| Summary: | sia shows events of increased flooding and aggradation of relatively coarse overbank deposits. Geo-morphic activity in river systems within this region correlate with aridification of the climate, but not with temperature. The late-Pleistocene to mid-Holocene synthetic profile of the Ghardimaou floodplain (mid-Medjerda river) indicates fluvial activity from 12.4 to 11.8, 6.6 to 6.0 and after 4.8 ka cal. BP. Exter-nal correlations imply global and regional causes of the late-Pleistocene to mid-Holocene climatic devel-opment such as North Atlantic deep-water formation, fluctuations in Saharan humidity and impacts of local Mediterranean weather phenomena. Palaeomagnetic records offer additional opportunities to inter-pret fluvial activity in river systems, especially for detecting chronological hiatuses in apparently homo-geneous sediment sequences. |
