Reconnaissance geochemical studies in the Bristol Bay, Ugashik, and Karluk quadrangles, Alaska: A section in The United States Geological Survey in Alaska: Accomplishments during 1980

Geochemical reconnaissance studies in the Bristol Bay, Ugashik, and Karluk quadrangles were completed with collection and analyses of more than 1,200 stream-sediment and heavy mineral-concentrate samples during 1979 and 1980. At least two areas of possible metallic mineral occurrence have been delineated by results of the analyses, geologic fieldwork, and data provided by Bear Creek Mining Company.
