Comments on the geologic information

  • Geologic Description = The Competition Creek prospect is a syngenetic, sedimentary deposit of sulfide disseminations and lenses predominately of pyrite and marcasite, along with some galena and sphalerite. The deposit is in the black shales and cherts of the Kuna Formation (J. Britton, oral communication, 1998). Barite occurs in a shale horizon below the mineralized horizon. In this area, a mafic sill intrudes the Kivalina limestone and shale. The sill is highly propylitized, but appears to have been diorite or gabbro (Moore and others, 1986). The stratigraphic setting at Competition Creek is similar to that at Lik (ARDF number DL005).
  • Age = Mississippian to Triassic. A potassium argon date indicates that the deposit is Late Mississippian in age.
