|Location and accuracy||This occurrence is on the Alaska Peninsula approximately 2,500 feet north of Anchor Bay. It is referred to as SBRGX-45 in Wilson and others (1988, locality 19). The map site is at an elevation of about 500 feet, 0.17 mile southeast of the top of hill 1040. The location is accurate to within 2,500 feet.|
Geologic descriptionThis occurrence is hosted by volcanic units of the Eocene to Oligocene Meshik Formation (Wilson and others, 1995). It consists of fractured and iron-stained volcanic flows cut by pyrite-bearing, vuggy quartz veins (Wilson and others, 1988). One sample collected by the U.S. Geological Survey is reported to contain anomalous values in arsenic and copper (Angeloni and others, 1985; Wilson and others, 1988).
