Abstract

Abstract

The East African Rift is the most typical continental rift in the world.Ⅰt is generally believed that the rift consists of two parts:the East Branch and the West Branch.By summing up the previous research results,this paper discusses the relationship between the evolution of the East African Rift and the mantle plume in terms of geophysics,petrology and geochemistry.The models correspond to magmatism with different geochemical properties in northwest Ethiopia and Turkana,respectively.Finally,the possible patterns of the mantle plume under the East African Rift were discussed.
