  • Discontinuous Silicified Shear Zones

Comments on the geologic information

  • HEMATITE & MATNETITE AS REPLACEMENTS IN ONDESITE, AND DACITE ALONG NEAR VERTICAL SHEAR ZONE THAT STRIKES N75W. THE IRON WAS PROBABLY DERIVED FROM LOWER CRET. PLUTONIC ROCK, AND TRANSPORTED BY HYDROTHERMAL FLUIDS. (MUFFLER, 1964). REPLACEMENT WAS COMPLETE WAS COMPLETE ENOUGH ONLY IN A SMALL PART OF THE AREA, TO FORM ORE GRADE MATERIAL.
