Geochronological approach of the Quaternary deposits of the Morsott profiles, along with the profiles of Blirth in Morocco and Sbeitla in Tunisia. The correlation made between already established profiles, in Tunisia and Morocco, indicates that quaternary deposits are variable in time, alternating wet and sub-arid phases, some parts are absent because of the alteration, the basic level is met in Algeria and Tunisia, in Morocco the profiles made of Holocene sediments did not reach the Pleistocene base. The absolute ages range from the upper Pleistocene at the base to the Holocene at the top. Mean sea level variation curves show the transition from a late glacial period to a post-glacial period. The sea level elevation induces the raising of the basal levels of the various wadis (Lambeck et al., 2014).
