///The Bangpu Pb-Zn deposit, formed in the periphery of the porphyry mineralization body of the ore district, is a skarn deposit with relatively rich ore grade, and the ore-forming elements are dominated by lead and zinc, without copper basically. Main metal sulfides were objects of this study, and S and Pb isotopic methods were used to investigate the source of the ore-forming minerals. The results show that the δ³⁴S values of the ore metal sulfides have a wide distribution, and mainly vary in the range of -3.7‰~-0.7‰, with the characteristics of tower distribution, and that these sulfur materials were mainly derived from the magma. Lead isotopes of the ore have stable composition and are positive common lead. The high μ values of ore lead and the distribution characteristics of the data points in the evolution diagram of tectonic environment indicate that the ore lead was mainly derived from the upper crust.
