Atlantic-Type Passive Margin Structural Style of the Cretaceous Basin in Northern Tunisia: Paleoslope Reconstruction and Regional Tectonics

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