| 中文摘要: |
| 选取黔西南大厂锑矿萤石为对象，开展流体包裹体和同位素地球化学研究。包裹体相态观察及显微测温结果显示，萤石的流体包裹体主要为气液两相包裹体和纯液相包裹体，包裹体测温结果显示成矿流体具有中-低温低盐度超高压的特点，表明成矿流体可能主要来源于深部。通过对大厂地区构造蚀变体同位素地球化学及产于黔西南构造蚀变体中典型金矿床同位素地球化学对比研究表明，成矿物质可能主要来源于深部，热液在上涌过程中混入地壳物质成矿。 |

| In this paper，fluorite of antimony fluid inclusion of Dachang antimony ore is selected to be the study target，the inclusion phase observation and micro-thermometry shows fluid inclusion in fluorite of Dachang antimony ore mainly are gas-liquid two-phase inclusion and pure liquid inclusion，the inclusion temperature test shows the mineral fluid has the characteristics of medium-low temperature，low salinity and ultra-high pressure，so the mineral liquid may come from deep area. By compare and study the altered body isotope geochemistry and altered body typical gold deposit isotope geochemistry in southwest Guizhou，it shows the mineral material may come from deep area，the hydrothermal upwelling and mix into the crust. |
