The Jigongcun molybdenum deposit, located in the middle of the Gangdese metallogenic belt in Tibet, is a quartz-vein type molybdenum deposit hosted in Qushui granodiorite batholith, with ore bodies controlled by the brittle reverse fault. In order to define the ore-forming time of Jigongcun molybdenum deposit, the authors selected five molybdenite samples for Re-Os isotope analysis. It indicates that the metals of the Jigongcun molybdenum deposit might have had a deep-seated magma source(the lower crust to the upper mantle), which experienced remelting from the delaminated lower crust heated by the mantle.
