|Location and accuracy||This site is on the Alaska Peninsula about 0.6 mile north of inner Mitrofania Harbor. It is referred to as SBRGX-46 in Wilson and others (1988, locality 20). The map site is in the SE1/4 of sec. 30, T. 48 S., R. 60 W., of the Seward Meridian. The location is accurate to within 1 mile.|
Geologic descriptionThis occurrence is probably in a mudstone unit of the Upper Cretaceous Hoodoo Formation (Wilson and others, 1995). At this location hornfelsed mudstone crops out near hypabyssal andesite or dacite plugs and dikes (Wilson and others, 1988). Samples collected by the U.S. Geological Survey were reported to be anomalous in antimony, copper, and zinc (Wilson and others, 1988).
