摘　　要：集安南部鸭绿江成矿带上分布有众多的金及多金属矿点,特别是本区所产出的金矿床(点),多与中元古代碱长花岗岩体关系密切。本文针对这一特点,从分析中元古代碱长花岗岩入手,针对集安南部的碱长花岗岩体、与之相关所产生的早元古代地层的褶皱及其所产生的一系列褶皱构造等特点,进而分析了本区金成矿地质条件,提示了集安南部鸭绿江成矿带上是寻找与中元古代碱长花岗岩体有关的金矿床的理想场所。There are many gold and polymetallic ore spots in the Yalujiang metallogenic belt of the southern part of Ji an region of Jilin Province,specially,gold deposits(spots),most of them are associated with Mesoproterozoic alkali granite.On the basis of the stratigraphic fold and structural characteristics,analyzed metallogenic condition in the study area,it is verified that Yalujiang metallogenic belt of the southern part of Ji an region of Jilin Province is a satisfying metallogenic belt.
