Chalcophile element fertility and the formation of porphyry Cu ± Au deposits [PDF]

Mineralium Deposita, 2018
Chalcophile element fertility, the chalcophile metal abundance in the source magma, is likely to be a critical factor for the formation of porphyry Cu ± Au deposits. In this study, we provide evidence to support this hypothesis by comparing the platinum group element (PGE) geochemistry of barren and ore-bearing Cu ± Au granitic suites.
