Comments on the geologic information

  • GNESSIC GRANODIORITE AND GRANITE COUNTRY ROCK CONTAINS CHLORITE AND BIOTITE WITH SOME EPIDOTE FORMING DARK BANDS. PYRITE IS CONTAINED IN FRACTURES IN THE GRANITE. THE QUARTZ VEIN IS CLEAR TO MILKY AND BRECCIATED. MINERALS MOST COMMONLY ASSOCIATED WITH THE VEIN INCLUDE SIDERITE, SPECULARITE, CHLORITE, LIMONITE, HEMATITE, CALCITE, AND MALACHITE. THE SELVAGE IS COMPOSED PRIMARILY OF CHLORITE WITH CLAY MINERALS, ANKERITE, SERICITE, LIMONITE, AND EPIDOTE.
