Product Description

This volume contains a series of papers on a wide range of aspects of the early development of the Earth in the first 2000 Ma of Earth’s history, including geophysics, structure and tectonics, atmosphere, origin of life, biosphere, deep mantle geochemistry, early oceans, microbial ecology, the aim being to facilitate discussion and understanding of this area of research. The book is divided into three parts: (1) Geophysical and Petrological Constraints on Archaean Lithosphere: These papers highlight differences in structure and composition of Archaean and post-Archaean lithosphere, with contributions from seismologists, petrologists, and geochemists. Seismic evidence for the formation and evolution of cratons is presented. Shear wave splitting results, petrologic data and crustal deformation fabrics are used to characterize variations of anisotropy in order to investigate the coupling and decoupling of the crust and upper mantle beneath cratons, isotopic data from large cratons suggesting that the lithospheric mantle is the same age as the overlying crust, provide further constraints on the modification of cratonic roots with time. (2) Models of Cratonic Evolution and Modification: These papers focus on global and regional models of cratonic accretion based on evidence from the rock record. Numerical models of cratonic rock both in normal mantle flow and in the presence of plums suggest that cratons decrease in size by lateral erosion rather than by thinning. (3) Constraints on the Archaean Environment: These papers are concerned with the physical, chemical and biological controls on Earth’s surface environment in the late Hadean and the Archaean. Archaean strata record the early biogenic controls on the carbon cycle, and shift to an oxygen-rich atmosphere. The timing of hydrogen loss, carbon-dioxide build-up, the appearance of life, and the origins of photosynthesis are all controversial topics discussed here. Subjects covered include the chemical and biological controls on the atmospheric and oceans, early controls on the carbon cycle and photosynthesis, petrologic, isotopic, tectonic and seismic evidence for the composition and structure of Archaean lithosphere.

Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives

Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives Publisher: Geological Society of London Pages: 424 2003 ISBN 1862391173 PDF 35 MB

The motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes. They are a mixture of review papers on selected topics in the field of structural geology and tectonics and papers on current issues and new techniques and are grouped into four themes: The effect of fluids on deformation; The interpretation of Microstructures and textures; Deformation mechanisms and rheology of crust and upper mantle minerals; Crust and lithosphere tectonics.

Coastal Processes with Engineering Applications

Coastal Processes with Engineering ApplicationsPublisher: Cambridge University 488 pages March 25, 2004 ISBN 0521602750 PDF 8 MB

The world's coastlines, dividing land from sea, are geological environments that are unique in their composition and the physical processes affecting them. At the dynamically active intersection of land and the oceans, humans have been building structures throughout history. Initially used for naval and commercial purposes, more recently recreation and tourism have increased activity in the coastal zone dramatically. Shoreline development is now causing a significant conflict with natural coastal processes. This text on coastal engineering will help the reader understand these coastal processes and develop strategies to cope effectively with shoreline erosion. The book is organized in four parts: (1) an overview of coastal engineering, using case studies to illustrate problems; (2) hydrodynamics of the coastal zone, reviewing storm surges, water waves, and low frequency motions within the nearshore and surf zone; (3) coastal responses including equilibrium beach profiles and sediment transport; (4) applications such as erosion mitigation, beach nourishment, coastal armoring, tidal inlets, and shoreline management.

Noting a marked lack of comprehensiveness and/or contemporaneity among typical reference works on chemical etymology, as well as a somewhat spotty coverage of chemical terms and their etymology in comprehensive dictionaries and textbooks the author decided to write an up-to-date desk reference on chemical etymology which would satisfy the needs of casual readers as well as those of more demanding users of etymological lore. Characteristic user-friendly features of the present work include avoidance of cumbersome abbreviations, avoidance of entries in foreign alphabets, and a broad coverage of all chemical disciplines including mineralogy. Biological, medical, geological, physical and mathematical terms are only considered where they appear of interest to mainstream chemists.This book does not provide definitions of terms (unless required in the etymological context) nor guidance as to the timeliness of different nomenclature systems. The typical user will from the outset be well aware of the exact meaning of the terms he or she focuses on and only require the etymological background to be used. Examples of sources which have been drawn upon in the preparation of this book, apart from the extremely useful Internet resource Google, are listed, but an exhausting enumeration would be tiresome and impractical.

Microtectonics deals with the interpretation of microstructures, small-scale deformation structures in rocks that yield abundant information on the history and type of deformation and metamorphism. The results are used by geologists to obtain data for large-scale geological interpretations. This advanced textbook treats common microstructures such as foliations, porphyroblasts, veins, fringes and shear sense indicators. The book mainly focusses on optical microscopy as a tool to study microstructures, but also describes other techniques such as EBSD and tomography. Many photographs and explanatory drawings clarify the text. The new edition, substantially revised throughout and extended, features two new chapters (primary structures and experimental microstructures), 68 new figures, more than 800 new references.

The Internal Structure of Fault Zones: Implications for Mechanical and Fluid-Flow Properties

The Internal Structure of Fault Zones: Implications for Mechanical and Fluid-Flow PropertiesPublisher: Geological Society of London ISBN: 1862392536 edition 2008 PDF 376 pages 13 mb

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.

Channel Flow, Ductile Extrusion & Exhumation in Continental Collision Zones - Special Publication no 268

Channel Flow, Ductile Extrusion & Exhumation in Continental Collision Zones - Special Publication no 268Publisher: Geological Society of London ISBN: 1862392099 edition 2006 PDF 630 pages 61,9 mb

This collection of 27 review and research papers provides an overview of the geodynamic concepts of channel flow and ductile extrusion in continental collision zones. The focal point for this volume is the proposal that the middle or lower crust acts as a ductile, partially molten channel flowing out from beneath areas of over-thickened crust, such as the Tibetan plateau, towards the topographic surface at plateau margins. This controversial proposal explains many features related to the geodynamic evolution of the plateau and, for example, extrusion and exhumation of the crystalline core of the Himalayan mountain chain to the south. In this volume thermal-mechanical models for channel flow, extrusion and exhumation are presented, and geological and geophysical evidence both for and against the applicability of such models to the Himalayan-Tibetan Plateau system, as well as older continental collision zones such as the Hellenides, the Appalachians and the Canadian Cordillera, are discussed.

Earth Accretionary Systems in Space and Time - Special Publication no 318Geological Society of London ISBN: 1862392781 2009-07-15 PDF 415 pages 9 Mb

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.

Aggregates: Sand, Gravel and Crushed Rock Aggregates for Construction PurposesGeological Society of London 2001 ISBN 1862390797 360 Pages 11 MB




In 1985, the Geological Society published Aggregates as the first volume in its Engineering Geology Special Publication series. It met with immediate acclaim, being awarded the Brewis Trophy by SAGA in 1986 and drawing the following review from the Canadian Geotechnical Journal in 1988: This book is in general a well-researched, informative and useful guide to the location, sampling and testing of aggregates. If your work involves the use of aggregates, buy this book and read no further; this volume will be an essential and valuable reference that you will use for many years. In 1989, the working party whose work had resulted in the publication of Aggregates was reconvened to revise, update and extend their report. Each chapter was reviewed by independent referees. The second and greatly improved edition, published in 1993 and reprinted in 1998, represented the distillation of a vast body of knowledge and experience held not only by the members of the working party, but also by many international experts, scientists and engineers who contributed as reviewers, referees and corresponding authors.

Structure and Emplacement of High-Level Magmatic SystemsGeological Society of London September 15, 2008 English ISBN: 1862392560 234 pages PDF 10.13 MB

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 origin 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.

Palaeobiogeography and Biodiversity Change: The Ordovician and Mesozoic-Cenozoic Radiati

Palaeobiogeography and Biodiversity Change: The Ordovician and Mesozoic-Cenozoic Radiations Geological Society of London August 1, 2002 ISBN-10: 1862391068 216 pages PDF 16.8 mb

The study of biodiversity through geological time provides important information for the understanding of diversity patterns at the present day. Hitherto, much effort has been paid to studying the mass extinctions of the Phanerozoic but the research emphasis has now changed to focus on what occurred between these spectacular catastrophic events. After the Cambrian 'explosion' of marine organisms with readily preservable skeletons, there have been two intervals when life radiated dramatically - the Ordovician Period, and the mid-Mesozoic-Cenozoic eras. These intervals saw a fundamental reoganization of biodiversity on a hierarchy of biogeographical scales. The size of these diversity increases and their probable causes are topics of intense debate, and there is an intriguing link between the dispersal of continents, changing climates and the proliferation of life.

ANALOGUE AND NUMERICAL MODELLING OF CRUSTAL-SCALE PROCESSES

ANALOGUE AND NUMERICAL MODELLING OF CRUSTAL-SCALE PROCESSES Publisher: Geological Society of London ISBN: 1862391912 edition 2006 PDF 439 pages 50,5 mb

The crust of the Earth records the deformational processes of the inner Earth and the influence of the overlying atmosphere. The state of the Earth's crust at any time is therefore the result of internal and external processes, which occur on different time and spatial scales. In recent years important steps forward in the understanding of such complex processes have been made by integrating theory and observations with experimental and computer models. This volume presents state-of-the-art analogue and numerical models of processes that alter the Earth's crust. It shows the application of models in a broad range of geological problems with careful documentation of the modelling approach used. This volume contains contributions on analogue and numerical sandbox models, models of orogenic processes, models of sedimentary basins, models of surface processes and deformation, and models of faults and fluid flow.

Natural and Anthropogenic Hazards in Karst Areas: Recognition, Analysis and Mitigation

Natural and Anthropogenic Hazards in Karst Areas: Recognition, Analysis and Mitigation Publisher: Geological Society of London ISBN: 1862392242 edition 2007 PDF 202 pages 29,2 mb

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.

Within the last 25 years there has been a dramatic increasein our knowledge of the fossil record of Antarctica. Improvedaccess to the remotest parts of the continent, the advent ofoffshore drilling and intensive study of early expedition collectionshave all led to the accumulation of a vast amount of data thatstretches back nearly 600 Ma to the beginning of the Cambrianperiod. No longer can Antarctica be dismissed from our viewof the history of life on earth simply because so little isknown about it; it is fast becoming another crucial referencepoint for global palaeontological syntheses.If, today we have an image of Antarctica as a remote, inhospitablecontinent that supports little life, we now know that such aview cannot be projected back indefinitely through time. Abundantplant and animal fossils from a variety of periods point tomuch more benign climates and immediately raise a series ofinterconnected questions: where did such organisms come from,how long did they persist, and precisely when (and how) didthey become extinct? Can our most southerly continent throwfurther light on the long-term role of climate in driving evolutionarytrends (e.g. Valentine 1967; Vrba 1985)?It was with points such as these in mind that a mixed groupof palaeontologists, biologists, geologists and geophysicistsgathered together for an international discussion meeting onthe ‘Origins and evolution of the Antarctic biota’at the Geological Society, London on 24 and 25 May 1988

C. Harris, J. B. Murton "Cryospheric Systems: Glaciers And Permafrost"Geological Society of London English 2005 ISBN: 1862391750 161 pages PDF 26 MB

The introduction of the term periglacial by Lozinski in 1909 to describe the cold-climate conditions in the zone adjacent to, but beyond, the Pleistocene glaciers encouraged the separate development of geocryological and glaciological research. Geological and geomorphological processes at the interface between glaciers and permafrost have, as a result, been given less attention than they warrant, and the influence of one on the other has in many respects been neglected. This book includes a collection of papers that emphasize glacier-permafrost interactions. Papers consider permafrost and its influence on glacitectonic processes, glacial meltwater systems and ground-ice development in proglacial and ice-marginal environments. In addition, recent research findings are reported on paraglacial processes, permafrost evolution, rock glaciers, the formation of ice-wedge casts and periglacial slope evolution.It is hoped that this book will stimulate interest in the interface between glacial and periglacial systems, and encourage further collaborative research involving glaciologists and glacial geologists on the one hand, and geocryologists and permafrost scientists on the other.

This book discusses the current state of research on the geology of the area between North and South America, with a focus on the origin of the Caribbean Plate. Prevailing understanding is that the Caribbean Plate formed in the Pacific and migrated between the Americas. According to this model, the plate comprises oceanic and volcanic arc rocks. An alternative interpretation considers that the plate formed in place and includes extended continental crust. Hybrids of these ideas also exist.The papers in this volume provide regional overviews, discussions of the origins of the Caribbean Plate, and consider aspects of local geology arranged in a circum-Caribbean tour and ending in the plate interior.They address tectonics, igneous and metamorphic geology, stratigraphy and palaeontology. The objective of this wide variety of topics is to facilitate debate.The Geological Society of London

The Palaeoproterozoic era (2500-1600 Ma) is 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. The volume is useful as a reference book for students and professional geoscientists interested in this important period of global evolution.
