Comments on the geologic information

  • GEOL.DESC: 4 MAIN VEINS CONTAIN BLACK MANGANESE OXIDES; CALCITE AND WALL ROCK FRAGMENTS, AND ARE ENCLOSED IN COUNTRY ROCK OF DARK GRAY LAVA, PROBABLY ANDESITE. MANGANESE OXIDES, MAINLY PSILOMELANE, HAVE PECULIAR STOLACTITIC STRUCTURES OF MINUTE CYLINDRICAL RODS AND SERIES OF WAVY PLATES. TWO PERIODS OF MINERALIZATION OCCURRED; DEPOSITION OF MANGANESE IN FISSURES AND THEN DEPOSITION OF CALCITE IN REOPENED FISSURES, LEAVING RUGS WHICH WERE FILLED BY EROSION PROCESSES.
