摘要: 淘金冲金矿位于江南造山带的湘西地区，矿石类型主要为石英脉型和蚀变岩型，金属硫化物以黄铁矿为主，次为毒砂，脉石矿物以石英为主，围岩蚀变类型主要有硅化、黄铁矿化、毒砂化、绿泥石化和碳酸盐化。矿体主要产于新元古界板溪群五强溪组地层中，淘金冲–楼脚北东向断裂是主要的控矿断裂，密集节理带是淘金冲金矿的容矿构造。
Abstract: The Taojinchong gold deposit is located in the western Hunan area of Jiangnan Orogenic Belt. The ore types are mainly quartz vein type and altered rock type, the metal sulfide is mainly pyrite, the secondary is arsenopyrite, gangue mineral is mainly quartz, and the alteration types of surrounding rock are mainly silicification, pyritization, chloritization and carbonation. The ore bodies are mainly occurred in the Wuqiangxi formation of Banxi group. The Taojinchong-Loujiao fault is the main ore controlling fault, the joint zone is the ore-bearing structure of the Taojinchong gold deposit.
