Geologic setting

Geologic description

The country rocks in the area of this occurrence consist of a 2,000-meter-thick sequence of Lower Permian? and Pennsylvanian, massive volcanic flows, breccias, and subordinate volcaniclastic rocks, all largely andesitic in composition (Wilson and others, 1998). The occurrence consists of pyrite and chalcopyrite disseminated in the volcanic rocks.
