Geologic setting

Geologic description

This occurrence consists of disseminated pyrite in fine-grained schist, adjacent to a Tertiary granitic intrusion (Kurtak and others, 1992). A sample of the schist contains 200 parts per million copper and 100 parts per million zinc (Miller and others, 1978). Four U.S. Bureau of Mines samples contain up to 56 parts per million copper (Kurtak and others, 1992).
