摘要
Based on the comprehensive study of geology and geophysics in African continent,three types of lithosphere(craton-type,orogenic-type and rift-type)can be identified.Considering lithosphere discontinuities as the boundary,two first-order tectonic units(mainly cratonic-type in the west and rift-type in the east)are proposed.Different types of lithosphere can be divided into secondary-order and third-order structural units,and the blocks within lithosphere can be further divided into fourth-order structural units.The geological history,the formation process and significance of different types of lithosphere in African continent are briefly discussed.
