Subsurface Basin Framwork and Tectonic Salt Implications for the Upper Cretaceous Depositional Systems in Central Tunisia

P247 SUBSURFACE BASIN FRAMWORK AND SALT TECTONIC IMPLICATIONS FOR THE UPPER CRETACEOUS DEPOSITIONAL SYSTEMS IN CENTRAL TUNISIA ABSTRACT 1 Upper Cretaceous deposits in central Tunisia blocks had been studied using sequence stratigraphy seismic tectonics seismic mapping and the associated outcrop controls. The subsurface structure is marked by the existence of three main basin zones: Gafsa to the south Souinia-Majoura to the northeast and Madjel Bel Abbès to the southwest. Distribution of the basin depocenters and upthrowen are bounded by the N120 Gafsa and Majoura and N180 Sidi Ali Ben Aoun wrench salt-intruded tectonic corridors and subdivided by the associated N60
