Lying in the north of Gandise-Nyainqentanglha magmatic arc, the Lietinggang deposit is a typical iron polymetallic deposit in the Gandise Pb-Zn-Ag-Cu-Fe metallogenic belt. Granodiorite and granite porphyry have a close metallogenic relationship with the Lietinggang deposit. The authors conducted LA-ICP-MS zircon dating of the granodiorite and granite porphyry, which yielded monzonitic granite age of 58.69±0.68 Ma and granite porphyry age of 60.69±0.98 Ma. The Lietinggang deposit was compared in metallogenic background with the ore deposits in Gandise-Nyainqentanglha magmatic arc, such as Jialapu, Sharang and Yaguila. With the underplating of mantle-derived magma during India-Eurasin continental collision, the series of deposits were formed in the main collision period. The zircon Lu-Hf of zircons from the Lietinggang deposit have εHf(t) values ranging from -3.01 to 3.0, and t_DM2 ages of Hf between 742 and 1 322 Ma, suggesting that the magma was from the mantle and the crust. The exploration achievements of the Lietinggang deposit show that the exploration of the iron polymetallic deposits in this region should be focused on the prospecting for Cu, Pb, Zn resources in the depth.
