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
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
The Hedley mining district lies within the allochthonous Quesnel Terrane of the Intermontane Belt at the eastern edge of the Upper Triassic Nicola Group. This bulletin cover the geology of this area, specifically the lithology and stratigraphy, the structural evolution, the economic geology, and the changes in geochemistry and oxidation state in the gold skarns of the region.--Includes text from document.

Book Description
Empirical Metallogeny: Depositional Environments, Lithologic Associations, and Metallic Ores, Vol. 1: Phanerozoic Environments, Associations, and Deposits focuses on the composition, characteristics, properties, and reactions of Phanerozoic metallic ore deposits. The book first offers information on depositional environments and lithologic associations and the world ocean, including ores and host associations, sea water as a metal source, and metals in marine organisms. The text then elaborates on continental margins, orogenic belts, and ophiolite association. Discussions focus on metal geochemistry and metallogeny, tectonic setting and distribution of ophiolites, trace metals and ore evolution, and supracrustal lithologic associations of orogenic belts. The publication tackles zoned mafic/ultramafic complexes in Phanerozoic orogenic belts; unimodal mafic volcanic-sedimentary association; and unimodal felsic volcanic-sedimentary association. Topics include post-depositional modification of massive sulfides, and interaction mineralization and massive tholeiitic basalt flows and arc affiliation. The book is a dependable source of information for readers wanting to study metallic ores.
