摘　　要：通过研究黔西南金矿床时空分布及地球化学特征,讨论了深源流体参与金矿床成矿的可能性。金矿床在时空上受莫霍面隆起、深大断裂、幔源岩浆岩体的控制,且与航磁异常、重力异常、环形构造等存在对应关系。铅、硫、氢、氧同位素及稀土元素地球化学研究表明,成矿物质可能来源于深源流体及地层岩石;金矿床是深源流体改造地壳岩石的产物。According to the time and space distribution and geochemistry of gold deposits in southwestern Guizhou, in this paper is discussed the possibility of the participation of juvenile fluids in the gold deposit formation. The gold deposits are constrained by the uplift of the Moho, deep faults and mantle-derived magmatic rock bodies, and correspond in space with deromagnetic anomalies, gravity anomalies and circular structures. The study of lead, sulfur, hydrogen and oxygen isotopes and REE geochemistry indicates that the ore material might come from juvenile fluids and crustal rocks. The gold deposits are the product of reworking of crustal rocks by juvenile fluids.
