Comments on the geologic information

  • Geologic Description = A small gossan in metacarbonate rocks contains limonite, cerussite and some galena. A grab sample assayed 6.3 % Pb (Mulligan, 1962). This is in high grade carbonate metamorphic rocks of probable lower Paleozoic age (Till and others, 1986).
  • Age = Cretaceous ; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
