摘　　要：钦杭成矿带东段是江西省最重要的成矿带。矿种有煤、铁、铜、铅、锌、金、银、钨、钼、锰、镍、锂、铌、钽、磷、硫、萤石、重晶石等。通过综合研究成矿带内16个主要矿产预测类型，从成矿时代、成矿作用、适用矿种的角度分析归纳各矿产预测类型特征，总结其主要预测要素，归属全国评价模型，初步构建钦杭成矿带东段（江西段）矿产预测类型谱系。认为该带各个地质历史时期均成矿，而180～148Ma的燕山期为主要成矿期，以岩浆热液及火山成矿作用为主，以沉积及变质成矿作用为辅。The eastern Qinzhou-Hangzhou metallogenic belt was the most important metallogenic beh in Jiangxi Province. Minerals in- cluded coal, iron, copper, lead, zinc, gold, silver, tungsten, molybdenum, manganese, nickel, lithium, niobium, tantalum, phos- phorus, sulfur, fluorite, barite etc. Through comprehensive study of 16 mineral prediction types, the authors analyzed the characteris- tics of mineral prediction types in lights of metallogenic epoch, mineralization, suitable ore sorts, summarized the main factors of pre- diction, belonging to the evaluation model of the whole country. The mineral prediction type spectrum was preliminary established. Re- search showed that each geological period in the belt was of mineralization, 180 - 148 Ma was the main metallogenic period （Yans- hanian）, dominated by magmatic hydrothermal and volcanic metallogenesis, and secondary as with sedimentary and metamorphic met- allogenesis.
