In the latest Cretaceous, the recorded high sedimentation rate
was synchronous with a basal conglomerate recorded at the Santonian/
Campanian transition which indicates a tectonic uplift
affecting the source areas during that time. This event is described
in many parts of Africa and known as the Santonian tectonic pulse
(83 ± 2 Ma) attributed to the onset of the collision between the
AfricaneArabian and Eurasian plates
