Considerações sobre o cenozoico de Angola, África

Abstract

The Cenozoic sedimentary deposits of Angola were affected by several changes in the regional base level, uplifts and drainage downcuttings, associated to climate oscillations. The Tertiary fluviatile, fluvio-deltaic and desertic sedimentary deposits of southwestern Angola, the marine Quaternary cover of the Moçâmedes, Benguela and Cuanza Mesozoic - Tertiary and the several Kalahari Formation (T) reworking cycles of northeastern Angola, in the Malanje District and Lunda Region, belong to those episodes. The Pliocene - Pleistocene limit is well shown in Angola by coastal upllft, formation of a southern dune sand desert, the deposition of surficial sedimentary cover on the plateaus and the fust Kalahari saods reworking episode.
