Element transport and enrichment during propylitic alteration in Paleozoic porphyry Cu mineralization systems: Insights from chlorite chemistry

Chlorite is one of the most widely developed minerals in propylitic alteration around porphyry deposits and can be used to investigate element transport and enrichment processes during hydrothermal alteration. The Paleozoic Tuwu porphyry Cu deposit (metal reserve: 0.7 Mt Cu @ 0.67%), located in the southern margin of the Central Asian Orogenic Belt, is one of the most economical and largest porphyry Cu deposits in NW China. The Tuwu porphyry Cu...
