Comments on the geologic information

  • Geologic Description = Chalcopyrite is present in phyllite interbedded with chert and volcanic rocks. Rocks are reported to be in the "cambrian-ordovician(?) neruokpuk(?) fm.".?? This occurrence is unlikely to be "Neruokpuk" as the term is currently used. Sandstone, not volcanic rock, is the dominant rock type of the "Neruokpuk Schist of Leffingwell (1919)" as mapped and used by Reiser and others ( 1980) and Lane and others (1995).
