湖南耒阳铅门冲铜锡多金属矿床地质特征及找矿前景

Analysis of the Geological Characteristics and Prospecting Potential of the Copper-Tin Polymetallic Deposit in Qianmenchong

在讨论铅门冲铜锡多金属矿成矿地质背景基础上,对其矿床地质及矿床地球物理、地球化学特征进行研究。矿体赋存于接触带和碳酸盐岩及碎屑岩类中,严格受岩体接触带或断裂构造控制。矿床成因类型为接触交代型和岩浆热液充填交代型,同时指出找矿标志,分析了找矿远景及今后工作方向,对该区以后的找矿工作有一定的指导意义。

The deposit geology and geophysics,geochemistry of the copper-tin deposits in Qianmenchong are studied on the basis of discussion on the background of metallogenic geology.Ore bodies occur in the contact zones and carbonate rocks and clastic rocks,and are strictly controlled by the contact zones or fracture structures.The genetic types of ore deposits are contact metasomatism and magmatic hydrothermal filling metasomatism.Meanwhile the prospecting criteria are pointed out,the prospecting potential and future work direction are analyzed which may have certain guiding significance for the future work.
