Mesozoic Tectonism in Northeast Africa

Mesozoic tectonism in NE Africa was locally, but significantly, impacted by older Neoproterozoic and Hercynian structures. During the Permo-Triassic to Neocomian, the dominant control on deformation was the newly formed Neotethyan margin to the north. From the late Aptian onward, stress fields represented the combined effects of distant plate boundaries, producing both extensional and compressional deformation.
