| Deposit | DEPOSIT LIES JUST OUTSIDE NORTH RIM OF LAKE CITY CALDERA IN UNCOMPAHGRE CALDERA INFILL ROCKS CONSISTING OF EUREKA MEMBER RHYOLITE AND PICAYUNE MEGABRECCIA, COMPOSED OF CHAOTIC MASSES OF PRECALDERA INTERMEDIATE-COMPOSITION ROCKS INTERPRETED TO BE RESULT OF SLUMPING FROM OVERSTEEPENED CALDERA WALLS DURING INITIAL SUBSIDENCE OF UNCOMPAHGRE CALDERA. DEPOSIT IS TRANSVERSE VEIN IN SLACK'S (1980) QUARTZ/BASE-METAL ASSEMBLAGE, MIDDLE HYBRID ZONE. IN UPPER WORKINGS, VEIN DIPS 60 NW AND HAS FAIRLY WELL DEFINED WALLS WITH LITTLE OR NO CLAY SELVAGE. IN LOWER WORKINGS, VEIN DIPS CLOSER TO STRATIFICATION IN BRECCIA (ABOUT 45 NW) AND SPLITS INTO MANY PARALLEL AND INTERSECTING STRINGERS SEPARATED BY IRREGULAR SHEETS OF COUNTRY ROCK. WHERE VEINS RUN ALONG BRECCIA LAYERS, DEPOSIT APPEARS TO BE MORE OF REPLACEMENT TYPE. ORE SHOOTS PITCHED 30 NE ALONG STRIKE OF VEIN AND ARE SEPARATED BY GANGUE AND LESS ABUNDANT ORE. |
