The Jinzhai moyite intrusion locates in the North Huaiyang tectonic zone of Dabie orogenic belt. It was dated to be 129.7±1.5 Ma by LA-ICP-MS zircon U-Pb method, which belongs to the early Cretaceous magmatism. Also, there are several lead-zinc mineralization occurences around the Jinzhai intrusion, which identify with the regional magmatism and mineralization. The intrusion is characterized by high SiO2 contents（SiO2=72.47%～77.80%）, high alkali contents（K2O+Na2O=7.48%～8.16%）, but low CaO contents （0.15%～1.47% ）. The moyite is marked by a “sea-gull”pattern of REE distribution with a δEu ranging from 0.18 to 0.40, showing relatively significant negative Eu anomaly. These rocks enrich in Ga （21.68×10-6～24.12）, Zr （127.68～196.75）, Nb（33.31～60.53） and Y（14.57～27.51）, but deplete in Sr（8.15～138.52）and Ba contents （23.04～332.63）, and remarkably exhibit negative Ba，Sr，P，Eu and Ti anomalies on the primitive mantle-normalized trace element diagram. All these characteristics resemble it is A-type granite, and it may be the product of partial melting of lower crust source rock. Jinzhai moyite is the plate A1-type originated in post orogenic extension environment, which is the alkaline granite that didn’t generate in anorogenic tectonic background.
