Download or read book Faulting in Brittle Rocks written by Georg Mandl and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction into the mechanics of faulting in the brittle crust of the Earth. It developed from my annual two-semester course on tectono mechanics for graduate students of engineering geology and of rock engineering at the Technical University of Graz (Austria). In this course, it is not my task to present a broad exposition and geometrical description of geological structures, but rather to focus on the mechanical processes that produce the structures. Although this was also the aim of my former book "Mechanics of Tectonic Faulting - Models and Basic Concepts" (1988, Elsevier), henceforth referred to as MTF, the present book is different in organisation and content, in order to meet the requirements of the courses and to include more recent developments. Instead of following the traditional subdivision into extensional, compressional and strike-slip faulting, the presentation focuses on mechanical aspects of tectonic faulting that are common to various, or even all types of tectonic faults in the brittle regime. In this way, geometrically disparate or dissimilar fault structures may be revealed as closely related by the underlying mechanical process, and complex structures may be better understood. It may be useful to indicate how the chapters in the book are organised. The first three chapters are an introduction to rock mechanics, tailored to applications in geology. It also presents the extremely useful graphical method of Mohr's stress circle, which is freely used throughout the book to keep the mathematics to an absolute minimum.

Download or read book Mechanics of Tectonic Faulting written by Georg Mandl and published by Elsevier Publishing Company. This book was released on 1988 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series, under the editorship of Professor H.J. Zwart, will deal with all topics within this field, such as: micro structures, large scale tectonics, experimental structural geology, fabrics, rock mechanics, and modelling in structural geology. The aim is to publish advanced level reference books to provide state-of-the-art reviews of these and other aspects of structural geology. This series will be of value to researchers and professionals in structural geology, rock mechanics, petroleum geology and tectonophysics.This first volume in the series deals with the mechanics of tectonic faulting and its central theme is the formation of faults in the tectonic stress field and the interaction between faults and stresses. The author, Dr. G. Mandl, was one of the top research people with Shell International Research. Part I of the book deals with the mechanical genesis of general fault features, such as fault shape and antithetic, precursory and secondary faulting and elaborates on these more general aspects within the context of specific tectono-mechanical models for extensional faulting and thrusting. Besides critical reviews, Part I contains a number of new or hitherto unpublished results, in particular on model experiments and numerical analyses. The central chapter of Part II presents a full introduction into mechanical theory and rock plasticity - the theory most adequate to tectonic faulting and therefore forming the backbone of the book. Besides presentations of basic concepts of stress and strain, special chapters are devoted to poro-elasticity and fluid flow through porous rocks. This branch of geomechanics requires a multidisciplinary approach that combines continuum mechanics, rock mechanics and structural geology, and applies theoretical, numerical and experimental methods, together with the study of field cases. The book has evolved from such multidisciplinary research and is written for structural geologists, petroleum geologists, engineering geologists, rock engineers and geophysicists whose work demands a similar approach. In addition, the book is intended to encourage mechanical engineers and even mathematicians to enter the fascinating and in parts still untilled fields of tectono-mechanical processes in the Earth's crust. The book is richly illustrated by drawings, photographs and reproductions of seismic records.

Book excerpt: This Volume brings together twelve contributions to a symposium held in hon our of GEORG MANDL at the University of Graz, Austria on December 1-2, 1995, in the year of his 70th anniversary. It is a tribute to a formidable scientist colleague and friend and a gift of gratitude to an inspiring leader and great in stigator. A man, who began as a theoretical physicist, made fundamental contri butions to the theory of transport processes in porous media and the mechanics of granular materials, but in his forties turned to structural geology and the me chanics of tectonic faulting - a subject that has since remained at the center of his interests and the understanding of which was substantially advanced by Georg Mandl's work. In addressing different aspects of tectonic faulting, mostly if not entirely from a theoretician's or modeler's point of view, the contribu tions to this Volume reveal some of the astonishing richness of the subject, the corresponding diversity in approaches and also challenges that lie ahead. They aptly evoke the broad scientific culture brought by Georg Mandl to the study of his favourite subject, a culture he had acquired in the course of a career in a nowadays rare environment of industrial research and which interested readers will find sketched in the Biographical Note included in this Volume. As such, as well as in their own right, the papers contributed to this Festschrift should be of interest to a wider community of Earth scientists.
Download or read book Tectonic Faults written by Mark R. Handy and published by MIT Press. This book was released on 2007 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists examine tectonic faulting on all scales--from seismic fault slip to the formation of mountain ranges--and discuss its connection to a wide range of global phenomena, including long-term climate change and evolution. Tectonic faults are sites of localized motion, both at the Earth's surface and within its dynamic interior. Faulting is directly linked to a wide range of global phenomena, including long-term climate change and the evolution of hominids, the opening and closure of oceans, and the rise and fall of mountain ranges. In Tectonic Faults, scientists from a variety of disciplines explore the connections between faulting and the processes of the Earth's atmosphere, surface, and interior. They consider faults and faulting from many different vantage points--including those of surface analysts, geochemists, material scientists, and physicists--and in all scales, from seismic fault slip to moving tectonic plates. They address basic issues, including the imaging of faults from Earth's surface to the base of the lithosphere and deeper, the structure and rheology of fault rocks, and the role of fluids and melt on the physical properties of deforming rock. They suggest strategies for understanding the interaction of faulting with topography and climate, predicting fault behavior, and interpreting the impacts on the rock record and the human environment. Using an Earth Systems approach, Tectonic Faults provides a new understanding of feedback between faulting and Earth's atmospheric, surface, and interior processes, and recommends new approaches for advancing knowledge of tectonic faults as an integral part of our dynamic planet.

This book was released on 2006-01-01 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mediterranean region and Asia provide a natural laboratory to investigate the driving forces of continental tectonics in an ongoing collisional orogen and the crustal and mantle response to various modes of deformation associated with plate boundary processes. The multidisciplinary research efforts in this region over the last fifteen years have produced a wealth of new data to better understand the interplay and feedback mechanisms between crustal and mantle processes and the dynamic landscape evolution in a complexly deforming area. A number of discrete collisional events between the Gondwana-derived continental fragments (i.e., Adria, Pelagonia, Arabia, India) and Eurasia controlled the geodynamics of the Mediterranean region and Asia during the late Mesozoic and Cenozoic. This book is a collection of research papers, presenting new data, interpretations, and syntheses on various aspects of the collision-induced tectonic, magmatic, metamorphic, and geomorphic processes that have affected the evolution of this orogenic belt. It should help us better understand the mode and nature of tectonic and magmatic processes and crustal evolution in active collision zones, and the distribution and causes of seismic and volcanic events and their impact on landscape evolution."--Publisher's website.
Download or read book Fault related Deformation Over Geologic Time written by Peter James Lovely and published by Stanford University. This book was released on 2011 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thorough understanding of the kinematic and mechanical evolution of fault-related structures is of great value, both academic (e.g. How do mountains form?) and practical (e.g. How are valuable hydrocarbons trapped in fault-related folds?). Precise knowledge of the present-day geometry is necessary to know where to drill for hydrocarbons. Understanding the evolution of a structure, including displacement fields, strain and stress history, may offer powerful insights to how and if hydrocarbons might have migrated, and the most efficient way to extract them. Small structures, including faults, fractures, pressure solution seams, and localized compaction, which may strongly influence subsurface fluid flow, may be predictable with a detailed mechanical understanding of a structure's evolution. The primary focus of this thesis is the integration of field observations, geospatial data including airborne LiDAR, and numerical modeling to investigate three dimensional deformational patterns associated with fault slip accumulated over geologic time scales. The work investigates contractional tectonics at Sheep Mountain anticline, Greybull, WY, and extensional tectonics at the Volcanic Tableland, Bishop, CA. A detailed geometric model is a necessary prerequisite for complete kinematic or mechanical analysis of any structure. High quality 3D seismic imaging data provides the means to characterize fold geometry for many subsurface industrial applications; however, such data is expensive, availability is limited, and data quality is often poor in regions of high topography where outcrop exposures are best. A new method for using high resolution topographic data, geologic field mapping and numerical interpolation is applied to model the 3D geometry of a reservoir-scale fold at Sheep Mountain anticline. The Volcanic Tableland is a classic field site for studies of fault slip scaling relationships and conceptual models for evolution of normal faults. Three dimensional elastic models are used to constrain subsurface fault geometry from detailed maps of fault scarps and topography, and to reconcile two potentially competing conceptual models for fault growth: by coalescence and by subsidiary faulting. The Tableland fault array likely initiated as a broad array of small faults, and as some have grown and coalesced, their strain shadows have inhibited the growth and initiation of nearby faults. The Volcanic Tableland also is used as a geologic example in a study of the capabilities and limitations of mechanics-based restoration, a relatively new approach to modeling in structural geology that provides distinct advantages over traditional kinematic methods, but that is significantly hampered by unphysical boundary conditions. The models do not accurately represent geological strain and stress distributions, as many have hoped. A new mechanics-based retrodeformational technique that is not subject to the same unphysical boundary conditions is suggested. However, the method, which is based on reversal of tectonic loads that may be optimized by paleostress analysis, restores only that topography which may be explained by an idealized elastic model. Elastic models are appealing for mechanical analysis of fault-related deformation because the linear nature of such models lends itself to retrodeformation and provides computationally efficient and stable numerical implementation for simulating slip distributions and associated deformation in complicated 3D fault systems. However, cumulative rock deformation is not elastic. Synthetic models are applied to investigate the implications of assuming elastic deformation and frictionless fault slip, as opposed to a more realistic elasto-plastic deformation with frictional fault slip. Results confirm that elastic models are limited in their ability to simulate geologic stress distributions, but that they may provide a reasonable, first-order approximation of strain tensor orientation and the distribution of relative strain perturbations, particularly distal from fault tips. The kinematics of elastic and elasto-plastic models diverge in the vicinity of fault tips. Results emphasize the importance of accurately and completely representing subsurface fault geometry in linear or nonlinear models.

Available in PDF, EPUB and Kindle. Book excerpt: Over 250,000 people were killed in the Tangshan, China earthquake of 1976, and other less active tectonic processes can disrupt river channels or have a grave impact on repositories of radioactive wastes. Since tectonic processes can be critical to many human activities, the Geophysics Study Committee Panel on Active Tectonics has presented an evaluation of the current state of knowledge about tectonic events, which include not only earthquakes but volcanic eruptions and similar events. This book addresses three main topics: the tectonic processes and their rates, methods of identifying and evaluating active tectonics, and the effects of active tectonics on society.
Download or read book Margins written by National Research Council and published by National Academies Press. This book was released on 1990-02-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 70 percent of the world's population is concentrated in the coastal borderlands, which geologists recognize to be the present continental margins. This new book on these continental margins provides a detailed account of a meeting which brought together specialists in marine and terrestrial geology, geochemistry, and geophysics. The workshop garnered widespread support and enthusiasm for a new direction in margins research focused on interdisciplinary studies of the fundamental processes of continental margin evolution. Scientific problems and solutions were identified for both divergent and convergent margins. Results of the workshop show that many of the fundamental plate interaction processes are common to all margins, whether formed by extension, contraction, or translation. This conclusion suggests a unified approach to margins research. A margins initiative has been proposed to follow up on the workshop results by developing science programs aimed at understanding the processes that control the initiation and evolution of continental margins.
Download or read book The Nature and Tectonic Significance of Fault Zone Weakening written by Robert E. Holdsworth and published by Geological Society of London. This book was released on 2001 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many faults appears to form persistent zones of weakness that fundamentally influence the distribution, arichitecture and movement patterns of crustal-scale deformation and associated processes in both continental and oceanic regions. They act as conduits for the focused migration of economically important fluids and also constitute one of the most important global geological hazards. This book brings together papers by an international group of Earth Scientists to discuss a broad range of topics centred upon the controls of fault weakening and the role of such faults during lithosphere deformation.
