|Location and accuracy||This occurrence is on the lower part of a stream entering the west side of Little Togiak Lake, 2 1/4 miles from the head of the lake. The map site is on the stream at an elevation of 100 feet, in the NW1/4 of section 8, T 7 S, R 58 W, of the Seward Meridian.|
Geologic descriptionEakins (1968, p. 13) collected several stream-sediment samples in this drainage that contained anomalous amounts of mercury and zinc. In addition, he found float of massive pods and veinlets of pyrite up to 3 inches thick in the stream. Bedrock along the stream includes several felsic dikes intruding argillite. Dikes and faults in the area generally trend east-west.
|Geologic map unit||(-159.192217996658, 59.5892536371954)|
|Mineral deposit model||Polymetallic veins (Cox and Singer, 1986; model 22c)|
|Mineral deposit model number||22c|
|Age of mineralization||Possibly Late Cretaceous or Early Tertiary. Mineralization may be related to the felsic dikes, which are inferred to be part of a regionally extensive Upper Cretaceous and Lower Tertiary plutonic suite (Hoare and Coonrad, 1978).|
|Workings or exploration||Reconnaissance stream-sediment sampling has been completed in the area (Eakin, 1968).|
|Indication of production||None|
Additional commentsThis occurrence is in Wood-Tikchik State Park.
