Découverte de l'Éocène continental autour de l'archipel de Kasserine, aux Jebels Rhéouis, Boudinar et Chamsi en Tunisie centro-méridionale : nouvelles implications paléogéographiques

The Rhéouis and Boudinar Eocene outcrops located along the Tunisian ‘north–south axis’ show continental deposits similar to those already described in the west-central and meridional Atlas in the Jebel Chaambi and Chebket Bouloufa. The field investigations of these levels conduct to the discovery of Bulimes' terrestrial Gastropods known in the Mediterranean domain. The presence of palygorskite in the clay minerals confirms the emerged tendency of these deposits. The continental palaeogeography might have been induced by the Triassic halokinetic movements along the Atlasic anticlines.
