湖南香花铺矿区钨铅锌矿床地质特征及控矿因素

湖南香花铺矿区钨铅锌矿床位于香花岭矿田南部,尖峰岭岩体东侧,矿区北东向、近南北向构造断裂十分发育,其成矿条件十分优越。通过对香花铺钨铅锌矿床地质特征及控矿因素的研究,分析认为地层、构造、岩浆岩对矿床的形成起了不同的控制作用,成矿物质主要来源于岩浆岩,断裂构造提供了矿液运移通道,断裂构造及层间裂隙提供了容矿空间,具高—中温热液充填交代型矿床特征。矿区矿床类型为构造裂隙热液充填交代型和岩体外接触带层间(节理)裂隙热液充填交代型。

Geological characteristics and ore-controlling factors of tungsten-lead-zinc deposit inthe Xianghuapu mining area, Hunan

The tungsten-lead-zinc deposit of Xianhuapu mining area is located in the south of Xianhualing ore field and the east of Jianfengling rock mass. Tectonic faults are well developed in the north-east direction and near south-north direction, and the metallogenic conditions are superior. Through the study of geological characteristics and ore-controlling factors of the Xianghuapu tungsten-lead-zinc deposit, it is concluded that strata, structure and magmatic rocks play different controlling roles in the formation of ore deposits. The ore-forming materials mainly come from magmatic rocks, and the fault structure provides channel for mineral fluid migration. The fault structure and interlayer fissures provide ore-hosting space and have the characteristics of high-medium temperature hydrothermal filling metasomatic type deposits. The deposits are of the hydrothermal filling metasomatism type of tectonic fractures and the hydrothermal filling metasomatism type of interlayer (joint) fractures in the contact zone of rock mass.
