Geologic information

Identification information

Deposit ID 10307269
Record type Site
Current site name Unnamed (northwest of headwaters of Humbolt Creek)

Geographic coordinates

Geographic coordinates: -164.51342, 65.81933 (WGS84)
Relative position This occurrence is on a level spur, at 2,000 feet elevation, 1,000 feet northwest of the upstream termination of the west headwater tributary of Humbolt Creek. Humbolt Creek is a northeast-flowing tributary to Goodhope River. This location is 2,000 feet north of the continental divide and 5,000 feet north-northwest of ARDF locality BN048.

Comments on the geologic information

  • Geologic Description = Till and others (1986) show bedrock here to be part of a polydeformed metapelitic schist that may be Precambrian in age. Sainsbury and others (1970) indicate that rusty and quartz-veined metasedimentary rocks are present over parts of this ridge spur. This and other nearby altered zones (BN048, BN050, BN052) have been interpreted to be localized along normal faults (Sainsbury and others, 1970) that are structurally above subsurface parts of the Oonatut Granite Complex (Hudson, 1979) which outcrops 11,000 feet to the northwest. Samples of rust-stained quartz veins and brecciated quartz veins contain 0.02 to 0.06 ppm Au and up to 500 ppm As (Sainsbury and others, 1970, Table 2). Base metals were only weakly to moderately anomalous in these samples but two had tin contents of 200 ppm. The Oonatut Granite is part of the western Seward Peninsula tin granite suite (Hudson and Arth, 1983).
  • Age = Probably Late Cretaceous; this occurrence may be associated with emplacement and crystallization of the Oonatut Granite Complex. K/Ar ages for the Oonatut Granite Complex are about 70 my (Hudson, 1979).
