摘　　要：在综合前人资料的基础上结合湘南及其邻区典型铋矿区的实际调查,将该区已知的原生铋矿床划分为与壳源改造型花岗岩有关的铋多金属矿床、与壳幔混熔型花岗岩有关的铋多金属矿床和与岩浆热液-热卤水叠加作用有关的铋多金属矿床三个成矿系列。前两个成矿系列包括辉铋矿-长石类、辉铋矿-石英类、辉铋矿-矽卡岩类和蚀变花岗岩型、云英岩型、石英脉型、磁铁矿-矽卡岩型、硫化物-矽卡岩型、斑岩型等;而后一成矿系列的矿床类型仅有碳酸盐岩一砂页岩组合类、似矽卡岩型。Based on summarizing regional data and practical investigation, the primary bismuth deposits in South Hunan and its neighboring area can be divided into three bismuth-polymetallic metallogenetic series respectively related to anatectic granite, syntectic granite and magmatic hydrothermal type superimposed by hot brine. The bismuth-polymetallic deposits related to granites can be subdivided into bismuthinite-feldspar type,bismuthinite-quartz type,bismuthinite-skarn type,altered granite type, greisen type, quartz vein type, magnetite-skarn type, sulphides-skarn type and porphyry type, and the bismuth-polymetallic series related to magmatic hydrothermal can be subdivided into carbonate-sandstone-shale type and para-skarn type.
