Abstract

Planation surfaces are well pronounced in the topography of the Republic of Guinea-Bissau. They came into being during the Late Alpine macrocycle of the relief formation. Two planated surfaces belong to the African stage (Late Cretaceous-Oligocene) and are designated as Early and Late African respectively. Since Miocene a post-African pediplain formation begins which marks the epoch of global pediplanation. The process proceeded along with erosion and alluviation in river valleys. Early Africain surface remnants persist only in the South-East of the country. The Late African surface is widespread in eastern regions. Post-African pediplain can be found practically all over the country. - (L'A.)
