Comments on the geologic information

  • Geologic Description = The country rocks at this occurrence are sedimentary units of the Paleocene to Eocene Tolstoy Formation (Wilson and others, 1995). The occurrence is described by MacKevett and Holloway (1977) as an altered zone associated with Tertiary granitic rocks. U.S. Geological Survey mapping in the mid-1980s does not show granitic plutons in this area (Wilson and others, 1988). Samples of sedimentary rock collected in this area by the U.S. Geological Survey in the mid-1980's contained as much as 20 ppm copper, 20 ppm lead, and 80 ppm zinc (Angeloni and others, 1985).
