-shore N Ireland/SW Scotland, onshore N Ireland, the Porcupine Basin and the Celtic Seas. All of these regions are attracting the attention of hydrocarbon exploration programmes and have already seen drilling activity. This interest is reflected in papers on basin burial and thermal histories, source rock potential, depositional models for reservoir rocks and diagenetic studies. Beyond the British Isles, papers are included on the NE Atlantic Seaway and the Canadian Margin, and several authors make comparisons between the Canadian and European Margins. The models and data reported in the volume will be of value to all concerned with an area which has an important future both in hydrocarbon exploration and in fundamental research into basin evolution.

Description / Table of Contents: PREFACE The emergence of new information from drilling in deep-sea and coastal areas and the surfacing of the plate tectonics theory probably had the greatest impacts in recent decades on the highly accelerated growth of knowledge regarding the evolution of sediments and sedimentary rocks. Studies in recent years have also provided new insights on global sedimentary processes, and isotopic tools in many ways have enhanced our knowledge and have provided even an unexpected added dimension to the mechanisms of some specific processes. Many different uses of isotopic tools in studies of sedimentary processes can be found in the literature, but the information is highly scattered in the vast field of sedimentology. The disseminated state of existing isotopic knowledge on sedimentary systems has undoubtedly deprived many practitioners in the field to fully appreciate the benefits and limitations, and even the apparent confusion, concerning the use of isotopic tools. We have endeavored here to bring together discussions on some major sedimentary systems in the sedimentary cycle and to analyze them according to isotopic evidence. To accomplish such a task required contributions from many individuals. We were fortunate to have friends who accepted to share our goals. We most sincerely thank all the contributors to this book and deeply appreciate their patience and fortitude despite our undue demands on them to reach our objectives...

Description / Table of Contents: PREFACE The papers contained in the present volume were prepared from the contributions presented during an international Advanced Workshop held in Santander, Cantabria, Spain between 1-5 November 1989. The workshop was a joint activity of the Working Group on Geology and Land-Use Planning (program "Geology and Environment", UNESCO), the Commission on Applied Quaternary Research (INQUA), the Sub-Commission on Maps of Environmental Geology (Commission of the Geological Map of the World) and the Grupo Españiol de Geología Ambiental y Ordenación del Territorio (Spanish Association for Environmental Geology and Land-Use Planning). The aims of the meeting were to discuss a series of topics in which the four participating scientific bodies share an interest, to analyze the existing problems and trends and to identify certain lines along which work and/or actions will be particularly necessary in the near future. It was expected that the discussions and the conclusions of the meeting would provide useful guidelines for earth scientists working on environmental problems and for other professionals and officials who deal with environmental analysis, planning and management, either on a scientific basis or in a decision-making capacity...

Description / Table of Contents: During the 1980s the increasing availability of seismic reflection data prompted an upsurge of interest in extensional tectonics, early work concentrating on ‘listric’ thrust-belt type models and the concepts of section balancing. However, earthquake seismology and detailed fault studies have shown recently that faults involved in crustal extension may be essentially planar. This volume concerns the geological setting and interpretation of both listric and planar normal faults. Normal faults are of particular importance in UK hydrocarbon exploration as they are directly or indirectly responsible for the majority of the pre-Tertiary oil and gas accumulations in the North Sea. As the economic size of fields reduces, the modern geologist will require an improved understanding of the origins, geometry and sealing capabilities of these faults. The volume is divided into four sections, dealing with: the geometry and kinematics of large-scale, crustal-stretching faults which typically delimit major hydrocarbon accumulations; case studies ranging from the small-scale fractures associated with the movement of salt to the large-scale intra-plate kinematics of whole fault arrays; studies of detailed displacement patterns shown by individual faults and small fault arrays; and modelling studies of normal fault geometry. The editors believe that this volume will clarify the circumstances in which the diverse models of normal fault geometry might be applicable and thus provide a useful source of reference for both industry- and academia-based research workers. Another volume on extensional tectonics? Yes, but not only is this one very nicely put together, it is also very timely … The editors have wisely placed the emphasis on observations and data … Roberts et al. deserve a great deal of credit for the very high standard of presentation. Most of the contributions contain sensible stuff that is clearly written. Illustrations are excellent … and there are hardly any typos … Ican thoroughly recommend this book to both libraries and individuals.

Description / Table of Contents: PREFACE The application of thermal analysis to earth science has a long history. This is evidenced by the extensive coverages by Mackenzie (1957, 1970), Langier-Kuzniarowa (1967), Schultze (1971), Liptay (t973), Smykatz- Kloss (1974), Todor (1976) and Heide (1982). The chief thermal method has been differential thermal analysis (DTA). Additionally, thermogravimetry (TG; Duval, 1963; Keattch, 1969; Earnest, 1988) and thermodilatometry (Schomburg & Strörr, 1984) have gained some importance. All these methods are still widely ltsed. But recently several new techniques have gained attention, such as thermomagnetometry, thermomechanical analysis and thermosonimetry. Improved equipment made possible the application of thermal methods to problems in thermodynamics and kinetics (e.g. by means of differential scanning calorimetry, DSC). This progress in the construction of new instruments as well as the combination of existing methods to enable simultaneous determinations (e.g. TG/DTA; TG/IR spectroscopy; DTA/mass spectrometry; DTA/microscopy; high-pressure DTA) have led to a resurgence in the use and application of thermal analysis in the earth sciences. Here the applications cover such diverse areas as the examination of individual minerals, mineral mixtures, rocks, soils, ceramics, cements, raw materials as well as their industrial evaluation, performance assessment and quality control. In the field of solid fossil fuels thermal determinations range from proximate analysis of inorganic constituents and the measurement of calorific values to the assessment of the environmental aspects of fly ashes and mineral residues. To support this tendency, the International Confederation for Thermal Analysis (ICTA) has recently founded a "Committee for Thermal Analysis in Geosciences". The aim of this committee shall be to discuss, improve and distribute the knowledge about the possibilities of solving geoscientific questions by means of thermal analytic methods...
