摘要
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。
BaSed on the study on time and space distribution and geochemistry of the fine-graineddisseminated gold deposits in southwest Guizhou province, the genesis of the gIod deposits isdiscussed in this paper. The gold deposits are controlled by Moho shape, deep faults and map-matic activities- The geochemical study of isotopes such as Pb、S、H 、 O and Ar indicates thatthe mineragenetic material sources came from juvenile fluids and crustaI rocks- The gold de-posits be1ong to the epithermal type, which were formed due to metasomatism of crustal rocksby hot juvenile fluids mixed with meteoric water.
