This book was released on 1974 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lamellar features in naturally deformed hornblende are identical to ( -1,01) mechanical twinning produced experimentally. Although plastic deformation features in amphiboles from tectonities are probably rare, where present, twinning may be a useful indicator of principal stress directions. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Deformation Mechanisms Rheology and Tectonics written by David J. Prior and published by Geological Society of London. This book was released on 2011 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers presents recent advances in the study of deformation mechanisms and rheology and their applications to tectonics. Many of the contributions exploit new petrofabric techniques, particularly electron backscatter diffraction, to help understand the evolution of rock microstructure and mechanical properties. Papers in the first section (lattice preferred orientations and anisotropy ) show a growing emphasis on the determination of elastic properties from petrofabrics, from which acoustic properties can be computed for comparison with in-situ seismic measurements. Such research will underpin geodynamic interpretation of large-scale active tectonics. Contributions in the second section (microstructures, mechanisms and rheology) study the relations between microstructural evolution during deformation and mechanical properties.

Book excerpt: New materials addressed for the first time include the chapters on minerals by Barber et al and the chapter on dislocations in colloidal crystals by Schall and Spaepen. Moriarty et al extend the first principles calculations of kink configurations in bcc metals to high pressures, including the use of flexible boundary conditions to model dilatational effects. Rabier et al clarify the issue of glide-shuffle slip systems in diamond cubic and related III-V compounds. Metadislocations, discussed by Feuerbacher and Heggen, represent a new type of defect in multicomponent metal compounds and alloys. - Kink mechanisms for dislocation motion at high pressure in bcc metals - Dislocation core structures identified in silicon at high stress - Metadislocations, a new type of defect, identified and described - Extension of dislocation concepts to complex minerals - First observations of dislocations in colloidal crystals

Download or read book Microtectonics written by C.W. Passchier and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microtectonics is the interpretation of small-scale deformation structures in rocks. They are studied by optical microscope and contain abundant information on the history and type of deformation and metamorphism in a rock and are therefore used by most geologists to obtain data for large-scale geological interpretations. This advanced textbook contains a large number of photographs and explanatory drawings, special chapters on related techniques, a chapter on microgauges and a simple, non-mathematical treatment of continuum mechanics with practical examples. Special terms are explained in boxes. This textbook is suited for independent use during optical studies on microstructures as a reference manual and as a manual for short courses.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of Advanced Mineralogy encompasses six different areas having two features in common: they are related to one of the largest enterprises of the second half of this century; and represent the ultimate and final extension of the concept of mineral matter. - Understanding mineral matter in Space is one of the principal purposes of cosmic exploration. This includes the results of compa rative planetology, lunar epopee, sophisticated meteorite studies (now more than 500 meteorite minerals), discovery of the interstellar mineral dust forming some 60 trillion of earth masses in the Galaxy, and terrestrial impact crater studies. It is possible now to speak of mineralogy of the Universum, and the mineralogical type of the states of matter in the Universe. Direct samples of mantle xenoliths and ultrahigh pressure-tem perature experiments make it possible to consider the mineral ogical composition of the Earth as a whole, including the upper an lower mantle and the Earth's core. Deep ocean drilling programs, a scientific fleet of hundreds of vessels and several submersibles have brought about great dis coveries in the geology, metalogeny, and mineralogy of the ocean floor the largest part of the Earth's surface, in particular revealing new genetic, crystallochemical, and ore types of min eral formation.

Download or read book Deformation Mechanisms Rheology and Tectonics written by D. Gapais and published by Geological Society of London. This book was released on 2005 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of 18 papers on deformation mechanisms, rheology and tectonics. The main approaches include experimental rock deformation, microstructural analysis, field structural studies, analogue and numerical modelling. New results on various topics are presented, ranging from brittle to ductile deformation and grain-scale to lithospherescale mechanisms. The volume contains review papers on several major current topics, such as the rheology of the lithospheric mantle and the mechanisms of exhumation of high-pressure tectonic units, as well as research papers on kinematic and mechanical analysis of rock deformation and related new techniques. Several contributions emphasize the increasing ability and wish of researchers to strengthen the links between small-scale physical mechanisms and large-scale tectonics. The volume will be of interest to academic and industrial researchers in the fields of structural geology, interactions between metamorphism, fluids and deformation, and large-scale tectonic processes.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of Deformation and Fracture contains the proceedings of the Interdisciplinary Conference on the Mechanisms of Deformation and Fracture held at the University of Luleå in Sweden on September 20-22, 1978. The papers explore the mechanisms underlying deformation and fracture of materials such as pearlite, metals, quartz, soils, and rocks. Results of theoretical and experimental studies on topics ranging from electromagnetic detection of low-cycle fatigue to stress and strain distribution in two-phase systems are presented. This book is comprised of 37 chapters and begins with a discussion on the interrelationships among solid mechanics, earth sciences, and material sciences. Subsequent chapters focus on the low-cycle behavior of case hardened steel; deformation and shear of normally consolidated flocculated kaolin; analytical modeling in inelasticity; creep mechanisms in clay; and initiation of crack growth at full plasticity. Plastic flow mechanisms and the rheological properties of the Earth's mantle are also examined, along with the fracture of glassy thermoplastics. The final chapter presents a thermodynamic model of consolidation in cohesive soils. This monograph will be a valuable resource for students and practitioners of mechanical engineering, metallurgy, materials science, and earth sciences.
