Subject category Comment text
Deposit NO SPECIFIC SITE DESCRIPTION AVAILABLE, BUT LOVERING AND GODDARD (1950) DESCRIBE GENERAL CHARACTERISTICS OF AREA DEPOSITS: "THE HYPOTHERMAL REPLACEMENT DEPOSITS ARE PERHAPS THE MOST WIDESPREAD OF THE PRE-CAMBRIAN ORE DEPOSITS BUT ARE NEARLY EVERYWHERE NONCOMMERCIAL. THE ORES COMMONLY OCCUR NEAR THE EDGE OF LARGE GRANITIC MASSES IN ACTINOLITE SCHIST OR OTHER LIMY BEDS OF (PRECAMBRIAN METAMORPHICS). THE ORE BODIES USUALLY CONSIST OF COARSELY CRYSTALLIZED AGGREGATES OF AMPHIBOLE AND CALCITE WITH MINOR AMOUNTS OF THE SULFIDE MINERALS, THE MOST ABUNDANT OF WHICH ARE CHALCOPYRITE AND PYRRHOTITE. IN SOME PLACES NICKEL AND COBALT MINERALS ARE ASSOCIATED WITH THE PYRRHOTITE AND CHALCOPYRITE, AND IN A FEW LOCALITIES SPHALERITE WITH MINOR AMOUNTS OF GALENA IS MORE ABUNDANT THAN CHALCOPYRITE...SOME OF THE BETTER-KNOWN DEPOSITS ARE THOSE ALONG THE SOUTH AND WEST SIDE OF THE TARRYALL MOUNTAINS JUST WEST OF THE PIKES PEAK GRANITE BATHOLITH..."
