Geologic setting

Geologic description

The country rock at this occurrence is probably mainly Jurassic quartz diorite (Detterman and Reed, 1980). The quartz diorite has local phases of diorite and granodiorite and contains roof pendants of gneiss and of mafic and ultramafic rocks. The occurrence is based on claims located for copper, probably as chalcopyrite (U.S. Bureau of Mines, 1973; MacKevett and Holloway, 1977). No further data are available.
