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.

The Cowichan Lake area lies at the southeastern end of the Vancouver Island Ranges and is characterized by fairly rugged topography accentuated by glaciation. The area is divided into two regions of differing structural style by a major thrust fault running along Cowichan Lake. This report introduces the geological setting of the areas and describes its lithology and stratigraphy, structure and tectonics from the Late Devonian to the Eocene, and the metamorphism and alteration of the area's sedimentary and igneous formations. The final section of the report reviews the history of mineral exploration in the area, outlines the regional metallogeny, and classifies the mineral deposits found in the area. The appendices include tabulated data, descriptions of mineral occurrences and fossils, and a summary of assessment report work recorded within the area.

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.

The Alberni-Nanaimo Lakes area lies at the southeastern end of the Vancouver Island Ranges and is characterized by fairly rugged topography accentuated by glaciation. The area covers one of a series of major geanticlinal structures constituting the structural fabric of the Wrangellia terrane of Vancouver Island. This report introduces the geological setting of the Alberni-Nanaimo Lakes area and describes its lithology and stratigraphy, geologic structure and tectonics from the Late Devonian to the Eocene, and metamorphism and alteration in the area's sedimentary and igneous formations. The final chapter reviews the history of mineral exploration in the area, outlines the regional metallogeny, and classifies the types of mineral deposit present in the area. The appendices contain tabulated data, descriptions of mineral occurrences and fossils, and a summary of assessment report work recorded within the area.

Vancouver Island's peaceful, bucolic nature betrays little of its violent natural history, but in Geology of Southern Vancouver Island fascinating events in the turbulent geological history and architecture of the Island are revealed.
