Abstract

Abstract

The rift systems in West and Central Africa that developed along the shear zone in Central Africa is a series of Mesozoic-Cenozoic rift basins, and their formation mechanism is still a matter of debate. The evolution of those rift systems has three stages, and Early Cretaceous is the most important one for the basin formation, in which the rifts and major fault zones were strongly active. Based on the geological setting of rift systems in West and Central Africa in Early Cretaceous, using linear elastic theory with two dimensional finite element numerical simulation, through the analysis of the stress field and the strain field, reliable evidence to the mechanical mechanism of rift systems are produced. The simulation results suggest that strike-slipping and extensional process coexist in African continent in Early Cetaceous, and the shear zone in Central Africa is not a "transform fault" but a structure that formed and developed simultaneously with the rift systems in West and Central Africa. In Mesozoic-Cenozoic Pangea disintegration period, due to the different motion rates of the three blocks along parallel slip vectors under the unified tectonic stress field and the counterclockwise rotation around WB by African plate, rift systems were formed and developed.
