Résumé
A geomorphological map of an area of 66 500 km 2 in the southeastern part of Kenya has been prepared. In the littoral zone eight major terrace levels occurring between the present shore and approximately 160 m +MSL have been described. Analysis of radiometric datings and uplift rates of the coastal succession suggested that the formation of the terraces extends over the last 1.4 my of the Pleistocene. Soil development indicate a climatic change from humid to savannah conditions at approximately 800 ky BP. Three sedimentary levels occurring in the landward part of the coastal region have been linked with the three highest littoral terraces. In the interior region, the denudation of the vast plains east of the 38° 15’ meridian was correlated with the deposition of Plio-Pleistocene deposits in the Lamu embayment and the coast.
