  • Silicified Zones

Comments on the geologic information

  • THE MINE WAS OPENED IN QUARTZ STRINGERS ASSOCIATED WITH SILICEOUS ZONES IN SERICITICALLY ALTERED ARGILLITE. THE VEINS ARE MILKY QUARTZ WHICH IS IRON STAINED AND CONTAIN VUGS LINED WITH MANGANESE OXIDE. SHEARED PHYLLITE CROSSCUT BY QUARTZ VEINLETS FORMS THE COUNTRY ROCK ADJACENT TO THE QUARTZ VEINS AND SILICEOUS MATERIAL. GALENA, SPHALERITE AND CHALCOPYRITE HAVE ALSO BEEN REPORTED.u A SYSTEM OF DISCORDANT STRINGERS IS REPORTED TO TREND N 33 W AND DIP 57u DEGREES TO THE NORTHEAST.
