Surfaces of planation at NW («LOW») Africa and Atlas

Abstract

Dominant surface on Pre-Cambrian and Lower Paleozoic rocks (described as «Post-African» and in some places as «African» surface by L. King) is proved to be not Cenozoic but Mesozoic (Post-Gondwanian) planation surface. African and Post-African surfaces are widespread only within areas composed with loose Mesozoic and Cenozoic deposits. Quantity and age of planation surfaces of Africa are the same as those in Europe, Asia, Australia, which can be accounted for by dependence of planation surfaces formation on global eustatic transgressions of the Ocean.
