Identification information

Deposit ID 10003568
MRDS ID A106326
Record type Site
Current site name Unnamed

Geographic coordinates

Geographic coordinates: -170.19317, 63.27915 (WGS84)
Relative position This site is on an unnamed stream that flows into the eastern part of Koozata Lagoon on the southcentral coast of St. Lawrence Island. The mouth of this stream is about 4 1/2 miles southeast of VABM Koozata. The site is almost 2 miles upstream of the mouth and is located within 1/2 mile. This site was not included by Cobb (1972; 1980).

Comments on the geologic information

  • Geologic Description = One stream sediment sample from this drainage contained 150 ppm tungsten, the highest tungsten value reported in stream sediments from St. Lawrence Island (Patton and Csejtey, 1972). However, other elements were not significantly elevated in stream sediments from this drainage. Bedrock in the drainage area is biotite quartz monzonite that at least locally intrudes Mississippian limestone (Csejtey and Patton, 1974, p. 43; Patton and Csejtey, 1980).
  • Age = If the one anomalous tungsten value is correct and reflects the presence of mineralization, this mineralization is probably mid-Cretaceous in age, the age of other biotite quartz monzonite plutons on St. Lawrence Island (Patton and Csejtey, 1980).
