Identification information

Deposit ID 10307265
Record type Site
Current site name Unnamed (along Kougarok River)

Geographic coordinates

Geographic coordinates: -164.8014, 65.67932 (WGS84)
Relative position This location is for bedrock exposures in old placer workings on the west side of the former cummunity of Taylor. Taylor is located at the end of the Nome-Taylor road, on the west bank of Kougarok River, about 1,000 feet south of the mouth of Taylor Creek. This is locality 6 of Gamble (1988)

Comments on the geologic information

  • Geologic Description = Graphitic metasedimentary rocks, exposed in old placer workings, contain numerous hydrothermally altered zones with fractured quartz veinlets and abundant pyrite (Sainsbury and others, 1969, p. 30). A sample of ribbon quartz contained 200 ppm As and a pyrite-rich pan concentrate from the altered zones contained 1.3 ppm Au, 2 ppm Ag, greater than 10,000 ppm As, 750 ppb Hg, 200 ppm Co, and weakly elevated base metals (Sainsbury and others, 1969, p. 39).
  • Age = Unknown but possibly Cretaceous; if gold-bearing lode structures are present here they may be similar in age to some lode gold deposits of southern Seward Peninsula. The southern Seward Peninsula lode gold deposits formed as a result of mid-Cretaceous metamorphism (Apodoca, 1994; Ford, 1993, Ford and Snee, 1996; Goldfarb and others, 1997) that accompanied regional extension (Miller and Hudson, 1991) and crustal melting (Hudson, 1994). This higher temperature metamorphism was superimposed on high pressure/low temperature metamorphic rocks of the region.
