Comments on the geologic information

  • Geologic Description = Asher (1869, DGGS R18) reported surface float of finely crystalline galena in quartz at this locality. Briskey (1983) identified stringers and disseminations of chalcopyrite and malachite in schist and in quartz bands in schist here. Bedrock is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
