Geologic descriptionPyritic zones are abundant on the western one-third of Amchitka Island. Pyrite in quantities up to one-third of the volume of the rock occurs in volcanic rock of the Amchitka Formation and in sedimentary rocks of the Banjo Point Formation (Powers, 1960, p. 541). The pyrite mineralization tends to follow zones of fractures of diverse strike. One sample assayed trace copper, lead, and zinc.
