Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 56. "The roses seem to have a mildew," Lucy said as I drank my morning coffee. "I'll ask Hugh about it," flashed through my mind, but not past my lips since he's been dead for over two years. I wonder if this isn't typical for his friends and colleagues. Hugh's ability and willingness to help, his unselfish cooperation not just in research but in life, are what made him special to those who worked closely with him. Many who read this volume are familiar with the varied contributions he made to rock mechanics and to high?]pressure research. Consistent with his reputation, the things that impressed me when I first worked with Hugh in 1969 were his enthusiasm for work and his ability to keep pressure systems working well. Although these qualities still come to mind when I think of Hugh, the thing that usually remains is a warm feeling of pleasure at having been his friend and shared part of his life.

Book Description
This monograph deals with the part of the field of ex-' perimental rock deformation that is dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction has been drawn between the fields of brittle und ductile behaviour in rock, corresponding more or less to a distinction between the phenomena of fracture and flow. It is hoped eventually to present a survey of the ductile field in a separate volume. The last chapter of this volume deals with the transition between the two fields. The scope of this survey has been limited to the mec.hanical properties of rock viewed as a material on the laboratory scale. Thus, the topic and approach is of a "materials science" kind rather than of a "structures" kind. We are dealing with only one part of the wider field of rock mechanics, which also includes structural or boundary value problems, for example, those of the stability of slopes, the collapse of mine openings, earth quakes, the folding of stratified rock, and the convec tive motion of the earth's mantle. One topic thus ex cluded is the role of jointing, which it is commonly necessary to take into account in applications in engi neering and mining, and probably often in geology too.

Book Description
Finding viable solutions to many of the problems threatening our environment hinges on understanding the rocks below the earth's surface. For those evaluating the relative hazards of radioactive waste sites, investigating energy resources such as oil, gas, and hydrothermal energy, studying the behavior of natural hazards like earthquakes and volcanoes, or charting the flow of groundwater through the earth, this book will be indispensable. Until now, there has been no book that treats the subject of the nature and behavior of rocks in a comprehensive yet accessible manner. Yves Gu guen and Victor Palciauskas first discuss the physical properties of rocks, proceeding by chapter through mechanical, fluid flow, acoustical, electrical, dielectric, thermal, and magnetic properties. Then they provide the theoretical framework for achieving reliable data and making reasonable inferences about the aggregate system within the earth. Introduction to the Physics of Rocks covers the important and most current theoretical approaches to the physics of inhomogeneous media, including theoretical bounds on properties, various effective medium theories, percolation, and fractals. This book will be of use to students and researchers in civil, petroleum, and environmental engineering and to geologists, geophysicists, hydrologists, and other earth scientists interested in the physics of the earth. Its clear presentation, with problems at the end of each chapter and selective references, will make it ideal for advanced undergraduate-or graduate-level courses.

Book Description
This book is a comprehensive treatment of the elastic volumetric response of sandstones to variations in stress. The theory and data presented apply to the deformations that occur, for example, due to withdrawal of fluid from a reservoir, or due to the redistribution of stresses caused by the drilling of a borehole. Although the emphasis is on reservoir-type sandstones, results and methods discussed are also applicable to other porous rocks.Part One concerns the effect of stress on deformation and discusses porous rock compressibility coefficients. Elasticity theory is used to derive relationships between the porous rock compressibility coefficients, the porosity, and the mineral grain compressibility. Theoretical bounds on the compressibility coefficients are derived. The concept of effective stress coefficients is examined, as is the integrated form of the stress-strain relationships. Undrained compression and induced pore pressures are treated within the same general framework. Part One is concluded with a brief, elementary introduction to Biot's theory of poroelasticity. All the results in Part One are illustrated and verified with extensive references to published compressibility data.Part Two deals with the relationship between pore structure and compressibility, and presents methods that permit quantitative prediction of the compressibility coefficients. Two- and three-dimensional models of tubular pores, spheroidal pores, and crack-like "grain boundary" voids are analyzed. A critical review is made of various methods that have been proposed to relate the effective elastic moduli (bulk and shear) of a porous material to its pore structure. Methods for extracting pore aspect ratio distributions from stress-strain data or from acoustic measurements are presented, along with applications to actual sandstone data.Part Three is a brief summary of experimental techniques that are used to measure porous rock compressibilities in the laboratory.The information contained in this volume is of interest to petroleum engineers, specifically those involved with reservoir modeling, petroleum geologists, geotechnical engineers, hydrologists and geophysicists.

Book Description
This book originates in the French classic "Principes de Tectonique" (Masson, 1983), written by professor Adolphe Nicolas, and the more recent "Principes de Tectonique" by J.L. Bouchez and A. Nicolas (De Boeck, 2018). This English edition is an up-to-date and augmented version that keeps the concise and rigorous writing of its inspiring predecessors. It is largely based on laboratory and field experience of both authors, with a focus towards hard rocks and magmatic rocks from both the continental crust worldwide and the mantle, principally from the Oman ophiolites. The book includes more than 250 illustrations, most of them original. In addition to classic geological subjects, the book includes elements such as plastic deformation of ice, quartz and olivine, fabric acquisition in rocks and magmas, measurement and orientation of stress, together with basic background information on neotectonics, geophysics and other practical tools such as magnetic fabrics not commonly treated in geological books. Since the targeted readers are present day young students, a few exercises of structural geology are included to improve their abilities. This book aims principally at students of Geology, at both the undergraduate and graduate levels. However, due to its numerous illustrations and rather concise writing, anyone interested in rock deformation and/or tectonics will find key answers in this book.
