- W2080235580 abstract "Abstract The history of Continental Sediments in Africa dates back to the end of the Precambrian Era when the development of the Super Continent of Gondwana was completed by the Pan African event. Africa was at the centre of the Super Continent. The African chains were up-lifted and eroded during the late Precambrian and early Cambrian period. Subsidence and the filling-up of the intermountain basins commenced in different parts of the continent and sedimentation was strongly influenced by climatic variations. Continental sediments are very extensive in Africa but knowledge of African sediments has been very general and often imprecise. This is due to the difficulties involved in the investigation of continental sediments that are usually poorly fossiliferous and highly oxidized. Their characteristic red colouration often obscure important aspects that could facilitate more detailed study. This article provides a general review of the major supergroups or groups of continental sediments in Africa. It highlights important achievements of various national and international teams participating in the Geological society of Africa's Working Group on African Continental Sediments (IGCP Projects 127 and 210) Their achievements include the recognition of several marine horizons within sequences that were previously considered as entirely continental in origin (e.g., Nubia Strata in NE Africa and Continental Terminal in coastal West Africa). More detailed stratigraphic subdivisions of continental beds have been facilitated by the presence of trace fossils, fossil wood, pollens and spores. The economic importance of African continental sediments are highlighted." @default.
