摘　　要：将吉林省东部地区的贵金属、有色金属矿床在成矿作用时间上与全球性成矿事件及区域性成矿事件对比分析,总结成矿的相似性和本区成矿的特点及具中国特色的燕山期成矿的重要性,提出区内大型矿田(或矿集区)的空间分布特点及主控因素,对成矿预测具指导意义。Through the comparative analysis between the global metallogenic events of preci ous metal, nonferrous metal deposits and regional in mineralization period in th e eastern part of Jilin Province, we summed up the metallogenic similarity, char acteristics and the importance of the Yanshanian mineralization with the Chinese characteristic. Meanwhile, the distributive features of the large size orefie lds (a ggregate ore zone) in space and the main controlling factors are proposed in thi s paper, which have a guiding significance for the metallogenic prognosis.
