Plio-Pleistocene fluvio-lacustrine continental successions can provide unique insights into link transformations of terrestrial ecosystems with related landscapes in East Africa.

Abstract

Plio-Pleistocene fluvio-lacustrine continental successions can provide unique insights into link transformations of terrestrial ecosystems with related landscapes in East Africa. Continental deposits of the Dandiero Basin (Eritrean Rift margin) form a 450–500 m sedimentary succession recording paleoecological and landscape transformations that occurred at the Early-Middle Pleistocene transition in the northernmost sector of the African Rift Valley. The Dandiero Basin is bounded by two main, roughly NNW-SSE trending faults, which were superimposed on the N-S trending faults that delimited the basin at early stage of development. The basin-fill succession consists of alternating fluvial and lacustrine deposits. The quality of magnetostratigraphic data and its comparison with radiometric dating and vertebrate paleontology, constrains deposition between about 1.2 up to 0.75 Ma. Integrated sedimentological, paleopedological and isotopic data suggest that although sedimentation occurred under the dominant control of tectonics repeated shifts from fluvial to lacustrine deposition were also triggered by climate forcings.
