Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): LOCATED TO CENTER OF SECTION
Comment (Geology): FRANCISCAN ROCKS INCLUDE SHALES, SANDSTONES, CHERTS, CGL, AND GREENSTONE PLUS SERPENTINE THAT HAS BEEN ALTERED IN PLACES TO SILICA - CARBONATE ROCK. THE OVERLYING CRET ROCKS ARE SIMILAR TO THE FRANCISCAN SEDIMENTS BUT NOT AS BADLY CRUSHED. THE TERT BASALTS COVER OVER HALF OF THE DISTRICT AND HAVE BEEN HYDROTHERMALLY ALTERED WHERE THE ANDESITES HAVE INTRUDED IT. THE ANDESITIC EXTRUSIVE IS PREDOMINANTLY AGGLOMERATIC ALTHOUGH TUFFS AND FLOWS ALSO OCCUR. SEVERAL ANDESITIC INTRUSIVES HAVE BEEN MAPPED IN THE AREA. TWO RHYOLITE PLUGS HAVE BEEN MAPPED. FAULTS WITHIN THE DISTRICT TREND N TO NW. MOST OF THE MINERALIZED FAULTS ARE LESS THAN 2 MI LONG. THE ANTIMONY DEPOSITS ARE CINNABAR BEARING QUARTZ VEINS ON N TRENDING FAULTS IN THE BASALT, USUALLY WITH KAOLINIZED ROCKS. MERCURY MINERALIZATION IS ALSO FAULT CONTROLLED. IT IS LATER THAN AND MAY OR MAY NOT BE RELATED SPATIALLY TO THE STIBNITE. NO GENETIC CONNECTION CAN BE MADE BETWEEN THE VISIBLE VOLCANICS AND MINERALIZATION.
