Abstract: Heerwusu lead-zinc deposit is a newly found deposit in the Shaolang River polymetallic metallogenic belt of the northern margin of the North China Plate, Inner Mongolia. The LA-ICP-MS U-Pb chronology and rock geochemistry of the biotite quartz diorite in the mining area are studied to reveal its petrogenesis, metallogenic background and contribution to the mineralization. The zircons of the biotite quartz diorite are euhedral-subhedral in shape and there is a clear growth loop inside. The Th/U ratio ranges between 0.43~1.20, indicating that it has the characteristics of magmatism. The dating results show that the samples were formed in the Paleozoic Middle Permian (268.1±2.6Ma). The rock geochemical analysis shows that the content of SiO2 is 59.23%~61.07%, Al2O3 is 16.24%~16.53% and the K2O/Na2O ratio ranges between 0.62~0.63. The distribution curve of rare earth elements is characterized by right inclining type with enrichment of light LREE, distinct differentiation of LREE and HREE,weak Eu loss (��Eu=0.84~0.90) and weak Ce anomaly (��Ce=0.91~0.94), indicating that there are few plagioclase in the source area. The primitive mantle-normalized trace element spider diagram also shows the enrichment of large ion lithophile element K, Rb, Ba and the loss of high field strength elements Nb and Ti, which have the "TNT" negative anomaly characteristics. The biotite quartz diorite in Heerwusu lead-zinc deposit is the product of the magmatism of the volcanic arc under compressional environment during Late Variscan of Middle Permian. The dynamic mechanism of its formation is influenced by the closure of the Paleo Asian Ocean.
