Deposit ID 10009560
MRDS ID D002605
Record type Site
Current site name Golovnin Bay

Geographic coordinates

Geographic coordinates: -162.92323, 64.51934 (WGS84)
Relative position This occurrence is on the northeast coast of Golovin Bay where outcrops of the Kachauik pluton are exposed (Till and others, 1986). This location is about 0.3 miles north of a coastal light and 1.5 miles northwest of the mouth of McKinley Creek. It is locality 135 of Cobb (1972, MF 445; 1978, OF 78-181); it is probably located within 0.5 mile.

Comments on the geologic information

  • Geologic Description = A heavy mineral concentrate from slope wash over intrusive rocks of the Kachauik pluton contained 0.074% equivalent uranium, primarily in an unidentied uranium-titanium-niobate mineral (West, 1953, p. 4). Other minerals idenitied in the heavy mineral concentrate included allanite, biotite, hematite, hornblende, ilmenite, magnetite, scheelite, and sphene. Most of these are probably assessory minerals in monzonite/syenite of the Kachauik pluton (Miller and others, 1972; Miller, 1972). However, parts of this pluton along nepheline syenite dikes locally contain up to 0.15% U3O8, 1.05% Th, and 2% REE (Miller and others, 1976). A K/Ar age for the Kachauik pluton is 99.9 +/- 3 Ma (Miller and Bunker, 1976).
  • Age = Mid-Cretaceous; a K/Ar age for the Kachauik pluton is 99.9 +/- 3 Ma (Miller and Bunker, 1976).
