Geologic setting

Geologic description

A 2- to 3-foot-thick quartz vein is exposed on a cliff on the bank of a stream. The vein appears to crosscut the foliation of the graphitic schist host rock (Kimble and others, 1984). A representative sample of the vein contained 15 ppm silver, 0.15 ppm gold, 1,300 ppm lead, and 250 ppm zinc. The host rocks are part of the Cretaceous hornblende schist unit of Brew and Grybeck (1984).
