Abstract:The Shuikoushan ore field is situated in the northern margin of the Nanling metallogenic belt. The ore field has abundant mineral resources including those rich in Pb, Cu, Zn, Au (Ag), U, Cd, In, Mn. The deposits are mainly of endogenetic type, but several exogenetic deposit are also present. The endogenetic deposits are include of Laoyachao Pb, Zn, Au deposits, Yagongtang Fe, Cu, Pb, Zn deposits, and Kangjiawan Pb, Zn, Ag, Au deposits. They are dated to between 160 to 150 Ma in the middle Yanshanian period. The exogenic deposits include examples like the coal measures occurring in the Douling formation of the Permian, and the Longwangshan weathering crust type gold deposits which were formed during the Hercynian and Yanshanian periods. From deeper to shallower sections, and from west to east, the Shuikoushan ore- field shows zonal characteristics of “porphyry type”- skarn- type- medium to low temperature hydrothermal metasomatic filling type- weathering crust type; the metallogenic element assemblages show a progressive trend in Fe, Cu, Pb, Zn- Pb, Zn, Au, Ag, U- Pb, Zn, Au (Ag)- Au. The formation of these deposits is closely related to the granodiorite and dacite porphyry ores in the Shuikoushan field. The polymetallic mineralization of Yanshanian middle- acidic (mainly acidic) magmatism related copper (iron), lead and zinc, gold and silver (uranium) in the ore field can be described as the Shuikoushan type, and is a typical part of the polymetallic mineralization related to the intermediate- acidic magmatism in south China. Based on this research the future deep ore- prospecting work in Shuikoushan ore field should focus onexploration of: 1) porphyry Cu polymetallic deposits in the deep- shallow granodiorite; and 2) deep and peripheral skarn- type Fe, Cu, Pb, Zn polymetallic deposits.
