Geologic structures

Type of structure	Local
Structure description	THE OLDEST ROCKS OF THE DISTRICT ARE 200 M. OR SO OF BLACK SHALE WITH INTERBEDDED QUARTZITE, OF LATE JURASSIC AGE (PAMPAS FORMATION, SO CALLED). THEY ARE OVERLAIN BY MORE THAN 100 M OF WHITE QUARTZITE AND BLACK CARBONACEOUS SHALE, WITH COAL BEDS 50-150 CM THICK, OF EARLY CRETACEOUS AGE. THE SEDIMENTARY ROCKS ARE INTRICATELY FOLDED AND AT CAHUACONA AND NORTH AND EAST OF CHOQUEBAMBA WERE INTRUDED BY GRANODIORITE AND LATER BY ANDESITE. AT GRANODIORITE CONTACTS, SHALE MAY CONTAIN CHIASTOLITE PRISMS. THE ENTIRE DISTRICT LIES A FEW KM EAST OF THE CORDILLERA BLANCA GRANODIORITE APOPHYSIS OF THE COASTAL BATHOLITH. THE ORE DEPOSITS SEEM TO BE ZONED ROUGHLY AROUND THE ANDESITE INTRUSIVE OF CAHUACONA, WITH COPPER NEAR THE ANDESITE AND LEAD FARTHER OUT. ORE DEPOSITS ARE BANDED FISSURE VEINS WHICH TEND TO RAMIFY NEAR THE SURFACE AND CONTAIN LITTLE OR NO GANGUE.
