The elucidation of the mechanisms and kinematics of shear zone deformation, at both local and regional scales, is the subject of a great deal of interest to scientists in the hydrocarbon industry, in seismology, and in structural geology more generally. This book comprises a collection of five theoretical and twelve regional contributions to the subject from a number of leading researchers in the field, with particular emphasis on work carried out in the Indian subcontinent. The book will be invaluable to advances students and researchers involved in the kinematics of shear.

Proterozoic Orogens of India: A Critical Window to Gondwana provides a unique opportunity to understand a cross-section of the well-exposed and best-studied part of Earth's crust and the processes of continental collision.

Study of structures associated with shear zones is a crucial aspect to understand the deformation mechanism associated with such zones. Shear zones have been emphasized since it will lead to many latest applied studies such as radioactive waste disposal, groundwater flow etc. For the sake of brevity, research papers cannot show all possible variation in structures found in shear zones. The proposed book aims to present some of these structures in great details with attractive colour photographs. Each photograph will have a comprehensive caption.

This review of shear-sense indicators in natural geological deformation structures provides an overview of geological flow and detailed explanations on the use of foliations, stiff inclusions, folds, and veins as indicators of shear-sense. The review's aim is to examine types of flow, and the kinematically significant structures which form in them, from a perspective which should be accessible to all interested geologists.

Our understanding of earthquakes and faulting processes has developed significantly since publication of the successful first edition of this book in 1990. This revised edition, first published in 2002, was therefore thoroughly up-dated whilst maintaining and developing the two major themes of the first edition. The first of these themes is the connection between fault and earthquake mechanics, including fault scaling laws, the nature of fault populations, and how these result from the processes of fault growth and interaction. The second major theme is the central role of the rate-state friction laws in earthquake mechanics, which provide a unifying framework within which a wide range of faulting phenomena can be interpreted. With the inclusion of two chapters explaining brittle fracture and rock friction from first principles, this book is written at a level which will appeal to graduate students and research scientists in the fields of seismology, physics, geology, geodesy and rock mechanics.

Atlas of Deformed and Metamorphosed Rocks from Proterozoic Orogens is a richly illustrated reference book featuring over 660 full-color field images of a range of lithologies from some Proterozoic terrains that were subjected to multiple events of magmatism, deformation, metamorphism, and metasomatism. The Atlas focuses on amphibolite to granulite facies lithologies and associated ma?c-ultrama?c rocks from Proterozoic orogens of India, Sri Lanka, Botswana, South Africa, East Antarctica, and Western Australia. Each chapter in the book begins with a brief review of geology, including deformation and metamorphic history, along with a regional geological map to help readers to visualize the ?eld observations in the relevant geological context. Each image is accompanied by a concise description providing location, lithology, structural fabric, possible deformational history, metamorphic features, partial melting, metasomatism, and other important crustal processes. This Atlas is an important source of information for a broad range of earth scientists, graduate and undergraduate students, researchers, academicians, and other professionals. This book will form a great treasure to those geoscientists who never had an opportunity to visit any of the Proterozoic orogenic belts. - Features over 660 full-color photographs representing typical lithologies and associated structural, metamorphic features, and other crustal processes from different Proterozoic orogens - Highlights the significance of field photographs in advancing new knowledge which may provide pathways for new research - Covers many important Proterozoic terranes of East Gondwana - Presents regional geologic maps from each Proterozoic orogen

Folding and Fracturing of Rocks was first published in 1967. It was one of the first major publications aimed at developing for geologists the basic theory of stress and strain in mathematical terms and explaining how this theory could be used to solve practical problems in structural geology and tectonics. Although out-of-print for many years, it is still one of the most frequently cited and quoted texts in modern research publications in structural geology. Although texts discussing the basic theory of stress and strain had been long available in engineering, metallurgic and materials science, very few of these texts made any reference to the application of these principles to the study of rock strain, fracturing and folding processes commonly arising in geology. Folding and Fracturing of Rocks developed the theory of both small and large finite strain with particular emphasis on progressive deformation and its geological implications for the development of the structures actually observed in naturally deformed rocks. It was one of the first textbooks to discuss the practical methods for evaluating the states of finite strain in two and three dimensions and the implications of these methods to further our understanding of structural geometry. The book set out the concepts of displacement and finite strain and showed how strain states could be represented in diagrammatic forms as originally devised by Otto Mohr for states of stress. Many of the developments were novel at the time of publication and have had major applications in subsequent research. The discussions and methods of strain analysis set out in Folding and Fracturing of Ricks have stood the test of time and many of the subsequent research developments in structural geology have their origins in this book. The reasons for the relevance of this book to current research are first, the book is based on sound mathematical principles that have not become dated and second, the discussions of deformation theory are illustrated with many photographs of the structures seen in naturally deformed rocks. The author has always been of the opinion that the structures actually observed in naturally formed rocks form the key to our understanding of tectonic processes and that the development of mechanical models for the origin of these structures must always be compared with natural systems if they are to be truly relevant. John Ramsay was born in London in 1931. He did his doctoral research in the Scottish Highlands working on the deformation patterns seen in complexly folded rocks of the Moine Series and the relationships seen in folded basement and cover rocks obtaining his Ph.D. in 1954. After undertaking his military service in the Corps of the Royal Engineers (as Violoncellist and Tenor drummer) he was appointed to the teaching staff of Imperial College in 1957. Subsequently he held Professorships at London University and Leeds University. In 1977, he was appointed to a Professorship of Geology at the Eidgen ssische Technische Hochschule and University of Z rich, Switzerland. John Ramsay has been author and co-author of four books and many papers in structural geology. His work in advancing structural geology has been recognized by the awards of the Bigsby and Wollaston medals of the Geological Society, the Prestwich Medal of the Soci t G ologique de France, the Holmes Medal of the European Union of Geosciences, the Tranenster Medal of the University of Li ge, and in 1992 he was appointed to the Order of Commander of the British Empire in the Queen's Honours list.

Lavishly illustrated in color, this textbook takes an applied approach to introduce undergraduate students to the basic principles of structural geology. The book provides unique links to industry applications in the upper crust, including petroleum and groundwater geology, which highlight the importance of structural geology in exploration and exploitation of petroleum and water resources. Topics range from faults and fractures forming near the surface to shear zones and folds of the deep crust. Students are engaged through examples and parallels drawn from practical everyday situations, enabling them to connect theory with practice. Containing numerous end-of-chapter problems, e-learning modules, and with stunning field photos and illustrations, this book provides the ultimate learning experience for all students of structural geology.
