Current Topics in Structural Geology is a collection of invited papers on particular topics of interest in structural geology, from field-based problems on the scale of terranes to microstructures in nature and experiment. Contributors also explore earthquake faulting; S-C mylonites; tectonics and hydrogeology of accretionary prisms; deformation mechanisms; transparent polycrystals; shape and lattice preferred orientations; and mushroom-shaped diapirs. This text is comprised of 13 chapters; the first of which introduces the reader to shallow crustal earthquakes and the structural geology of fault zones. The first chapter also emphasizes the seismogenic regime, strike-slip earthquake rupture processes, structural questions posed by seismology, and mesothermal gold-quartz lodes hosted in steeply inclined shear zones of mixed 'brittle-ductile' character. Discussion then turns to normal faulting in the upper continental crust, along with the application of a method based primarily on fault slip data analysis to determine paleostress in terms of orientation and magnitude. The mechanical behavior and deformation textures of simulated halite shear zones are considered, with special regard to the internal structures of S-C mylonites and their mechanical implications. The remaining chapters examine the role of decollement zone in the tectonics and hydrogeology of accretionary prisms; synkinematic microscopy of transparent polycrystals; and the origin of metamorphic core complexes and detachment faults formed during Tertiary continental extension in the northern Colorado River region. This book is intended primarily for students and practitioners of structural geology.

This state-of-the-art text offers students balanced coverage of the full range of topics, supported by a wealth of outstanding illustrations and photographs. The text opens with an overview of basic geologic principles that paves the way for a better understanding of structural geology. The topics of stress and strain, deformation mechanisms, and strain measurement provide a foundation upon which the text's remaining coverage is built. Self-contained chapters meet instructor's individual needs. A brief introduction to geophysical techniques, principally seismic reflection and refraction, Earth magnetism, and gravity, enhances a better understanding of crustal structures. This latest edition has been revised for greater clarity and to incorporate the most current technical information possible. *Provides balanced coverage of all topics, supported by numerous illustrations and photographs. *An introductory review of fundamental geologic principles and laws, geochronology, and principles of equilibrium gives students a strong foundation and prepares them for subsequent topics. *Essays in each chapter encourage further study in key subjects. Each chapter offers a short section on an ad

In the case of nearly all branches of science a great advance was made when accurate quantitative methods were used of more qualitative. One great advantage of this is that it necessitates more accurate thought, points out what remains to be learned, and sometimes small residual quantities, which otherwise would escape attention, indicate important facts.

The practical application of structural geology in industry is varied and diverse; it is relevant at all scales, from plate-wide screening of new exploration areas down to fluid-flow behaviour along individual fractures. From an industry perspective, good structural practice is essential since it feeds into the quantification and recovery of reserves and ultimately underpins commercial investment choices. Many of the fundamental structural principles and techniques used by industry can be traced back to the academic community, and this volume aims to provide insights into how structural theory translates into industry practice. Papers in this publication describe case studies and workflows that demonstrate applied structural geology, covering a spread of topics including trap definition, fault seal, fold-and-thrust belts, fractured reservoirs, fluid flow and geomechanics. Against a background of evolving ideas, new data types and advancing computational tools, the volume highlights the need for structural geologists to constantly re-evaluate the role they play in solving industrial challenges.

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.

The extensively revised third edition offers a rich, full-color art program, unmatchedin helping students visualize complex geologic phenomena in three dimensions.

This collection of research and review papers addresses the question of structural evolution during deformation to high strains and the physical properties of rocks that have been affected by high-strain zones. The discussions range from natural examples at outcrop to microscopic studies. They include experiments and numerical models based on the active processes in high-strain zones as well as studies on the physical properties of highly strained rocks in the field and laboratory. Specific questions addressed include magnetotelluric imaging of faults, magnetic fabrics, fabric development, seismic properties of highly strained rocks, change of rheology with strain, influence of melt on the localization of deformation, the relationship between deformation and metamorphism as well as new methods in the analysis of deformation. The book is aimed at an interdisciplinary group of readers interested in the effects of high strain in rocks.
