The Dongyuan W-Mo deposit, located in Qimen County in southern Anhui Province, is the largest W-Mo deposit in this region thus far reported. The deposit consists of Dongyuan, Xiyuan, and Jiangjia ore blocks. The W-Mo orebodies in Jiangjia and Xiyuan ore blocks are mainly occurred in granodiorite porphyry and the nearby contact zone, with the major type of veinlet-disseminated and disseminated mineralization. Based on tectonic patterns of lead isotope and related parameters, the lead isotopic compositions of Jiangjia (²⁰⁶Pb/²⁰⁴Pb=18.222 to 18.369, ²⁰⁷Pb/²⁰⁴Pb=15.579 to 15.618, ²⁰⁸Pb/²⁰⁴Pb=38.264 to 38.400) and Xiyuan (²⁰⁶Pb/²⁰⁴Pb=18.240 to 18.251, ²⁰⁷Pb/²⁰⁴Pb=15.604 to 15.618, ²⁰⁸Pb/²⁰⁴Pb=38.360 to 38.442) indicate that the metallogenic material is closely related to magmatism, and their leads are characterized by the source of lower crust and show crust-mantle mixing.
