Download or read book Structural Control of Mineral Deposits written by Alain Chauvet and published by MDPI. This book was released on 2019-04-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Geodynamics of the Alps consists of three volumes. This first volume describes the recent and present-day structure and tectonic setting of the Alpine chain, from the lithospheric mantle to brittle crust and surface topography. It also provides a historical overview of Alpine research, with two chapters covering specific Alpine regions (Corsica and the Eastern Alps) through all phases of Alpine history. The aim of this book is to create a space for experts on Alpine research to present the state of the art of specific subjects and provide their own interpretations.
Download or read book Tectono metamorphic evolution of the continental units along the edge between Alpine and Hercynian Corsica written by Maria Di Rosa and published by Firenze University Press. This book was released on 2022 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work the central area of Corsica island was studied in order to reconstruct the tectono-metamorphic history of the continental and oceanic high pressure units that occupy the structurally deeper levels of the tectonic stacking of Alpine Corsica and their stratigraphic and structural relationship with the European margin (Hercynian Corsica). The study includes the geological mapping, the mesoscale and microscale structural analysis, the acquisition of chemical analyzes and micromaps with the microprobe, thermobarometric estimation through specific methodologies for metapelites, U-Th-Pb dating of zircons and allanites. The results obtained allows to reconstruct the geodynamic model of this sector of the Alpine belt from the Permian to the Burdigalian.

Download or read book Advances in Interpretation of Geological Processes written by Maria Iole Spalla and published by Geological Society of London. This book was released on 2010 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iterative comparison of analytical results and natural observations with predictions of numerical models improves interpretation of geological processes. Further refinements derive from wide-angle comparison of results from various scales of study. In this volume, advances from field, laboratory and modelling approaches to tectonic evolution - from the lithosphere to the rock scale - are compared. Constructive use is made of apparently discrepant or non-consistent results from analytical or methodological approaches in processing field or laboratory data, P-T estimates, absolute or relative age determinations of tectonic events, tectonic unit size in crustal-scale deformation, grain-scale deformation processes, various modelling approaches, and numerical techniques. Advances in geodynamic modelling critically depend on new insights into grain- and subgrain-scale deformation processes. Conversely, quantitative models help to identify which rheological laws and pa-rameters exert the strongest control on multi-scale deformation up to lithosphere and upper mantle scale

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 A Practical Guide to Rock Microstructure written by Ron H. Vernon and published by Cambridge University Press. This book was released on 2018-12-06 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clear understanding of the processes responsible for observed rock microstructures is essential for making reliable petrogenetic interpretations, including inferences made from chemical and isotopic analyses of minerals. This volume presents a comprehensive survey of rock microstructures, emphasising basic concepts and the latest methods, while highlighting potential pitfalls in the interpretation of the origin of rock microstructure. Richly illustrated with over 250 colour photographs, including more than 10 percent new photomicrographs and several mesoscopic images, it demonstrates the basic processes responsible for the wide variety of microstructures in igneous, metamorphic and sedimentary rocks. This second edition includes extensive updates to the coverage of igneous rocks as well as recent ideas on physical processes in migmatites and partial melting of sedimentary rocks. This practical guide will continue to be an invaluable resource to advanced students and early-career researchers of mineralogy, petrology and structural geology, as well as professional geologists and material scientists.
Download or read book Deformation Mechanisms Rheology and Tectonics written by Siese de Meer and published by Geological Society of London. This book was released on 2002 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes.
Download or read book Current Topics in Structural Geology written by P. L. Hancock and published by Elsevier. This book was released on 2013-08-29 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Flow Processes in Faults and Shear Zones written by G. Ian Alsop and published by Geological Society of London. This book was released on 2004 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faults and their deeper level equivalents, shear zones, are localized regions of intense deformation within the Earth. They are recognized at all scales from micro to plate boundary, and are important examples of the nature of heterogeneous deformation in natural rocks. Faults and shear zones are significant as they profoundly influence the location, architecture and evolution of a broad range of geological phenomenao The topography and bathymetry of the Earth's surface is marked by mountain belts and sedimentary basins that are controlled by faults and shear zoneso In addition, faults and shear zones control fluid migration and transport including hydrothermal and hydrocarbon systems. Once faults and shear zones are established, they are often long-lived features prone to multiple reactivation over very large time-scales. This collection of papers addresses lithospheric deformation and the rheology of shear zones, together with processes of partitioning and the unravelling of fault and shear zone histories.
