Metallogeny And Mineral Deposits Of The Nelson Rossland Map Area

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.

The 20 chapters of The Geology of Washington and Beyond�an outgrowth of a geologic symposium�present the substantial advances in recent research on the geologic history of Washington State. The 32 contributors used new conceptual developments such as sequence stratigraphy, identification and matching of terranes, and neotechtonics, as well as breakthroughs in technology such as lidar mapping, paleomagnetism, and new methods of radiometric dating, to examine the fascinating geology of Washington State and beyond. Also included is geologic mapping in areas previously known only by reconnaissance. This book will influence resource management decisions, as well as disaster and land-use planning in the region. The introductory chapters make the book accessible for undergraduate courses in geology and to the general public.
