Discussion sur l'âge et le cadre structural de la sédimentation néogène dans la zone des dômes en Tunisie septentrionale

Discussion about the age and the structural framework of the Neogene sedimentation within the "zone des dômes" in northern Tunisia. The sedimentation of the Neogene post-Tortonian in the dome zone of Northern Tunisia was carried in two kinds of basins corresponding to subsident syncline gutters born of the Tortonian folding and pull-apart basins associated to the dextral subequatorial strike-slips. The Neogene sediments contain a rearranged fauna of Cretaceous, Paleogene and Lower Miocene stages. This phenomenon indicates its post-tectonic character. The Neogene series are framed by two major unconformities which indicate its sedimentation in a compressif structural setting, characterizing the Northern Tunisian Atlas.
