East african rift valley uplift
WebThe actively splitting African Plate and the Arabian Plate meet in what geologists call a triple junction, where the Red Sea meets the Gulf of Aden. A new spreading center may be developing under Africa along the East African Rift Zone. When the continental crust stretches beyond its limits, tension cracks begin to appear on the Earth's surface. WebThe new plains formed at this time are known as the Post-African I erosion surface. Dissecting the northeastern highlands and plateaus are the rift valleys of the Zambia-Niassa Trough. These were formed by a combination of pre-Karroo folding and post-Karroo faulting and are an extension of the East African Rift Valley. The main trough floor ...
