Satelite View

Comments

Comment (Deposit): DEPOSITS IN THE CENTRAL DISTRICT ARE VEIN AND VEIN REPLACEMENT ZINC-LEAD-COPPER-SILVER ORE DEPOSITS. NUMEROUS FAULTS TRAVERSE THE REGION AND MINERALIZING FLUIDS FOLLOWED THE FAULTS. THERE WERE THREE PERIODS OF MINERALIZATION; MAJOR MINERALIZATION TAKING PLACE DURING THE SECOND PERIOD. ALL OF THE INTRUSIVE ROCKS HAVE BEEN HYDROTHERMALLY ALTERED. A CONCLUSION WAS DRAWN BY LASKY (1936, P.L) THAT EACH GENERAL PERIOD OF INTRUSION WAS FOLLOWED BY ROCK ALTERATION THAT PASSED AS A CONTINUOUS PROCESS INTO VEIN FORMATION.

Comment (Workings): THE MINES IN THIS DISTRICT WERE WORKED BY UNDERGROUND SHAFTS, STOPES AND DRIFTS.

Comment (Location): LOCATION IS ACCURATE FOR THE GROUNDHOG MINE. THE DISTRICT IS CENTERED AROUND THE COMMON CORNER OF T. 17, 18 S., R. 12, 13 W. THE TERM CENTRAL DISTRICT HAS BEEN APPLIED IN A BROADER SENSE TO INCLUDE THE FIERRO-HANOVER, FIERRO MANGANESE, GEORGETOWN AND SANTA RITA DISTRICTS. ; INFO FROM LAND.ST :1979; PREVIOUS QUAD DESIGNATION = FORT BAYARD (1947) 1:24000

Comment (Commodity): COMMODITIES AND ORE MINERALS LISTED NOT DEFINITELY KNOWN BUT BASED ON GENERAL OCCURRENCES REPORTED FOR DISTRICT

Comment (Location): LOCATION UNCERTAIN, BUT MINE APPARENTLY LIES ALONG UNNAMED TRIBUTARIES WEST OF LAKE FORK GUNNISON RIVER ABOUT 2 MILES SW OF WHITECROSS AND 1.3 MILES NW OF HANDIES PEAK. UNPATENTED CLAIMS REPORTEDLY EXTEND WESTWARD INTO SAN JUAN CO. ELEV AND LAT-LONG GIVEN ARE FOR POSSIBLE WORKINGS IDENTIFIED FROM AIRPHOTO EXAMINATION. ; INFO FROM LAND.ST :1977

Comment (Deposit): VEIN PROBABLY RELATED TO ONE OR MORE GENERALLY NE-TRENDING FAULTS WITHIN EUREKA GRABEN SYSTEM THAT CUT EUREKA TUFF AND ITS ASSOCIATED MEGABRECCIA IN SAN JUAN-UNCOMPAHGRE CALDERA INFILL SEQUENCE.

Comment (Workings): CDM REPORTS DESCRIBE WORKINGS AS 20-FT-DEEP SHAFT, 30-FT TUNNEL, 50-FT DRIFT EXTENDING DOWN FROM UPPER WORKINGS.

Comment (Commodity): MOST MINES OF DISTRICT EXCEPT PORPHYRY COPPER MINE CLOSED IN 1958 DUE TO PRICES. A MAJOR DISTRICT FOR CU, ZN, PB, AG, AU, AND MO (MCKNIGHT, 1960?, UNPUBLISHED DATA).

Comment (Development): THERE ARE NO OPERATING MINES IN THIS DISTRICT

Comment (Geology): THREE MAIN TYPES OF DEPOSITS: (1) CONTACT METAMORPHIC DEPOSITS IN LIMESTONE CLOSE TO IGNEOUS CONTACT; (2) COMBINATION OF FISSURE FILLING AND REPLACEMENT VEIN ON FAULTED CONTACT BETWEEN PORPHYRY DIKES AND SHALY LIMESTONE; AND (3) QUARTZ VEINS IN SHALE AND PORPHYRY, GRANODIORITE PORPHYRY STOCK, QUARTZ MONZONITE PORPHYRY SILLS, GRANODIORITE PORPHYRY DIKES, ALL LARAMIDE. (MCKNIGHT, 1960?, UNPUBLISHED DATA)

Comment (Deposit): THIS RECORD CONTAINS DATA FROM RECORD K002895 BY HELMUTH WEDOW WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
