This thesis presents the results of a multidisciplinary study of sediments, with an emphasis on geochemistry, with the following objectives : 1) improve our understanding of geochemical processes occurring as a result of erosion, transport and deposition in two rift b asin in their early stage of development; 2) reconstruct environments in these two regions of the rift during the Late Pleistocene and Holocene and 3) define sedimentary and geochemical criteria to allow us to discriminate tectonic setting and climate change in nascent and early stage rift basins. The two basins chosen to represent early stagerift development were 1) the Makgadikgadi-Okavango-Zambesi basin located in NW Botswana and 2) the Mpulungu Basin, located at the south-...
