“…The examination of soft-sediment deformation in various localities from northern Tunisia during Cretaceous time reveals the basin's submarine paleoslope using slump folds data and the tectonics regimes using fault kinematic analysis. Furthermore, the correlation drawn in the study area clearly reflect considerable thickness variations of the Cretaceous series related to synsedimentary normal faults activity probably responsible for tilted blocks basin geometry [9,15,23,58,63,64,73,86].…”

In this locality, from east to west, the Cenomanian series clearly show a considerable westward thickening that was probably related to synsedimentary normal faulting activity.…”

“…During Cenomanian times, high sedimentation rate is perceived followed by facies homogeneity, coeval with decreasing of salt tectonic activity in comparison with the Aptian-Albian period [61]. The thickness variations of the Cenomanian deposits are well correlated to normal faults activity [9,92]. Using the fault kinematic analysis, a pure extensional tectonic regime with NW-trending extension is proposed.…”

The purpose of this paper is to characterize the configuration of northern Tunisia's basin during the Cretaceous on the basis of abundant slump folds and frequent synsedimentary faults. The slump folds are studied to determine the slumps transport vergence on the synsedimentary submarine paleoslope. The local and regional stress field is used to characterize the syn-sedimentary deformation. During Valanginian-Aptian times, the basin is characterized by southward submarine slope. From Albian to Santonian times, the slump folds analysis provides a NNW-to NW-ward sloping topography. The fault kinematic analysis reveals a regional NW-to NNW-trending Cretaceous tectonic extension. Locally, a NE-to N-trending extension is characterized. A perturbation of paleoslope orientation is locally observed probably related to salt tectonics hyperactive during Aptian-Albian. The constructed regional cross-section shows a tilted block geometry governed by major basement faults associated to other intra-basin growth faults. The basin shows a ±5° seaward facing submarine paleoslope. In addition, some structures are probably dominated by raft tectonics.2 All these features are fairly consistent with the conclusion that the basin is very similar to the present-day Atlantic-type passive margins.
