There are 63 transboundary river basins in Africa, covering 64 per cent of the continent’s land area (UNEP 2010). • - The distension margins often had early rift stages similar to the intracratonic grabens, preceding mass bending and break-up of the continental crust. Some of the sag basins, such as the Karoo, are clearly syn-depositional in origin, with clear evidence that subsidence was coeval with and exerted a strong control on sedimentation.
