Zircon U–Pb and molybdenite Re–Os geochronology and geochemistry of Jinchang porphyry gold–copper deposit, NE China: Two-phase mineralization and the tectonic setting

Whether multiple mineralization styles in porphyry deposits are the result of one or multiple pulses of magmatism is unknown. In this paper, we present new age and geochemical data on the Jinchang porphyry gold-copper (Au-Cu) deposit, an important deposit in NE China and in the eastern Central Asian Orogenic Belt (CAOB). Field geological study suggests that both the mineralization and ore-causative magmatism at Jinchang are multiphase. LA-ICP-MS...
