Economic information

Comments on the geologic information

  • Geologic Description = This occurrence is in bedded rocks of the Paleocene to Eocene Stepovak Bay Formation, near a small diorite or quartz diorite intrusion (Wilson and others, 1995). Wilson and others (1988) describe altered volcanic andesitic(?) breccia cut by a series of N 70 E-trending vertical shear zones. Some of the shears contain mineralized quartz veins. Alteration appears along shears and extends for approximately 600 feet along the beach east of the map site (Wilson and others, 1988). Rock samples collected by the U.S. Geological Survey in the mid-1980s were reported to be anomalous in silver, lead, zinc, arsenic, and bismuth (Angeloni and others, 1985; Wilson and others, 1988).
  • Age = Tertiary.
