| 摘 要： | 本文介绍了祁雨沟金矿床的成矿地质背景和矿床地质地球化学特征,讨论了矿床成因。通过含矿角砾岩体特征、矿物学、硫、铅、氢、氧同位素地质学和流体包裹体的研究,确定成矿物质主要来自下伏太古宇太华群;气液爆破角砾岩体为容矿构造;成矿作用是在中生代岩浆活动期后气液爆破-沸腾作用下完成的;成矿流体以岩浆水为主,混入部分大气水;矿床成因属岩浆热液矿床。

| Abstract: | In this paper，the authors has introduced the geological background of mineralization andgeology and geochemical features of Qiyugou gold deposit ，discussed the genesis of ore de-posit．Through the research on the feature of rock body mineralogy，S，Pb，H and O isotopicgeology and fluid inclusion of the ore—bearing breccia body，the authors conside that the ore—forming material mainly came from the underlying Taihua Group of Archeaneonothem. Gas—liquid explosive breccia body is the host structure．Mineralization went onunder the condition of gas—liquid explosion—boiling action after Mesozoic magmatic activitystage. Mineralizing fluid is mainly magmatic water，and mixed with part of meteorologicalwater．The genesis of ore deposit belong to magmatic hydrothermal deposit. |
