Abstract: | The current structure of the central Tunisian Atlas fossilizes the different tectonic events that have succeeded and that have structured this region. The Lower Cretaceous of this sector reflects, through variations of thickness and facies, the importance of the tectonic activity during this period. The tectonic study detailed in this sector has revealed the existence of structures from the kilometric scale down to the metric one related to a compressive regime that has dominated the studied zone at least from the Upper Hauterivian until the Lower Aptian. |
