Comments on the geologic information

  • GEOL.DESC: ORE BODY LIES ABOVE A GENTLY DIPPING CONTACT BETWEEN SILICEOUS WHITE FOLIATED, NONPORPHYRITIC RHYOLITE BELOW, AND MASSIVE TAN SOFT, PORPHYRITIC RHYOLITE ABOVE. MUCH OF THE RHYOLITE BELOW THE MINE HAS A STEEPLY DIPPING FOLIATION, LOCALLY THE ROCK IS PYRITIZED. SEVERAL TYPES OF PYROCLASTIC ROCKS ARE PRESENT, NONE SHOW BEDDING. ONE BED OF VOLCANIC BRECCIA IN LITTLE BACKBONE CREEK BELOW THE MINE IS COMPOSED OF A FELSITIC, GREEN CHLORITIC MATRIX CONTAINING 3 INCH OVAL BOMBS OF WHITE RHYOLITE WITH CLOSELY PACKED CHLORITE AND QUARTZ AMYGDULES.
