Comments on the geologic information

  • Geologic Description = Float specimens from this location contained molybdenite and powellite (?) in quartz (Smith, 1942). Hoare and Coonrad (1959) show a prospect symbol in a granitic stock at this location. The granitic stock may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska. The country rocks to the stock are clastic sedimentary rocks that may be part of the mid-Cretaceous Kuskokwim Group (Hoare and Coonrad, 1959) or possibly an older Paleozoic or Mesozoic section correlative with the Gemuk Group (Bundtzen and Laird, 1991).
  • Age = Cretaceous or Tertiary . The granitic rocks may be part of a Cretaceous or Tertiary igneous assemblage that is widespread through southwest Alaska.
