易门铜矿铜厂矿区矿床特征及控矿构造探讨

THE FEATURE AND A PROBE INTO THE STRUCTURE OF ORE CONTROL OF TONGCHANG OREFIELD IN YIMEN CU MINE

易门铜矿铜厂矿区的铜矿床多为热液脉型矿床,矿区内的矿体主要受不同类型的构造控制,其中北东向断裂带直接控制了矿体的形成和分布。因此,本矿区北东向断裂及各组断层交汇部位、岩石裂隙发育地段和褶皱轴部是重要的找矿靶区。

The Cu deposit of Tongchang orefield in Yimen Cu mine is mostly the hydrothermal veined deposit.The ore body is mainly controlled by the different structure,The NE fault zone controls directly the forming and distribution of orebody.Therefore,the NE fault,fault intersection,development area of rock fissure and fold axial part are all the important prospecting targets.
