“…were the cause of the first Triassic salt extrusion N40-50 and N 110-120 trends. This later shows a disposition of tilted blocks developing first in Upper Aptian [18,38]. The next major phase in the area was dated to the end of the Santonian time [32] marked by the transgressive cycle of Early Campanian marls bearing G. elevata, G.ventricosa, G. stuatiformis, on numerous substratums as observed on the Triassic sheet of W. Bou Kralfa (Fig.…”

“…The North-East Moghrebian passive margin was considered in a rifting regime during Aptian and Early Albian times [9,10,12,18,28,31,32,41,61]. Its inverted basins that were in compression regime began to form in the transition between Lower and Upper Senonian [ 15,32,40,61] and its paroxysmal event started in the Middle-Late Eocene episode.…”

In the northern part of Tunisia, close to Testour/Slouguia, new observations and updated biostratigraphy make it possible to highlight the relation between the Triassic saliferous mass and the surrounding Mesozoic beds (T. M.). Near the (T. M.) boundary, the formations observed consist dominantly of Triassic evaporites reworked in the Early and Late Albian deep-water sedimentary deposits. Throughout the studied area, Jurassic rocks are absent. We propose to interpret the Chitana-Ed Djebs structure originally emplaced as gravitational stretch masses in a passive margin in the same way as the salt bodies of widespread salt province in the Gulf of Mexico. A reconstructed schematic position of the Chitana-Ed Djebs salt body displays a scenario of setting of the salt mass on a submarine palaeo-slope. Moreover, the starting clues of the paroxysmal event of the Late Mesozoic tectonic inversion clearly fossilized through the discordance of the Middle Eocene-Early Lutetian limestone on the Albian series.

“…In Tunisia, several sedimentary-tectonic structures are contemporary and compatible with this compressive phase of the lower Cretaceous: in the area of Kef, along the synsedimentary faults of NS and EW direction, the series of Valanginian-Barremian show discordances, gaps, variations thicknesses and facies and the reduced lower Albian, rests directly on Barremian [15]. In the Hammamet Gulf, the sub-meridian accidents show a reverse strike slip fault movement at that time [13].…”

“…The seismic profile interpretation of Kasserine area highlights a NE-SW distension during the lower Cretaceous [12][13][14]. This extension is also signaled in the Kef area [15]. In the Tunisian South, some folds along EW Tebaga accident evoke strike slip fault movement of Aptian tectonics age [13] and in the Salt area the sedimentary sequence record this Austrian phase [16].…”

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.

“…During Cenomanian period, is a second extensional event that has continued in the study domain [3,14,[29][30][31][32][33][34][35]. The Late Cretaceous extensions affected the whole Northeastern African margin, originating NW-SE to NNW-SSE striking basins [3,14,36]. From the Cenomanian to the Early Maastrichtian times, was the same regional NE-SW extension.…”

Gravity data associated with surface geology in the Northern Tunisian Atlas offer better understand to the underlying structures in Teboursouk area and to highlight other deep or unknown structures in surface. The gravity study was based on qualitative and quantitative analysis including the construction of the gravity Bouguer anomaly, upward continuations, residual anomaly, and Horizontal gradient maxima maps. The main results display many positive and negative anomalies as the response of geological structures (J. Cheid Triassic structure, Khalled plain, El Aroussa plain). In addition, the horizontal gradient maxima integrated with geological and structural maps let the identification of major directions of gravimetric lineaments in the study area us NE-SW trending features at the boundaries of J. Cheid structure, NW-SE direction that limit Gaafour plain and Tabet Ech Cherif syncline, and N-S trending that bordered El Aroussa basin. Major results allowed the construction of a new structural map of the study zone.
