| 摘 要： | 黔东同古金矿床产于元古界下江群浅变质岩系中，矿体严格受构造控制，矿体划分为层间脉型、破碎带型和网脉型3种类型，矿石贫硫化物。通过对同古金矿床流体包裹体的成分、氢氧同位素及包裹体CO2的碳同位素特征研究分析，认为同古金矿床主成矿阶段的成矿流体是以大气降水为主的富含CO2的弱酸、弱还原混合地热流体。

| Abstract: | Located in eastern Guizhou, Tonggu gold deposit occurs in epimetamorphic rock series of Proterozoic Xiajiang group. The ore body which is strictly controlled by tectonic can be divided into three types, intercalated vein, alteration terrane and network vein. The sulfide in the ore is infrequent. By analyzing the fluid inclusion component, H/O isotope and the C isotope of the CO2 inclusion, the paper shows that the metallogenic fluid of the main metallogenic period of Tonggu gold deposit is a kind of weak acidic and weak reductive mix-geothermal fluid which consists mainly of CO2-rich atmospheric water. |
