Deposit PITCHBLENDE OCCURS AS MASSES AND COLLOFORM COATINGS IN NE-STRIKING, SE-DIPPING, SHEARED, HEMATITE-STAINED, SULFIDE-BEARING QUARTZ VEINS CUTTING BIOTITE GNEISS. SULFIDES ARE SPARSELY DISSEMINATED IN AND ON MARGINS OF QUARTZ VEIN. OCCURRENCE DIFFERS FROM OTHERS IN GOLDEN GATE CANYON AREA IN THAT IT SHOWS NO CLOSE RELATIONSHIP TO CARBONATE-BEARING FAULTS. MINERAL DEPOSITION DID NOT PROGRESS FAR BEYOND PITCHBLENDE-HEMATITE PHASE, AS SHOWN BY RELATIVE SPARSENESS OF CU MINERALS AND ABSENCE OF POST-ORE ANKERITE. OCCURRENCE THUS MAY REPRESENT ONLY FIRST STAGES OF SEQUENCE OF METALLIZATION POSSIBLE FROM MINERALIZING SOLUTIONS.
