Cambrian to Mississippian metasedimentary and metavolcanic rocks of the Eagle Bay Assemblage in the Adams Lake area of south central interior British Columbia host numerous polymetallic sulphide deposits. This paper describes the Samatosum and Rea massive sulphide deposits located in that area, their geological settings, structure, metamorphism, and mineralization. Some fundamental structural & stratigraphic problems in the region are addressed, and implications for understanding the genesis of the sulphide mineralization are discussed.
Describes how metamorphic rocks are formed, where they are found, and their uses.
This report outlines preliminary field results of bedrock mapping of a central Baffin Island study area that straddles the eastern segment of the Trans-Hudson Orogen.
The Aylmer Lake volcanic belt, located north of the north-east end of Great Slave Lake, defines an upward-facing structural dome intruded in its core by a number of granitoid plutons and overlain by multiply folded metaturbidite units.
