This book was released on 2016-03-07 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly Siderophile and Strongly Chalcophile Elements in High Temperature Geochemistry and Cosmochemistry, Volume 81 This RiMG (Reviews in Mineralogy & Geochemistry) volume investigates the application of highly siderophile (HSE) and strongly chalcophile elements. This volume has its origin in a short course sponsored by the Mineralogical Society of America and the Geochemical Society held in San Diego, California on the 11th and 12th December 2015, ahead of the American Geophysical Union’s Fall Meeting, which featured a session with the same title. Topics in this volume include: analytical methods and data quality experimental constraints applied to understanding HSE partitioning nucleosynthetic variations of siderophile and chalcophile elements HSE in the Earth, Moon, Mars and asteroidal bodies HSE and chalcophile elements in both cratonic and non-cratonic mantle, encompassing both sub-continental and sub-oceanic lithosphere the importance of the HSE for studying volcanic and magmatic processes, and an appraisal of the importance of magmatic HSE ore formation in Earth’s crust. Highly siderophile and strongly chalcophile elements comprise Re, Os, Ir, Ru, Pt, Rh, Pd, Au, Te, Se and S and are defined by their strong partitioning into the metallic phase, but will also strongly partition into sulfide phases, in the absence of metal. The chemical properties of the HSE mean that they are excellent tracers of key processes in high temperature geochemistry and cosmochemistry, having applications in virtually all areas of earth science. A key aspect of the HSE is that three long-lived, geologically useful decay systems exist with the HSE as parent (107Pd-107Ag), or parent-daughter isotopes (187Re-187Os and 190Pt-186Os). The material in this book is accessible for graduate students, researchers, and professionals with interests in the geochemistry and cosmochemistry of these elements, geochronology, magmatic ore bodies and the petrogenesis of platinum-group minerals.

Download or read book Serpentine Geoecology of Western North America written by Earl B. Alexander and published by Oxford University Press. This book was released on 2006-11-02 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geoecology is a fruitful interdisciplinary field, relating rocks to soils to plant and animal communities and studying the interactions between them. Modern geoecology especially concentrates on showing how geology and soils affect the structure, composition, and distribution of plant communities in a certain research area. This book applies the principles of geoecology to Western North America, and to a specific kind of rock, the fascinating serpentine belts that run along the continental margins of the West Coast from Alaska to Baja. The authors come from different disciplines: Alexander is a soil scientist, Coleman a geologist, Harrison a biological researcher, and Keeler-Wolfe a vegetation ecologist. It begins with an overview of the geology of this rock and this region, covering mineralogy, petrology, and stratigraphy of West Coast serpentine. It will continue with serpentine soils and their development and distribution, and serpentine effects on plants and vegetation and animals. The serpentine geoecology of the different regions of Western North America, concentrating on California, will conclude the study. So, this academic book should appeal to plant ecologists, soil scientists, researchers in geoecology, and students in advanced courses in soil science.

Download or read book Processes and Ore Deposits of Ultramafic Mafic Magmas through Space and Time written by Sisir K. Mondal and published by Elsevier. This book was released on 2017-09-08 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes and Ore Deposits of Ultramafic-Mafic Magmas through Space and Time focuses on the fundamental processes that control the formation of ore deposits from ultramafic-mafic magmas, covering chromite, platinum-group element (PGE), Ni-sulfides and Ti-V-bearing magnetite. The exploration, exploitation and use of these magmatic ores are important aspects of geology and directly linked to the global economy. Magmatic ores form from ultramafic-mafic magmas and crystallize at high-temperature after emplacement into crustal magma chambers, and are genetically linked to the evolution of the parental magmas through space and time. This book features recent developments in the field of magmatic ore deposits, and is an essential resource for both industry professionals and those in academia. - Elucidates the relationships between tectonic settings and magmatic ore mineralization - Provides the links between magma generation in the mantle and ore mineralization at crustal levels - Features the latest research on changing patterns in magmatic ore mineralization through time and their bearing on the chemical evolution of the Earth's mantle

Download or read book Crustal Cross Sections from the Western North American Cordillera and Elsewhere written by Robert Bruce Miller and published by Geological Society of America. This book was released on 2009 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Exposed crustal cross sections provide a unique direct view of continental crust, and are a major source of insights into variations in lithologic and geochemical composition, structural style, metamorphism, plutonism, and rheology with progressive depth through the crust. This volume provides a synthesis of crustal cross sections with a special emphasis on Phanerozoic sections from the western North American Cordillera, supplemented by articles on lower- and mid-crustal sections through Proterozoic crust in North America and Australia, and the classic crustal section of Fiordland, New Zealand. Many of the papers describe multidisciplinary research on crustal sections and include data from various combinations of structural analysis, geochemistry, geothermobarometry, geochronology, geophysics, and other disciplines. The volume also discusses common problems for the interpretation of crustal cross sections, including how sections that expose deep-crustal rocks are eventually exhumed, and leading to the conclusion that there is no simple 'standard model' for continental crust. This volume will be useful to those interested in structural geology, tectonics, geodynamics, regional geology, petrology, geochemistry/isotope geology, and geophysics."--Pub. desc.
