A new pattern of the tectonic units and metallogenic belts in Africa continent in terms of lithosphere

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. ©2022 China Geology Editorial Office.
