黔西南微细浸染型金矿床在时空上受莫霍面形态、深大断裂及岩浆岩控制。铅、硫、氢、氧及氩同位素地球化学研究表明，成矿物质来源于深源及地壳岩石，成矿流体属深源流体与大气降水混合上升热流体。金矿床是这种热流体改造交代地壳岩石形成的中低温热液金矿床。
The fine disseminated gold deposits in southwest Guizhou are controlled by Moho morphology, deep faults and magmatic rocks in time and space. Geochemical studies of lead, sulfur, hydrogen, oxygen and argon isotopes show that the ore-forming materials are derived from deep source rocks and crustal rocks, and the ore-forming fluids are mixed up-going thermal fluids with deep source fluids and atmospheric precipitation. The gold deposit is a medium- and low-temperature hydrothermal gold deposit reconstructed from this thermal fluid to account for crustal rocks.
