摘　　要：Bambari绿岩带是一个太古宙花岗岩-绿岩带,位于刚果克拉通北部,呈北西向带状展布,长250 km,宽10-24 km.其主要组成岩性为太古宙花岗岩、条带状含铁建造（BIF）、角闪岩、绢云片岩、石英绢云片岩.在其东部的1/3地区已发现了一个大型的铁、金共生矿床,经对比研究认为,在Bambari绿岩带的中西部地区仍有重要的找矿意义.The Archean Bambari greenstone belt, located in the north of the Congo craton, trending northwest with a length of 250 km and width of 10- 24 km, is lithologically composed of Archean granite, Banded iron Formation（BIF）,amphibolite, sericite schist and quartz sericite schist. A large iron-gold associated deposit is found in the eastern part,covering 1/3 of the area. A comparative study concludes that, in the central and western area of the Bambari greenstone belt,it is still significant for prospecting.
