Abstract: Potash resources are distributed unevenly on a global scale, and their reserves and output are mainly concentrated in a few countries and companies.Finding new supply sites for potash resources is an important task for China's geological exploration workers due to scarcity of potash resources in China.Africa, rich in potash reserves, predominantly harbours them in countries such as Congo(Brazzaville), Ethiopia, Eritrea, Egypt, Morocco, among others.Potassium formations are mainly from the Cretaceous, Neogene, and Quaternary periods.The geological conditions of potash mineralization in Africa are excellent.For instance, the arid and hot environment induced seawater evaporation, and extensional tectonics led to the formation of numerous fault depressions, and multi-stage transgression events provided good conditions for the eventual formation of potash reserves in Africa.Based on the analysis of the geological characteristics, deposit types and metallogenetic potential of typical potash deposits(occurrences) in Africa, it is considered that the North sub-Basin of the Gabon-Congo Basin in West Africa, the central area of the Danakil Basin in East Africa and the dry salt lake area in Northwest Africa are favorable areas for potassium exploration.
