| 中文摘要: |
| 祁雨沟金矿为典型的角砾岩型金矿床,矿体受角砾岩体的形态及断裂控制。矿床地球化学特征表明,金矿石微量元素含量变化复杂；稀土元素及硫、氢氧同位素资料显示,金矿成矿与区内花岗岩体有着密切的关系；矿石中的铅部分可能来源于上地壳浅源物质。初始成矿流体性质与岩浆热液、地下热卤水的性质相似。因此,认为祁雨沟角砾岩型金矿成矿物质具多源特点,但主要来源为燕山期花岗岩浆,部分为上地壳太华群变质岩系提供；成矿热液既非典型的岩浆水,也非典型的热卤水,而具多来源的特征,最可能的情况是岩浆水、热卤水和大气降水的混合来源。 |
| 英文摘要: |
| Qiyugou is a typical breccia-type gold deposit, and the ore bodies are controled by the breccia and fracture. The contents of trace element in ore are complex. The characteristics of rare earth elements and sulfur, hydrogen and oxygen isotope indicate that gold mineralization are closely related with granites. Part of Lead may derives from the upper crust. The initial ore-forming fluid is similar to magmatic hydrothermal or hot brine. It is consided that the ore forming material sources of Qiyugou deposit is multi-sources with mainly from Yanshanina granific magma and partly from the Taihua Group metamorphic rocks. Ore-forming fluid is neither typical magmatic water nor typical hot brine, but a multi-source mixed by magmatic water, hot brine and meteoric wathe. |
