摘　　要：水晶屯金矿区金矿化主要与黄铁矿化、硅化、绢云母化和钾长石化有关,矿体严格受断裂构造控制。通过对矿体硫同位素、氢氧同位素、矿物包裹体及控矿因素等方面的分析,推测其成矿物质来源于桑干群老变质地层及深源岩浆热液,成矿流体主要来自岩浆水,岩浆活动为矿体提供热动力;阐明了该矿的成因类型,认为水晶屯金矿是一个中—高温中浅成热液充填交代型金矿床。Mineralization in the Shuijingtun Gold deposit is mainly related to silicification,pyritization,sericitization and potassium alteration,and the ore-bodies are directly controlled by fault structure.According to analysis on surrounding rock and S,H and O isotope,mineral inclusions of the ore-body,and the ore-controlling factors of the mine area,we conclude that the ore-forming materials were originated from metamorphic rocks and deep-source magmatic rocks of Sanggan Group,and the fluid was mainly from magmatic water,and heating of ore bodies comes from magmatic activities,the deposit is a typical medium-low depth and mid-high temperature hydrothermal scouring replacement type gold deposit.
