Comments on the geologic information

  • Geologic Description = Quartz-hematite (?) veins and gossan zones in marble are developed near a small fault (Gamble, 1988). A sample of gossan contained 20 % Fe, 1,100 ppm As, 270 ppm Zn, 80 ppm Sb, and 10 ppm Mo. A sample of the veins contained 1,400 ppm Zn and 250 ppm As. The marble is Lower Paleozoic in age (Till and others, 1986).
  • Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
