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
The Jurassic Rossland Group in south-east British Columbia is a volcanic arc succession that contains a variety of deposits typical of volcanic arcs. This report focusses on deposits in the Group, particularly on those that have had recent exploration, and on the metallogeny of the Nelson-Rossland map area. The report first reviews the regional geology of the area and describes a number of type examples of mineral deposits in Rossland Group rocks & others in the area. These include carbonate-hosted deposits, volcanogenic massive sulphides, porphyry copper-gold deposits, skarns, and gold-quartz & polymetallic veins. The principal focus is on the deposits of the Rossland copper/gold mining camp, the second largest lode gold producing camp in the province. The regional geology around Rossland is summarized, the main deposit types are described, and a model for intrusive-related gold-sulphide veins is presented. Appendices include a table of mineral occurrences in the area, production data for the area's metallic deposits, a petrographic report, analyses of samples, reports on geochronological dating & isotope characterization, and fluid inclusion data.
