The detailed geological mapping supported by micropaleontological, tectonic and structural data of Souk Ahras region (North–East of Algeria) made it possible to define the main structural units of the external domain of the Maghrebides belt in the North–East of Algeria. The study area shows a block structure illustrating an allochthonous domain (Numidian unit, the northern Tellian unit and the southern Tellian) thrusting a folded para-autochthonous domain (the scaly unit of the Sellaoua type and the Dj. Graout unit). The current structure is edified into three phases at least: post Langhian phase, Tortonian phase and Pliocene phase.
