Download or read book Geology and Platinum group element Mineralization of Alaskan type Ultramafic mafic Complexes in British Columbia written by Graham Tom Nixon and published by . This book was released on 1997 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaskan-type ultramafic-mafic complexes in British Columbia are potential hosts for commercially exploitable deposits of platinum group elements (PGEs). Such complexes are named for a distinctive suite of intrusions distributed along a narrow, northerly trending belt 600 kilometres long in south-eastern Alaska. All Alaskan-type complexes in British Columbia lie within the allochthonous terranes of the Intermontane Belt that were amalgamated and accreted to the cratonic margin of ancestral North America in the Mesozoic. This report examines the geology and PGE/noble metal geochemistry of eight specific complexes, providing information on regional geology and geochronology, structure, metamorphism, petrography, geochemistry, and mineralization. It then discusses PGE mineralization, using the Tulameen Complex and associated placers as a case study, and examines the economic potential of the complexes and their magmatic and tectonic settings.

This book was released on 2016-03-07 with total page 797 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 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

This book was released on 2019-11-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book (Special Issue) presents impressive new results related to a wide spectrum of occurrences of platinum-group minerals (PGM) and natural compounds enriched in platinum-group elements (PGE), which are associated with various complexes and deposits, such as Uralian-Alaskan-type complexes, layered intrusions and placers. The geographical locations of the involved deposits and complexes include, on a truly international scale, different areas of the Urals, Western and Eastern Sayans and Gornaya Shoria in Siberia, Southern Central Asian Orogenic Belt in China, Northern Michigan, USA, South Africa and Zimbabwe, etc. Of particular interest is the first description of a new species of PGM, thalhammerite (approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association), which is a new species of palladium-silver sulfobismuthide discovered in the Noril’sk region of Russia. Additionally, comprehensive reviews, on compositional variations in Pt–Fe alloy minerals and processes of transformations of PGM in exogenic environments, are presented which will also attract attention from international readers.

Download or read book Distribution and Behaviour of Platinum in Soils of the Tulameen Ultramafic Complex Southern British Columbia written by Stephen John Cook and published by . This book was released on 1992 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical exploration for chromitite-associated platinum deposits is hampered by a poor understanding of the distribution and behaviour of platinum in the surficial environment. This study investigates platinum content, residence sites, and mineralogy of soils developed on till and colluvium above the Tulameen Ultramafic Complex in southern British Columbia. Samples were taken of 76 soil profiles, sediments, bogs, and water above the dunite core of the Tulameen Complex. Platinum content of the -70-mesh fraction of soils and sediments was determined by fire assay-inductively coupled plasma spectrometry. Samples from 14 selected profiles were then examined in detail to determine platinum mineralogy and its distribution between different size, density, and magnetic fractions.
