The Shangwan copper polymetallic ore deposit is a medium-sized porphyry-skarn copper polymetallic deposit in the city of Ruichang,Jiangxi Province,which was firstly discovered in the core of the Jieshou-Daqiao anticline developed in the Jiurui ore concentration district.This paper summarized the prospecting criteria based on analysis of the geologic features of the Shangwan copper polymetallic deposit.The result shows that the orebodies of the deposit occur as disseminated,fine vein disseminated and banded ores in the contact zones between granodiorite-porphyry and Ordovician carbonatic rock.Granodioriteporphyry was the parent rock for the skarn-type deposit,with the characteristics of high-alkali and high-K and crust-mantle mixing.It is concluded that the core of anticline and contact zones between Ordovician and Silurian are the prospecting targets for the deposits of this kind.
