Comments on the geologic information

  • THE SHAFT WAS OPENED IN FELSIC VOLCANIC ROCK, POSSIBLY RHYOLITE, THAT HAS BEEN INTRUDED BY BLUE-GRAY GRANITE OR QUARTZ MONZONITE. THE INTRUSIVE CONTAINS PYRITE, CHALCOPYRITE (?) AND MAGNETITE. ROCKS NEAR THE CONTACT BETWEEN THE INTRUSIVE AND VOLCANIC ROCKS CONTAIN DISSEMINATED SULPHIDES. ALSO, NEAR THE CONTACT, THE IGNEOUS ROCKS BECOME FINE GRAINED AND XENOLITHS OF RHYOLITE OCCUR IN THE GRANITE NEAR THE CHILLED BORDER. THE VOLCANIC ROCKS ARE ALMOST COMPLETELY SILICIFIED BUT CONTAIN SOME RELIC STRUCTURES THAT MAY HAVE BEEN EITHER CRYSTAL OR LITHIC FRAGMENTS.
