Economic information

Comments on the geologic information

  • Geologic Description = At this site altered pyritized dacite(?) intrudes sedimentary rocks of the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1995). Andesite sills and 3-inch-wide quartz veins were also reported in the area (Wilson and others, 1988). Seven samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in arsenic, copper, gold, and lead (Wilson and others, 1988).
  • Age = Paleocene or younger.
