Comments on the geologic information

  • Geologic Description = Marble interlayered in pelitic schist forms outcrops just east of the Nome-Taylor road. Sainsbury and others (1969) describe replacements of marble by banded, fine-grained silica containing pyrite and traces of chalcopyrite. Although mapped as klippe by Sainsbury and others (1969), the marble is interlayered with schist and part of a low grade, Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
  • Age = Unknown but possibly Cretaceous; the major episode of epigenetic mineralization on Seward Peninsula accompanied higher temperature metamophism and mid- to Late Cretaceous granitic plutonism in the region.
