滇－黔－桂微细浸染型金成矿带处于滇－黔－桂裂谷中。金矿床分布与深大断裂存在依附性。金矿带基本展布于深大断裂限定的三角区内，金矿床则分布于深大断裂旁侧或其交叉部位。由幔源岩浆岩（超基性岩及玄武岩）和幔源矿物沿深大断裂分布可推断，深大断裂延伸较深，可达上地幔，属超壳深大断裂。金矿床分布不受地层层位的限制，金矿化具有多层位成矿性。铅、硫、碳、氢、氧同位素地球化学综合对比研究表明，成矿热液中的矿质、矿化剂和水具深源与浅源的混合特征。热液成矿期矿石中石英及萤石的电子自旋共振（ＥＳＲ）定年结果为６８．４０±３２．４１Ｍａ，表明本区金矿床的成矿可能发生在燕山晚期—喜山早期。
Yunnan - Guizhou - Guangxi finely disseminated gold mineralization belt in Yunnan - Guizhou - Guangxi rift Valley. Gold deposit distribution and deep faults are dependent. The gold belt basically spreads in the triangular area limited by deep faults, while the gold deposits are located beside the deep faults or at the intersections. From the distribution of mantle-derived magmatic rocks (ultrabasic rocks and basalts) and mantle-derived minerals along the deep faults, it can be concluded that the deep faults extend deeper and reach the upper mantle, which belongs to the deep super-deep faults. The distribution of gold deposits is not limited by the stratigraphic layers, and gold mineralization has multi-layered mineralization. The comprehensive comparative study of lead, sulfur, carbon, hydrogen and oxygen isotope geochemistry shows that the mineralization, mineralization agent and water in the hydrothermal fluid are characterized by deep source and shallow source. Electron spin resonance (ESR) dating of quartz and fluorite in the hydrothermal ore-forming stage ore is 68.40 ± 32.41Ma, indicating that the gold mineralization of gold deposits in this area may occur in the late Yanshanian-early Himalayan period.
