Preliminary Evaluation of Geochemical Data from the Proposed Chukchi Imuruk National Reserve, Alaska.
For Reference Only At Bureau Libraries :8 pages
Water and waterborne sediment samples from the proposed Chukchi Imuruk National Reserve were analyzed for the Bureau of Mines. The antimony, bismuth, gold, lead, silver, uranium, and zinc contents of the sediment samples were studied to determine if samples with anomalous element concentrations are present, to outline the distribution of the anomalous samples, and to evaluate the use of the geochemically anomalous samples, as indicators of known and potential zones of mineralization. Extensive uranium and zinc geochemical anomalies were identified in the southeastern part of the proposed reserve. Less extensive geochemical anomalies of gold and other elements were also identified. Some anomalous samples come from areas of known mineralization and suggest that the trends extending into the proposed withdrawal may have associated mineralization.
