Comments on the geologic information

  • Geologic Description = The area of this occurrence is underlain by a 2,00-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.
  • Age = the sulfide minerals probably are syngenetic with their Lower Permian and Pennsylvanian host rocks.
