Ore controlTHE HUACHOCOLPA DEPOSITS ARE EPITHERMAL TO LEPTOTHERMAL VEINS, MOSTLY OF SIMPLE MINERALOGY, COMPOSED OF, MAINLY, GALENA, SPHALERITE, AND CHALCOPYRITE IN A GANGUE OF QUARTZ, PYRITE, CALCITE, RHODOCHROSITE, BRECCIATED WALL ROCK, AND GOUGE. MOST OF THE VEINS
Geology
StructureTHE OLDEST ROCKS ARE A SEQUENCE OF 500 M OR MORE OF FINE-GRAINED THIN TO THICK-BEDDED GRAY LIMESTONE WITH SUBORDINATE GRAY, GREEN, RED OR BLACK SHALE; YELLOW TO BROWN MUDSTONE & MARL; & A BED 40-60 M THICK, OF GREEN TO REDDISH-GREEN MEDIUM-GRAINED QUARTZITE OVERLAIN BY SHALE & BASALT. THIS SEQUENCE IS OF JURASSIC AGE. THE BEDS ARE FOLDED ASSYMMETRICALLY OR OVERTURNED TO THE NE ALONG AXES TRENDING NNW. THE FOLDS ARE OF PRE-VOLCANIC AGE, AS THE OVERLYING ROCKS, FOR THE MOST PART, ARE ONLY SLIGHTLY FOLDED. IN THE SOUTHERN PART OF THE DISTRICT, BEDS OF TUFFACEOUS LIMESTONE, MARL, SILTSTONE & CHERT INTERBEDDED WITH ANDESITIC VOLCANIC ROCKS, ARE POSSIBLY EQUIVALENT TO THE CASAPALCA FORMATION OR CASAPALCA RED BEDS OF CENTRAL PERU, PRESUMABLY OF EARLY TERTIARY AGE., THE PRINCIPAL STRUCTURAL ELEMENTS OF THE DISTRICT-FOLDS IN THE JURASSIC LIMESTONE, FAULTS ALONG THE LIMESTONE-VOLCANIC CONTACT, AND MAJOR DIKES.
AlterationAT THE CONTACTS OF INTRUSIVE ROCKS, VOLCANICS ARE ONLY SLIGHTLY ALTERED; MAFIC MINERALS ARE CHLORITIZED & FELDSPARS ARE SERICITIZED & SAUSSURITIZED.
