Metallogenic conditions and prospecting potential of the Zhashui-Shanyang poly-metal ore cluster

Abstract：The Zhashui-Shanyang basin is developed with hydrothermal sedimentary rocks and flysch formation, which were reworked by strong magmatism and faulting. The basin has good ore-forming conditions and is now an important ore-cluster area. To date, remarkable Ag-Pb-Cu-Zn deposits have been found in Devonian carbonate strata, with numerous no-evaluated geochemical anomalies, indicating that the basin is potential for ore exploration. In this paper it is suggested that the reworked hydrothermal sedimentary type poly-metal deposit, albite breccia type gold deposit, metamorphosed sedimentary type magnetite deposit, and porphyry-skarn type copper (molybdenum) deposit can be found in the Yindongzi-Tongmugou siderite-Ag-Pb-Zn-Cu-Au belt, Dongchuan-Xiaochuan Pb-Zn-Cu-Au belt, and the Cu-Au-Ni(Co)-Mo metallogenic belt along the Fengzhen-Shanyang fault. Particularly, the Gangou-Waizhanggou-Shuangyuangou-Tudigou area in north side of the Fengzhen-Shangyang fault, the Lijiabian-Nengshuigou-Zhangshigou area in the south side of the Fengzhen-Shangyang fault, and Mujiazhuang-Xiaotai area can be targeted for copper exploration. The areas surrounding or beneath the campus of the Mujiazhuang Cu deposit and Yindongzi Ag-Pb-dominated poly-metal deposit are favorable for new deposits or orebodies.
