Comments on the geologic information

  • Geologic Description = Sphalerite and galena in widely scattered veins and replacements in hornfelsed and weakly propylitized siltstone, with subordinate greenstone and phyllite; sulfides present in 760 m by 1060 m area along ridge west of Galena Creek; more Zn than Pb in samples. Ag negligible; sulphides rare in phyllite, and malachite-staining common in greenstone. Older reports report presence of chalcopyrite in area. Geologic setting is structural dome containing Precambrian-Devonian siltstone, phyllite and greenstone which overly quartzite (possibly Neurokpuk Fm.) and are overlain by thick Devonian conglomerate (Kanayut and/or Kekiktuk Fm.) and Mississippian shale (Kayak Shale). Rocks intruded by Early Tertiary rhyolitic dikes; mineralization confined to greenstone-phyllite-siltstone unit; pyrite and Fe-oxides common along margins of rhyolite dikes (Barker, 1981, p. 33-40, 106-37).
