摘要: 柏坊铜矿位于耒阳临武南北向褶皱带与衡阳断陷盆地的交切部位,属不同构造迭加复合部位。本文对矿区宏观地质特征,岩矿石岩相学特征、地球化学特征进行分析,认为区内下白垩统神皇山组(K1s)地层及F22断裂构造对成矿有十分重要的作用,砂岩参与到了辉铜矿矿石的成矿作用过程中并提供了部分的成矿物质,铜矿体形成后还受到了地下热卤水的改造作用,并认为该矿床属于沉积–改造型铜矿床。
Abstract: Bofang copper deposit is located in the intersection of Leiyang-Linwu south-north trending tectonic belt and Hengyang fault basin, which belongs to the superimposed part of different geological structure. Based on the macro geological characteristic, petrographic and geochemical analysis, it is thought that the Shenhuangshan group and F22 fracture play important roles to the mineralization. It turned out that chalcocite ore not only participated in the mineralization but also offered part of the ore-forming materials. It is indicated that copper body is formed by the superimposition and alteration mineralization of underground geothermal brine. Bofang copper deposit belongs to sedimentation-reworked deposit.
