The Dexing area, northeastern Jiangxi province, China, is an important Cu—Au—Pb—Zn—Ag metals concentrating area. In this area, there are large scale Dexing porphyry copper orefield (includes Zhushahong, Tongchang and Fujiawu deposit etc.), shear zonerelated Jinshan gold deposit and subvolcanicrelated Yinshan Pb—Zn—Ag polymetallic deposit. These deposits can be divided into two types: shear zone host deposits and the magmatic—hydrothermal related deposits. These two types of deposits have different characteristics on the orecontrolling structures, ore forming elements assemblages, and the origin of ore forming fluids as well as the deposit geochemistry. It is suggested that these two types of deposits have no clear relations on genesis. The difference in ages indicates that they are formed in different stages of geological evolution. The shear zonehosted gold deposit was formed during the Neoproterozoic collision between Huaiyu terrane and Jiuling terrane, the matmatic—hydrothermal related deposits were the results of Jurassic subduction of Pacific plate. They are not the results of single magmatic—hydrothermal system.
