“…This illustrates the influence of vertical movements of diapirs on paleobathymetry and sedimentation. This has been already described by Masse and Thieuloy (1979), Masse and Chikhi-Ouimer (1982), Mrabet (1984), Camoin et al (1990) and by Jaillard et al (2013) in neighbouring areas. The morphostructural analysis of the KNA section allows us to identify a drape-fold halokinetic sequence (hook sequence) located above the Triassic salt body of Debadib-BenGasser.…”

Facies and morphostructural enable the recognition of salt-sediment interaction close to the Triassic evaporites of the NE-SW elongated structures of the Kef-Tajerouine area, NW Tunisia. Unconformity-bound growth strata associated with passively rising salt diapirs defined as halokinetic sequences have been recognized within the Debadib-Ben Gasser Triassic salt body (El Kef-Tajerouine area), at the Triassic contact at Guern Halfaya, at J. Slata, and the South of J. Harraba. Salt tectonics was active during the period spanning from the late Albian in the salt province of NW of Tunisia. Facies analyses of Albian sediments revealed that the diapirism appears mainly in the deep facies of the Fahdene Formation. The halokinetic Albian sequences are formed owing to the variations in sediment-accumulation rate versus diapir-rise rate and roof thickness. The halokinetic sequences above and beside the Triassic salt bodies suggest passive diapirism at this time interval. Composite halokinetic sequences bounding unconformities correlate to periods of slower deposition (transgressive system tract).

“…The diversity maximum moved southward; in the early Maastrichtian it was situated in Sicily where there are rudist-coral and monospecific rudist-dominated biostromes (Cestari and Sirna, 1987;Camoin et al, 1988). From the Campanian to Maastrichtian, complex rudist-coral and monospecific rudist biostromes were widely distributed in Tunisia and Algeria, on the southern Tethyan margin (M'Rabet et al, 1986;Camoin et al, 1990).…”

“…The diapiric structures are numerous and can influence locally the sedimentary and structural evolution of the sedimentary cover. In the Khenchela region, diapiric movements allow the development of the santonian reefs [16,34]. In the "diapirs zone", these phenomena are important and are found interrupting the Upper Cretaceous and Tertiary formations [25,28,32,35,36].…”

The integration and processing of geological/depositional, geophysical and geochemical data in a geographic information system, contributed to the accurate determination of the spatial distribution and particularities of the Pb-Zn-Fe-Ba (Cu, Hg, F, Sr) mineralization of the Sétifien/Hodna region and the eastern Saharan Atlas. The treatment and analysis by application of the principle functionalities of the spatial module to these geoscientific data in terms of axes/trends shows the existence of a spatial correlation between mineralization and certain families of preferential lineaments/trends. The combination of gravimetric and aeromagnetic data reveals important tectonic lineaments mainly directed from N135° to N170° and N40° to N60°. The location of the mineralization near or along these tecto-lineaments and at the limits of sedimentary basins margins, reinforces the hypothesis of a strong relationship between these two geological phenomena. The ordinary kriging interpolation of Pb-Zn-Cu-Fe (%) concentrations, measured by direct measurements, shows a linear mineral zoning with directions similar to those recorded for the lineaments. These directions probably reflect deformation corridors that have controlled the emplacement of mineralized deposits and that may represent potential targets for mineral exploration.
