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.

Rock Physics & Geomechanics in the Study of Reservoir & Repositories - Special Publication no 284

Rock Physics & Geomechanics in the Study of Reservoir & Repositories - Special Publication no 284Publisher: Geological Society of London ISBN: 1862392307 edition 2007 PDF 232 pages 6,6 mb

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.

Global Neoproterozoic Petroleum Systems: The Emerging Potential in North Africa - Special Publication 326

Global Neoproterozoic Petroleum Systems: The Emerging Potential in North Africa - Special Publication 326Publisher: Geological Society of London ISBN: 1862392870 edition 2009 PDF 320 pages 14,3 mb

Worldwide, Neoproterozoic successions are major hydrocarbon producers. In North Africa, large basins with significant surface outcrops and thick sedimentary fills are widespread. These basins are now emerging as potential sources of hydrocarbons and are attracting interest both from geological researchers and the oil and gas industry.

Earth Accretionary Systems in Space and Time - Special Publication no 318

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 Purposes

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 Systems

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.
