摘要
The Bayuda area is located in Nile River State, North Sudan, in which one medium-sized gold deposit and seven exploration targets are located recently. This paper mainly deals with the geological conditions of gold deposits in Bayuda area, and the geochemical characters of ore and wall-rock of Hagagia gold deposit. The ore-forming process is divided into the hydrothermal, supergene weathering-sedimentary stages. The authors consider that the gold deposit in Bayuda area is formed by meso-epithermal metamorphic fluid and controlled by ductile shear zone and classified into orogenic-type gold deposit. The Proterozoic metamorphic rocks supply ore materials.
