Origin and Tectonic Setting of Ophiolitic Ultramafic and Related Rocks in the Atlin Area, British Columbia (NTS 104N) by Christopher Henry Ash (H.),British Columbia. Geological Survey Branch Pdf

This paper presents the results of a detailed investigation of the tectonic setting and origin of ultramafic and related rocks in the Atlin area. The Atlin area was selected for detailed study because of its excellent road access, the large number of listwanite-related lode gold occurrences, and the extensive exploration database available for many of these occurrences. Following detailed mapping of the ultramafic rocks underlying the town of Atlin and Monarch Mountain in 1989, the area was revisited in 1990 and the map area extended to establish tectonic relationships between the ultramafic and surrounding lithologies. The phase chemistry of the harzburgite and associated dunite were investigated and are used to establish the origin of the units. Whole-rock major, trace, and rare-earth element chemistry is presented for basaltic rocks spatially associated with the ultramafics. These data are used to place constraints on the paleotectonic eruptive setting of the unit and to model the character of the mantle source from which the rocks were derived.

Skarns in British Columbia by Gerald E. Ray,I. C. L. Webster,British Columbia. Ministry of Employment and Investment,British Columbia. Geological Survey Branch Pdf

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.

Tectonics, Metallogeny, and Discovery by Maurice Colpron,Thomas Bissig,Rusk Brian G.,John F. H. Thompson Pdf

This summary report commences with a brief metallogenic overview of the northern Pacific Rim, with particular attention paid to the world-class Mesozoic and Cenozoic ore deposits that define the region's premier metallogenic provinces. This is followed by a summary of the relative attractiveness of the region's various mining jurisdictions, as recorded by recent exploration activity.

Distribution, Nature, and Origins of the 2400 BP Eruption Products of Mount Meager, British Columbia by M. V. Stasiuk,James K. Russell,C. J. Hickson Pdf

The Bridge River volcanic assemblage comprises the eruptive products of an eruption of Mount Meager, British Columbia, that occurred 2,400 years ago. The products include airfall pumice, pyroclastic flows, lahars, and lava flow. This report describes new units of the assemblage that were previously unrecognised, new stratigraphic relationships, and new origins for some of the deposits. It also details the petrographic characteristics of Plinth Assemblage volcanic rocks found underlying and overlying Bridge River deposits. Chemical compositions of representative rocks from the assemblages are presented. Finally, the report discusses the eruption trigger, progression of eruptive activity, and the transition from explosive to effusive behaviour during the eruption.

Geological Setting of the Rossland Mining Camp by British Columbia. Ministry of Energy, Mines and Petroleum Resources,James T. Fyles Pdf

This report summarizes geological work near the city of Rosslandin the West Kootenay district of southeastern British Columbiacarried out more than 10 years ago. The purpose of the work wasto clarify the geological setting of the molybdenum deposits onRed Mountain west of the city, which at that time were beingmined. The work led to a new geological map of the Rossland campand to the recognition of some new geological relationships.
