Geologic setting

Geologic description

This occurrence is based on mining claims located for copper (U.S. Bureau of Mines, 1973; MacKevett and Holloway, 1977). The area of claims is probably underlain by Jurassic quartz diorite (Detterman and Reed, 1980). The occurrence probably consists of small concentrations of copper minerals such as chalcopyrite or the oxidized copper carbonate, malachite.
