Multiple mineralization events at the Jiru porphyry copper deposit, southern Tibet: Implications for Eocene and Miocene magma sources and resource potential

The Jiru porphyry copper deposit in the Gangdese Porphyry Copper Belt (GPCB) is hosted by monzogranite and monzogranite porphyry with SHRIMP U–Pb ages of 48.6 ± 0.8 Ma and 16.0 ± 0.4 Ma, respectively. Rhenium–Os ages of molybdenite from the monzogranite and monzogranite porphyry are 44.9 ± 2.6 Ma and 15.2 ± 0.4 Ma, slightly younger than ages of the host rocks, respectively. These geochronological data indicate that there are two mineralization...
