摘　　要：中条裂谷位于山西省南部,华北地台南缘,是我国重要的铜矿集中区。区内成矿地质作用复杂,铜矿类型多,成矿地质条件优越。文章通过分析成矿地质构造背景,探讨了裂谷演化过程中各分支的不平衡发展,在裂谷的不同构造部位分别形成了不同类型的铜矿床,其南西支以海底喷流铜矿(SEDEX)为主,南东支为海底火山喷流沉积作用形成的铜铁矿床(VMS),两分支交汇部位则为岩浆热液成矿作用形成的斑岩型铜矿。结合近几年地质大调查项目工作成果,运用裂谷成矿理论,分析了成矿规律,提出了成矿远景区。The Zhongtiao mountain, with several type deposits, and nice mineralization potential and complicated geological action, is one of the major copper ore deposit areas in China. On the basis of analyzing geological and tectonic background and unequilibrating development of braches of rift during evolution, the it is suggested that different type deposits were formed in different location of tectonic location of rift in this paper, that means, the sedimentary exhalative （SEDEX） type cupper deposits formed in the south - west branch, volcanogenic massive sulfide （VMS） cupper and iron deposits were formed in the SE branch and the porphyry type cupper deposits were formed in the junction location between two branches. Summarizing the geological survey of previous years using mineralization rift, I analyzed the metallogenesis regularity and proposed the prospective area for exploartion.
