  • Broad Nw Trending Fault Zone

Comments on the geologic information

  • FRANCISCAN SEDIMENTS AND SERPENTINE CONSTITUTE THE MAJOR ROCKS OF THE DISTRICT WHILE KNOXVILLE STRATA OCCUR E OF THE ORE DISTRICT. THESE ARE OVERLAIN BY PLEIOCENE - PLEISTOCENE SONOMA VOLCANICS WHICH ARE RHYOLITIC TUFFS AND AGGLOMERATES OF BASALT ANDESITE AND RHYOLITE. PRIOR TO THE UPPER PLEIOCENE THE ROCKS WERE FOLDED AND FAULTED GIVING MAJOR NW STRUCTURAL TRENDS. MANY OF THE MERCURY DEPOSITS OCCUR ALONG THE FLANKS OF A MAJOR ANTICLINE. THE SEDIMENTS HAVE BEEN HYDROTHERMALLY BLEACHED AND KAOLINIZED WHILE THE SERPENTINE HAS UNDERGONE SILICA - CARBONATION. ORE BODIES INCLUDE THOSE IN SILICA CARBONATE ROCK (MOST ABUNDANT), BODIES ALONG FAULTS IN FRANCISCAN SANDSTONE, OCCURRENCES ALONG CONTACTS WITH BASALT DIKES, AND BODIES IN BRECCIATED CHERT.
