In order to study the relationship between magmatic activity and mineralization, the authors analyzed the major and trace elements concentration and the characteristics of petrogeochemistry and petrogenesis of Wushanguan complex body based on the results of field work and petrographic studies. The major and trace elements concentrations were tested by XRF and  ICP-MS. According to the characteristics of major elements and trace elements, especially the discrimination diagrams, biotite-monzonitic granite is separately fractionated I-type granites and the granodiorite belongs to I-type granite.
