摘　　要：通过对研究区铜矿的控矿构造研究,划分出7种构造控矿类型,探讨了构造叠加成矿,提出“神农期”和“晋宁期”的NW向构造使铜元素初始富集,“加里东末期”的古NNE向构造对铜矿形成起主要改造富集作用,在此基础上建立了该区铜矿的构造控矿模式。Based on analyses of structural styles, the ore-control structures in copper orefields of the Shennongjia area can be divided into seven types. The author in this paper approaches the evolution history of regional structures controlling copper deposits, proposes a structural ore-control model and makes a conclusion that the NW-striking structures ('Shennong Period' and 'Jinning Period') initially caused the enrichment of copper, while the Late Caledonian NNE-striking structures played a leading role for enrichment of copper through reformation.
