Taca-Taca Alto porphyry copper deposit, province of Salta: Contributions to its knowledge
The Taca-Taca Alto porphyry copper deposit is located in western Puna, Salta Province, and is geneticaly related to an Oligocene volcanic sequence. Based on alteration-mineralization studies, three stages were recognized: 1. potasic alteration with magnetic-pyrrotite-pyrite-chalcopyrite-bornite-spha...
