Precious Metal Enriched Skarns in British Columbia
Author: A. D. EttlingerPublisher: Province of British Columbia, Ministry of Energy, Mines and Petroleum Resources, Geological Survey Branch
ISBN:
Category : Precious metals
Languages : en
Pages : 138
Book Description
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 Description
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 Description
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.
