“…Finally, a distensive tectonic phase towards the end of Upper Aptian, known as the ''Aptian Crisis" (Soyer and Tricart, 1987), appears to have led to the breakup of the northern edge of the Saharan platform into distinct compartments (Bismuth et al, 1982;Martinez et al, 1991). The periodic recurrence of these blocks in tilted blocks has a major influence in determining the paleogeography of central Tunisia during the ''Middle Cretaceous".…”

“…The reactivation of major faults associated with these structural trends and the Triassic diapirism has resulted in a complex tectonic history. Most studies (Bismuth et al, 1982;Boltenhagen, 1985a,b;Soyer and Tricart, 1987;Martinez et al, 1991;Bouaziz et al, 2002;Feki et al, 2005a,b;Rigane et al, 2005) propose that the Saharan platform in Tunisia was compartmentalized by a distensive tectonic phase towards the end of the Aptian.…”

“…The Quaternary deposits are constituted of thin terraces and red soils and lay unconformably on the Neogene series, except in the Chérayaa uplift zone. In this zone, where the Neogene formations outcrop, the tectonic uplift is likely the result of three ancient normal faults inverted later, during the Tertiary, with a young displacement exceeding sometimes the older (Bismuth et al 1981;Chihi 1984;Kadri 1993;Zghal 1994). Groundwater in the Sbeïtla synclinal basin is hosted in three main reservoirs (Fig.…”

The scarcity of surface water resources in arid and semi-arid regions from North African countries contributes to the considerable increase of groundwater exploitation, which leads to the development of hydrogeological studies. However, due to the lack of hydrodynamic data in these regions, these studies focus more and more on the geochemical and environmental isotope techniques to insure a better understanding of the hydrodynamic functioning of subsurface systems. In this study, which interests an important unconfined aquifer in central Tunisia, tritium data and chloride mass balance (CMB) method were applied in order to (1) understand the mode of recharge of this aquifer and (2) obtain a reliable estimation of its recharge amount as well as (3) estimate its annual renewal rate. It has been demonstrated that the shallow groundwaters are classified into two groups according to their tritium contents. The first group includes wells located mainly downstream and highlights the significant role of the postnuclear lineal recharge through Wadis courses. The second group encloses wells located practically overall the rest of the basin and refers to relatively modern waters originated from areal recharge of present-day rainfall. Based on the CMB method, the recharge to this unconfined aquifer is estimated to 31.7 mm year -1 , which corresponds to 10.5% of the total rainfall. The annual renewal rate of groundwater, evaluated based on the tritium contents, is up to 16%.

“…The series leveling in the zone cover the Hauterivian-Cenomanian period with a hiatus of the lower and middle Albian which is materialized by a unconformity covering all central Tunisia [20]. In this field, the upper Albian series are unmatched on various terms of the Barremian-aptian series.…”

The study of the tectono-sedimentary evolution of the lower Cretaceous series realized in the southern on the tethysian margin in the Tunisian central-Southerner Atlas, shows that the architecture of this field is governed by a NW-SE compressive phase. This latter has reactivated the old faults to give birth to associated, distensive and compressive structures at the same time simultaneously. It is about a network of combined strike slip fault EW dextral and sinistral NS which divided the cover into four zones of deformation corresponding to the right dihedron of the strike slip fault system. In the compressive dihedron, the deformation develops essentially several folds and in the distensive dihedron, normal faults which delimit horsts and grabens.
