This is one of a series of reports that describe mineral assessments of certain lands in Alaska. The study region includes 2.15 million acres in Selawik National Wildlife Refuge proposed by the U.S. Department of the Interior in February 1978 and nearby areas. Bedrock and visual evidences of mineralization are covered by vegetation, sediments, streams, and lakes, except in marginal uplands near the north and south borders. Regional geophysical work indicates that at least part of the south side of the study region may be underlain by granitic rocks. Where exposed, some of these granitic and associated rocks contain uranium. Other mineral elements that commonly occur with granites such as copper, lead, zinc, molybdenum, tin, tungsten, silver, gold, fluorine, and thorium may also be present.
