摘　　要：河北省测鱼—内丘铜多金属成矿带位于大陆伸展构造环境下形成的甘陶河古裂陷槽,属中条山古裂谷系离石—阳泉古裂谷北东东延伸部分,是北东向中条山铜多金属成矿带的一部分。文章从成矿带地质背景、矿床地质特征研究入手,分析矿床成因,总结成矿模式。研究认为,成矿带韧脆性复合叠加断裂发育,控岩(绿泥片岩)、控矿特征明显,矿床具有层控特征,具多源、多期次叠加改造复成因特点。该成矿带找矿潜力很大,希望该研究工作对今后找矿具有一定指导意义。The Ceyu-Neiqiu copper polymetallic metallogenic belt is located in the Gantaohe palaeo aulacogen, which was formed in continental extensional tectonic environment. It belongs to the NNE-trending extensional part of Lishi - Yangquan palaeo rife, part of Zhongtiaoshan copper polymetallic metallogenic belt. On the basis of study on the geological background and geological characteristics of ore deposits, the deposit genesis was analyzed and the metallogenic model was summarized. The study resuhs indicated that ductile brittle composite superimposed faults is well developed in the deposit area, and the deposit has obvious characteristics of rock-controlling （chlorite schist） and ore-controlling, and strata bound features with multi-sources, multi stages of superimposed reformed activities. It is considered there is great potential for prospecting in this metallogenic belt, which has important guiding significance for the future prospecting work.
