This book was released on 2008-01-08 with total page 1580 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 1965, a small group of European economic geologists gathered in Heidelberg, Germany, at the invitation of Professor G. C. Amstutz and decided to establish the Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be called Mineralium Deposita. The first issue of the journal came out in May 1966, and has now matured to a leading journal in economic geology The first Biennial SGA Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London (United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002, th the SGA Council decided that its 8 Biennial Meeting in 2005 should be held in Beijing, China, making this the first Biennial Meeting to be convened outside - th rope. Significantly, 2005 also marks the 40 anniversary of the SGA. The decision to host this year’s premier meeting in Beijing reflects the Society’s successful transition from its traditional European focus to a truly global organization, with 24% of SGA members situated in North America, 13% in Australia and Oceania, and 5% in Asia. Over the last 27 years China has made dramatic progress towards political and economic reform, and opening the nation to the outside world. China’s rapid e- nomic development demands increasing amounts of minerals, fuels and materials, and this is currently a major driver for the global economic markets.

Available in PDF, EPUB and Kindle. Book excerpt: Platinum-Nickel-Chromium Deposits: Geology, Exploration, and Reserve Base is the first reference book to combine information on the discovery of numerous minerals within existing deposits. This book recognizes the close affinity and great natural coexistence of platinum, palladium, chromium, nickel, copper, gold, and silver hosted by unique stratigraphy (mafic-ultramafic intrusive of layered ingenious complex) in a diverse structural set up. The chapters are organized in a logical sequence of introductory physical and chemical properties, demand-supply scenario, price trend, substitution-recycling and uses of these metals, stratigraphy and host rocks, geochemistry, global distribution of existing deposits in six mega continents, genetic system, reserves-resources overview, common characteristic features aiding as exploration guides for new targets, hazards, and sustainable development. This reference book is a must for students, research scholars, teachers, and professional explorers in economic geology, geography, and allied subjects. Presents over 150 full color illustrations including maps, diagrams, and charts Illustrates the key concepts in a clear and informative manner Authored by one of the world’s leading geoscientists Provides unique coverage of high value mineral deposits through an approach accessible to industry professionals, academic researchers, and students alike

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bellerophon gold deposit in the St Ives camp, Yilgarn craton, Western Australia, has been studied to assess the importance of magmatic systems in the formation of ancient gold deposits. The majority of the gold grains occur in the quartz-albite-carbonate-pyrite veins and quartz-pyrite veins. Intense albite and hematite alteration surrounds the mineralized veins, which show enrichment in Na, S, and Sr, and depletion in K, Cs, Rb, Cr, V, and Ni, compared with their unaltered equivalents. During mineralization, Bi, Te, Pb, and Mo were introduced together with Au. Multi sulfur isotopes measurements of pyrites that are genetically related to the gold mineralization from the Bellerophon, Victory, and Wallaby deposits in the Yilgarn craton, and the Beattie deposit from the Abitibi belt, Canada, show that the sulfur in the gold-bearing fluid is dominated by mass dependent fractionation (MDF), which requires the fluid to have a mantle origin or to have been derived from magma of mantle origin. Three types of fluid inclusions were identified: Type I low salinity carbon dioxide inclusions, Type II high salinity aqueous inclusions, and Type III disordered carbon bearing high salinity aqueous inclusions. Type I fluid inclusions can be further divided into Type Ia and Type Ib with high and low ratios of carbon dioxide to water, respectively. The similarity between homogenization temperatures, and the occurrence of the Type Ia and Types II inclusions within the same clusters suggest that they formed by liquid immiscibility at about 300 degree celcius. Type III fluid inclusions, which have high temperature (exceed 550 degree celcius), high salinity (38 weight percent NaCl equiv.), and a redox state that lies close to the carbon dioxide and methane buffer, are interpreted to represent the parental hydrothermal fluid. The exsolution of methane from the hydrothermal fluid, during fluid immiscibility, lead to oxidation of the remaining fluid, which in turn triggered gold precipitation. Two types of hydrothermal scheelite were identified in association with mineralization, Type I, which is enriched in the middle rare earth elements (REE), and Type II, which has a flat REE pattern. Hydrothermal apatite has a similar REE pattern to the Type I scheelite. Metamorphic apatites are distinct from the hydrothermal apatite and scheelite in geochemistry. The Sr isotopes composition of hydrothermal scheelite is similar to that of apatite from the host rocks, which indicates that the Sr isotopes in hydrothermal fluid have been modified by interaction with the wall rocks. The wide range of Sr isotopic compositions suggests that the ore-forming fluid has been transported over a long distance. The age of the Bellerophon gold deposit was determined by Ar-Ar dating muscovite extracted from ore veins. The age obtained was 2614 Ma, which is appreciably younger than the associated monzonite intrusions, which have U-Pb zircon age of 2660 Ma, and cannot be the source of the mineralization. Combining all the published ages for gold mineralization in Yilgarn craton showed that the mineralization form over an extended period from ca. 2700 Ma to ca. 2600Ma.

This book was released on 2020-05-13 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue covers a broad range of topics related to the mineralogy of noble metals (Au, Ag, Pt, Pd, Rh, and Ru) and the occurrence, formation, and distribution of these elements in natural ore-forming systems. This collection of eleven research articles discusses various problems related to these topics. I hope this Special Issue will contribute to a better understanding of the genesis of gold, silver, and other noble metal deposits as well as the behavior of these elements in endogenic and supergene environments, and suggest ways forward to solving the problem of their full extraction from ores.
