Abstract

It is generally accepted that Cenozoic vertical motions of the African continent are controlled by convective circulation of the mantle. Despite recent advances, the temporal evolution of Africa’s ‘basin and swell’ topography remains poorly understood. Continental drainage net- works can be used to place constraints on the pattern of uplift through space and time. The shape of longitudinal river profiles is governed by uplift rate history and moderated by erosional processes, which can be calibrated with independent geological evidence, including marine terraces, volcanism, and deltaic sedimentation. My principal goal is to invert large numbers of these profiles to constrain the evolution of dynamic (i.e. mantle-supported) topography.
