Comments on the geologic information

  • Geologic Description = This occurrence represents a group of four samples collected on the periphery of an altered silcic (silicified?) pluton intruding the Paleocene to Eocene Tolstoi Formation (Wilson and others, 1988; 1995). The northernmost of the four samples was from a basalt(?) plug or sill. The samples were collected by the U.S. Geological Survey in the mid-1980's and were reported to be anomalous in copper and zinc (Wilson and others, 1988).
