Comments on the geologic information

  • Geologic Description = Thick Quaternary glacial deposits and Upper Tertiary sedimentary strata cover most of the older bedrock in this area. Regionally, the main geologic feature is the northeast-trending Chulitna fault, which separates a sequence of Upper Jurassic to Upper Triassic(?) crystal tuff, argillite, chert, graywacke, and limestone on the north, from Upper Devonian to Lower Triassic volcanogenic and sedimentary rocks on the south. Faulting and shearing of the rocks has occurred, along with intrusions of Late Cretaceous dikes and stocks. As reported by Capps (1919), the Center Star prospect consists of arsenopyrite, pyrite and chalcopyrite disseminated in bluish dike rock.
  • Age = Possibly Late Cretaceous or younger.
