Early Jurassic Rossland Group, Southern British Columbia by Trygve Höy,Kathryn P. E. Dunne,British Columbia. Geological Survey Branch,British Columbia. Ministry of Employment and Investment Pdf
The Rossland Group in south-eastern British Columbia comprises intermediate to mafic volcanic rocks and associated clastic rocks of Lower Jurassic age. The Group hosts a variety of gold and silver deposits and continues to be a target of mineral exploration. The purpose of the study reported is to develop a better understanding of the nature, timing, and controls of mineralization in the Group, particularly the intrusion-related gold-copper veins in the Rossland camp. The report describes the Rossland Group stratigraphy, its paleotectonic setting, and associated intrusions. It summarizes the structure of the Rossland Group area and presents a tectonic model for the Group. Information is also included on the regional geologic setting and the geochemistry of the Elise Formation and plutonic rocks.
