Geologic setting

Geologic description

This occurrence consists of disseminated pyrite in altered, contact-metamorphosed argillite and graywacke, adjacent to a Tertiary granitic intrusion (Csejtey and Miller, 1978). A sample of graywacke contains 500 parts per million copper, 100 parts per million nickel, and 300 parts per million chromium (Miller and others, 1978).
