Abstract: 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.
