Download or read book Rare Earth Element Geochemistry written by P. Henderson and published by Elsevier. This book was released on 2013-10-22 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geochemistry, Volume 2: Rare Earth Element Geochemistry presents the remarkable developments in the chemistry and geochemistry of the rare earth elements. This book discusses the analytical techniques and the recognition that rare earth fractionation occurs naturally in different ways. Organized into 13 chapters, this volume begins with an overview of the wide array of types and sizes of the cation coordination polyhedral in rock-forming minerals. This text then examines the application of rare earth element abundances to petrogenetic problems that has centered on the evolution of igneous rocks. Other chapters consider the matching of observed rare earth element abundances with those provided by the theoretical modeling of petrogenetic processes. This book discusses as well the hypotheses on the genesis of a rock or mineral suite. The final chapter deals with the principal analytical methods. This book is a valuable resource for undergraduates, lecturers, and researchers who study petrology and geochemistry.

This book was released on 1986 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the past the application of REE geochemistry to hydrothermal ore systems has been limited. The purpose of this study is to investigate the distribution of the REE in epithermal gold deposits to determine the ability of these elements to monitor mineralization processes and to evaluate their potential as pathfinders. Epithermal gold mineralization in the North and South Moccasin Mountains, Montana, is associated with intrusive breccias and disturbed zones near contacts between Late Cretaceous-Paleocene igneous and Paleozoic sedimentary rocks. Thirty-nine samples of unmineralized and mineralized igneous and sedimentary rocks were analyzed for REE by inductively coupled argon plasma emission spectrometry. The samples were also analyzed for SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, Na2O, K20, H2O, TiO2, P2O5, MnO, CO2, Ag, Au, Ba, Cu, Pb, Rb, Sr, Tl, V, Y, Zn, and Zr. The chondrite normalized REE patterns of unaltered syenite porphyry are enriched in LREE relative to HREE and have no Eu anomaly. Samples of unmineralized altered syenite have REE patterns parallel to the unaltered patterns but are enriched in all the REE particularly the LREE. Mineralized syenite porphyry samples are all depleted in HREE, may have negative Eu anomalies, and have variable, but generally enriched, LREE abundances relative to unaltered syenite. The differences in the REE patterns of unmineralized and mineralized altered syenite porphyry are attributed to differences in alteration mineral assemblages and variations in the nature of hydrothermal fluids. The observed variations in REE abundances demonstrate that the rare earths are mobilized during alteration in epithermal systems. These preliminary results suggest that the REE are able to distinguish between unmineralized and mineralized rocks"--Document.

Book Synopsis Crust/Mantle Recycling at Convergence Zones by : Stanley R. Hart
Download or read book Crust/Mantle Recycling at Convergence Zones written by Stanley R. Hart and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of a collection of papers presented at the NATO Advanced Research Workshop (ARW) on "Crust/mantle Recycl ing at Convergence Zones," held in Antalya, Turkey, between May 25 to 29, 1987. The workshop was attended by 36 earth scientists from ten countries and 28 papers were presented. Crust/mantle recycling is one of the most fundamental processes in the Earth. The study and understanding of this process requires the consideration of the Earth as a whole system including the atmosphere, the hydrosphere and the core, as well as the crust and the mantle; effective interdisciplinary collaboration is therefore essential to our progress. The Antalya ARW gave us the opportunity to assemble key specialists from relevant branches of the earth sciences and to address our state of knowledge. This ARW proved to be very useful in attaining an interdisciplinary, mutual understanding among specialists from diverse fields such as isotope and trace element geochemistry, mineral physics, theoretical geophysics, seismology, experimental petrology, and structural geology.
Book Synopsis Formation of Gold Deposits by : Neil Phillips
Download or read book Formation of Gold Deposits written by Neil Phillips and published by Springer Nature. This book was released on 2022-06-16 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the origin of gold deposits to answer questions of science and curiosity. These answers contribute in turn to the improved exploration and mining of gold. Initially there is a summary of the methods used to address the genesis of gold deposits including some of the essential science and concepts. Five basic observations follow that apply to many gold deposits and need to be considered in any genetic ideas. Magmatic processes enriching gold are discussed followed by the role of aqueous fluids during gold deposit formation at elevated temperatures and pressures. Modifying effects after deposit formation include high-grade metamorphism, retrogression, weathering, and erosion. The main types of gold deposits are then explained within the spectrum of viable genetic ideas, with informal names for these examples that include gold-only, gold-plus, Carlin, slate-belt, epithermal, porphyry, iron oxide copper gold, and Archean greenstone. Case histories are included in which the role of gold geology contributed directly to discoveries—one example is at the province-scale and another at the goldfield-scale. Unlike other books on the subject, this one addresses virtually all gold deposit types rather than focusing on one type in isolation. The primary readership includes industry geologists, senior undergraduates, postgraduates, and those with some knowledge of science and an interest in the gold industry.

Book Synopsis Petrochronology by : Matthew J. Kohn
Download or read book Petrochronology written by Matthew J. Kohn and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-11-05 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petrochronology is a rapidly emerging branch of Earth science that links time (ages or rates) with specific rock-forming processes and their physical conditions. It is founded in petrology and geochemistry, which define a petrogenetic context or delimit a specific process, to which chronometric data are then linked. This combination informs Earth’s petrogenetic processes better than petrology or geochronology alone. This volume and the accompanying short courses address three broad categories of inquiry. Conceptual approaches chapters include petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry. Methods chapters address four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS. Mineral-specific chapters explore applications to a wide range of minerals, including zircon (metamorphic, igneous, and detrital/Hadean), baddeleyite, REE minerals (monazite, allanite, xenotime and apatite), titanite, rutile, garnet, and major igneous minerals (olivine, plagioclase and pyroxenes). These applications mainly focus on metamorphic, igneous, or tectonic processes, but additionally elucidate fundamental transdisciplinary progress in addressing mechanisms of crystal growth, the chemical consequences of mineral growth kinetics, and how chemical transport and deformation affect chemically complex mineral composites. Most chapters further recommend areas of future research.
Book Synopsis Early Earth Systems by : Hugh R. Rollinson
Download or read book Early Earth Systems written by Hugh R. Rollinson and published by John Wiley & Sons. This book was released on 2009-03-12 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early Earth Systems provides a complete history of the Earth from its beginnings to the end of the Archaean. This journey through the Earth's early history begins with the Earth's origin, then examines the evolution of the mantle, the origin of the continental crust, the origin and evolution of the Earth's atmosphere and oceans, and ends with the origin of life. Looks at the evidence for the Earth's very early differentiation into core, mantle, crust, atmosphere and oceans and how this differentiation saw extreme interactions within the Earth system. Discusses Archaean Earth processes within the framework of the Earth System Science paradigm, providing a qualitative assessment of the principal reservoirs and fluxes in the early Earth. “The book would be perfect for a graduate-level or upper level undergraduate course on the early Earth. It will also serve as a great starting point for researchers in solid-Earth geochemistry who want to know more about the Earth’s early atmosphere and biosphere, and vice versa for low temperature geochemists who want to get a modern overview of the Earth’s interior.” Geological Magazine, 2008
