摘要
The Shizishan ore field is the largest Cu-Au ore-field in the Tongling cluster, Anhui Province. According to the temporal and spatial relationship between mineralization and igneous intrusions, three ore types can be distinguished: stratabound skarn type, skarn type and hydrothermal vein type. The two skarn types are economically most important. Mineralization of the Shizishan ore-field relates to Hercynian and dominant Yanshanian magmatism. The geochemical characteristics of the rock show the magma coming from the mantle with mixing of high Na2O and K2O country rock by assimilate-contamination during the magma intrusion into the crust. Therefore, the different magma rocks have a relationship to the rock genesis.
