On the basis of the comprehensive research of data and field work，the authors summarized the main gold types and geological characteristics in Democratic Ｒepublic of Congo． The results demonstrated that the gold deposits in DＲC can be classified as two types: ① placer gold，including alluvial and eluvial types，mainly distributed in the river and valley of Oriental，Maniema，North Kivu，and South Kivu provinces of DＲC． The ore- bearing layers located from ground surface to underground 2 m． ② greenstone belt gold deposit，broadly distributed in the centre of Central Africa gold zone，and extend to Central Africa Ｒepublic in NW trend and to Tanzania in SE trend． This type gold deposit is usually in large scale，and concomitanted with niobium and tantalum，and most of the orebodies located in the contact area of greenstone and Archean granites with sub- vertical shape． Fluids of ore- forming were mainly H 2 O- NaCl fluids rich in CO 2 ，which demonstrated that the fluid immiscibility was closely asso- ciated with mineralization，similar with other famous greenstone belt gold deposits in the world．
