    The External Domain of Maghrebides Belt on the North–East of Algeria, Souk Ahras Segment: Definition of Structural Units, Block Structure and Timing of Thrusts Setting
    (2019) Abdallah CHABBI; Asma Chermiti; Abdelmadjid Chouabbi; Mohamed Benyoussef
    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.

    Stratigraphy and Structural Style of the Maghrebides Belt Foreland: Souk Ahras Sellaoua Unit Case (External Domain, NE Algeria)
    (2022) Abdallah CHABBI; Asma Chermiti; Stéphane Brusset
    The Sellaoua Unit is part of the foreland of the Maghrebides belt in northeastern Algeria and develops in the footwall of Tellian and Numidian thrust sheets. Detailed geological mapping of Souk Ahras Sellaoua Unit (North–East of Algeria) supported by micro-paleontological and structural data allows us to reappraise the stratigraphy and the structural style of such area and characterize its relationship with the northern adjacent thrust sheets. Data were collected from sampling and observations along with four profiles for biostratigraphic study and five for structural constructions. The obtained results show that the Sellaoua Unit of the Souk Ahras area is made of carbonate marine formations ranging from Turonian to Paleocene uncomfortably overlain by detrital Miocene strata. Complex thrust systems have occurred during the Tertiary until the middle Miocene.
