Geologic descriptionThe rocks in the vicinity are deformed and metamorphosed Silurian or Devonian carbonate, clastic and volcanic clastic rocks that have been intruded by Upper Jurassic and Lower Cretaceous granitic and dioritic rocks (Brew and others, 1992). This occurrence is in a geologically complex area characterized by a variety of metamorphic rocks, small granitic plutons, and mafic dikes (MacKevett and others, 1971). The occurrence is associated with volcanic rocks and consists of pyrite and chalcopyrite in a cellular siliceous matrix (Cobb, 1978 [OFR 78-374]). | |
