Comments on the geologic information

  • Geologic Description = Miller and Grybeck (sample 7, 1973) collected a grab sample of gossan developed at a marble/schist contact at this locality. This sample contained 7,000 ppm As, 700 ppm Cu, 70 ppm Mo, 3,000 ppm Pb, 10,000 ppm Sb, and 10,000 ppm Zn. These occurrences are in Lower Paleozoic or Precambrian high grade metasedimentary rocks (Till and others, 1986).
  • Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
