Download or read book Precious Metal Enriched Skarns in British Columbia written by A. D. Ettlinger and published by Province of British Columbia, Ministry of Energy, Mines and Petroleum Resources, Geological Survey Branch. This book was released on 1989 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the well-documented 60-year history of major gold production from the world-class Nickel Plate mine in B.C., precious metal enriched (PME) skarns have only recently been recognized as a distinct class of skarn deposit. This paper is the result of studies that involved geological mapping of some selected skarn camps, extensive literature research and various laboratory studies, including whole-rock and trace element analyses, petrographic examination of sulphide and calc-silicate assemblages, and electron microprobe analyses of various garnet and pyroxene mineral phases associated with the skarn alteration. The report gives relevant data on the proven and potential PME skarns in B.C. and outlines their various characteristics, including distribution, mineralogy, geochemistry, geological controls and classification.

Book excerpt: Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.

Book excerpt: The eight articles first appeared as volume 6 (no date) of Mineral processing and extractive metallurgy review. They review new methods of recovery for gold, and to some extent, silver, focus on the particular challenges of extraction from carbonaceous ores and from various sulfide-bearing ore, and the treatment of refractory gold ore, and discuss high-temperature and biological oxidation, high- temperature chlorination, and removing metals from leach liquor.

Download or read book Basement Tectonics 8 written by Mervin J. Bartholomew and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 8th International Conference on Basement Tectonics was held in Butte, Montana, August 8-12,1988. Historically, basement tectonics conferences have focused on such topics as reactivation of faults, the influence of basement faults on metallogeny and hyrocarbon accumulation, and the use of geophysical and remote sensing techniques to interpret subsurface and surface geology. The 8th Conference diverged from past conferences in that a unifying theme was selected. Because ancient major terrane or cratonic boundaries are often postulated to be fault zones which are subsequently reactivated, the conference was organized to examine all aspects of ancient continental margins and terrane boundaries and to compare younger (Mesozoic) ones, about which more is known, with older (Paleozoic and Precambrian) ones. Moreover, because the 8th Conference was held in the northwestern United States, a greater emphasis was placed on the Mesozoic margin of western North America and the North American shield. The seven oral sessions and four poster sessions all dealt with aspects of the conference theme: characterization and comparison of ancient continental margins. The organizers extend their thanks to those individuals who graciously consented to serve as moderators for the oral sessions: John M. Bartley, Mark S. Gettings, M. Charles Gilbert, John M. Guilbert, Donald W. Hyndman, William P. Leeman, Robert Mason, and A. Krishna Sinha. The program with abstracts volume was prepared by S. E. Lewis and M. J. Bartholomew.

This book was released on 1991 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a tectonic and mineral deposit overview, then discusses deposits in North American rocks, followed by deposits formed in accreted and suspect' terrains; deposits formed at or near the sea floor or from hot springs; and those formed in successively deeper zones as magmatic deposits, vein to replacement deposits, skarns, and porphyries. Deposits within and directly linked to intrusive rocks (magmatic, porphyries, skarns), replacement deposits, possible manto deposits, deep to shallow veins and related deposits formed at the surface, volcanogenic massive sulphides and sedex deposits are then discussed. Sedimentary-hosted deposits of gypsum, barite, phosphate and other industrial minerals are not covered, nor are coal, uranium, pegmatite-hosted deposits, molybdenum prophyries or some of the less common deposit types such as carbonatites, tin greisens, and placers.
