Comments on the geologic information

  • Geologic Description = An abandoned placer cut on a north bench just above the mouth of Nelson Creek exposes schist bedrock containing quartz segregations and boudins. A sample of boudined quartz and some enclosing schist assayed 0.02 ounces/ton Au, 0.10 ounces/ton Ag, 0.05 % Cu, 0.05 % Pb, and 0.05 % Zn (Herried, 1966, Table 1). Herried (1966) also reported this analytical result as $0.70 per ton gold (not 0.70 ounces/ton Au as restated by Cobb, 1975, and Hudson and others, 1977). The bedrock here is locally bleached and cut by a clay altered zone. Bedrock of the area is a metasedimentary schist and marble sequence of Lower Paleozoic age (Till and others, 1986).
  • Age = Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age. Some lode gold deposits on southern Seward Peninsula are mid-Cretaceous in age (see Midnight Mountain, BN047).
