Abstract The copper and gold polymetallic deposits in Dayaoshan area are dominated by porphyry type, skarn type and fault-altered rock type, with mainly gold, associated by copper, silver, lead and zinc mineralization which form a completed metallogenic series. Base on the study on the characteristics of deposits and their tectonic setting, two metallogenic series including four sub-series are defined in the area. The metallogenesis is closely related to shallow-ultrashallow igneous rocks. The magmatic movement provides heat source and hydrothermal fluid for ore-forming. The faults perform as migration path and control the distribution of ore bodies. The Sinian-Cambrian strata are major source beds of ore. A regional metallogenic model of source bed-structure-magmatism is established.
