Geologic setting

Geologic description

The rocks in the area of this occurrence are Paleozoic amphibolite-facies quartzite and amphibolite (Werdon and others, 2001). There is a high-angle, northwest-trending, strike-slip fault along Wall Street Creek that juxtaposes amphibolite-facies rocks on the northeast side of the fault with upper Paleozoic greenschist-facies metasedimentary and metavolcanic rocks on the southwest side. In 1968, Smith (1969) collected a quartz-rich rock sample (quartzite?) from here that assayed 3 percent zinc.
