Comments on the geologic information

  • GEOL.COM: FRANCISCAN ROCKS INCLUDE SHALE, MUDSTONE, AND SANDSTONE INTERBEDDED WITH ALTERED LAVAS (GREENSTONES) AND SERPENTINE. THE SERPENTINE IS HIGHLY SHEARED NEAR SEDIMENT CONTACTS. SMALL CHROMITE PODS MAY BE FOUND IN THE SERPENTINES. THE KNOXVILLE FORMATION IS UPPER JUR TO LOWER CRET, HOWEVER SOMETIMES THE UPPER BEDS ARE TERMED PASKENTA. KNOXVILLE BEDS ARE MORE SHALY AND BEDDING IS BETTER DEVELOPED THAN FRANCISCAN. OVER THIS IS A CGL. ABOVE THE CGL BEDS ARE MORE SANDY. TERTIARY VOLCANICS INCLUDE FLOWS, DIKES OF MAFIC COMPOSITION AND RHYOLITIC TUFFS. THE VOLCANICS ARE SOMETIMES MINERALIZED. MOST OF THE TUFFS HAVE BEEN SILICIFIED. HOT SPRINGS HAVE DEPOSITED SINTER BUT DO NOT YIELD MERCURY. SILICA CARBONATE ALTERATION OCCURS IN ALL THE MINES AND FORMED FROM HYDROTHERMAL REPLACEMENT OF SERPENTINE. CARBONATES, HOWEVER, OCCUR ONLY IN SMALL QUANTITY. THIS ROCK HOSTS MOST OF THE ORES. MOST FAULTS STRIKE NW, THE LARGEST BEING KNOXVILLE AND JERICO CREEK FAULTS. THE RARE
  • MINERALS REDINGTONITE, MILLERITE, AND GOLD HAVE BEEN REPORTED
