    LA MISE EN EVIDENCE D’UNE NAPPE DE CHARRIAGE EN STRUCTURE IMBRIQUEE : CAS DE LA NAPPE TELLIENNE D’OULED DRISS, SOUKAHRAS, ALGERIE
    (COURRIER DU SAVOIR, Université Mohamed Khider – Biskra, Algérie, 2016) Abdallah CHABBI; Abdelmadjid CHOUABBI; Asma CHERMITI; Mohamed BEN YOUSSEF; Tayeb KOUADRIA; Mohamed GHANMI
    La cartographie géologique et les déterminations micropaléontologiques des formations telliennes de la région d’Ouled Driss au Nord de Souk Ahras (Algérie orientale) selon deux profils SSE-NNO, perpendiculaire à la structure, entre Oued el Maaden et Dj. Madjen M’Cid, ont abouti à l’identification de quatre unites telliennes à matériel Paléocène -Eocène, en structure imbriquée. Ces unités surmontent le domaine para-autochtone Sellaoua au sud, et couvertes au nord par la nappe numidienne de Dj. Madjen – Dj. M’Cid.

    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.
