Geologic information

Identification information

Deposit ID 10003567
MRDS ID A106325
Record type Site
Current site name Unnamed

Geographic coordinates

Geographic coordinates: -171.21319, 63.41913 (WGS84)
Relative position This occurrence is in the bed of an unnamed stream that flows southwest to its mouth at Poowooliak Bay on the southwest coast of St. Lawrence Island. The mouth of this stream is 4 miles northeast of Poowooliak Point. The site is about 1 1/2 miles upstream of the mouth, just inland of the coastal wavecut platform. It was not included by Cobb (1972, 1980).

Comments on the geologic information

  • Geologic Description = Silicified, fine-grained volcanic rock exposed in the streambed contains pyrite and one rock sample contained 700 ppm zinc (Patton and Csejtey, 1971, p. C8, C15).
  • Age = The volcanic rocks here are mapped as part of a mid-Cretaceous assemblage but the age of mineralization could be Cretaceous or Tertiary, the age of volcanic and related hypabyssal intrusive rocks on western St. Lawrence Island (Patton and Csejtey, 1980).
