Comments on the geologic information

  • Geologic Description = The country rocks at this site consist of Tertiary andesitc flows and volcanic breccias, and sandstone and shale. The sedimentary rocks may belong to the Paleocene to Eocene Tolstoi Formation. The volcanic rocks are part of an undivided Tertiary sequence (Wilson and others, 1995). Rock samples collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in antimony (Wilson and others, 1988).
