“…Azaïez et al (2007) attributed to the Austrian phase the Late Aptian tectonic unconformity that they observed in both field and seismic studies. Rigane et al (2010) observed two tectonic unconformities in the tectonic evolution of the Jebel El Hamra tilted blocs, which they dated as Aptian-Albian in age.…”

a b s t r a c tThe Jeffara escarpment spans 400 km from southeastern Tunisia to sorthwestern Libya, and marks the northern edge of the Berkine-Ghadames Basin. Its horseshoe shape provides a good 3D control of regional-scale depositional architecture. Historically, the political border between Tunisia and Libya hindered the integration of studies over its entirety, which led to the establishment of separate litho-biostratigraphic frameworks. Field-work undertaken on both sides of the border has allowed the unification of lithostratigraphic schemes developed in both countries. Published stratigraphic ages of the different formations and members are compared and integrated in order to propose a unified bio-lithostratigraphic framework. The correlation of serial sections along the Jeffara escarpment shows that two major tectonic unconformities divide the Early Cretaceous sedimentary pattern. The first one is dated as Late Aptian and is commonly associated with the European ''Austrian" tectonic phase. The second, which has previously not been recognized as a regional significant surface in Libya, occurs during the Middle Albian and marks moreover the transition from a siliciclastic to a carbonate-dominated sedimentation regime. These two important regional unconformities form the lower and upper boundaries of the Kiklah-Aïn el Guettar Formations, and can be associated with intra-plate deformation linked with the opening of the central segment of the South Atlantic and the Equatorial Atlantic oceans.

“…1B). Stratigraphic, sedimentologic and tectonic studies in this area have been undertaken since the beginning of the last century, and some of these studies have discussed the evolution of the sedimentary basins and the genesis of the ranges and associated structures (e.g., Pervinquière, 1903;Castany, 1954;Burollet, 1956;M'Rabet et al, 1979;Bismuth et al, 1981;Gargouri-Razgallah, 1983;Masse, 1984;Boltenhagen, 1985;Zargouni, 1985;Ouali et al, 1987;Abdallah 1989;Zouari et al, 1990Zouari et al, , 1999Boukadi, 1994;Negra, 1994;Abdallah et al, 1995Abdallah et al, , 2000Rabhi, 1999;Bédir et al, 2001; Bouaziz et al, 2002;Chaabani and Razgallah, 2006;Azaïez et al, 2007;Lazzez et al, 2008;Zouaghi, 2008;Gallala et al, 2009;Lehmann et al, 2009;Heldt et al, 2010). Other studies have shown that the Cretaceous strata in the central Atlas Mountains of Tunisia are organized into units and sequences (e.g., Tlatli, 1980;Bismuth et al, 1981;M'Rabet, 1981;Masse, 1984;Boltenhagen, 1985;Abdallah, 1989;Ben Youssef et al, 1989;Neri et al, 1991;Abdallah et al, 1995Abdallah et al, , 2000Chaabani, 1995;Sa...…”

“…From tectonic point of view, Jebel Sidi is truncated by the Sidi Aich major accident (Zitouni 1997;Boukadi and Bedir 1996;Hlaiem 1999;Bé dir et al 2000;Zouaghi et al 2009;Gabtni 2006 ;Azaiez et al 2007;Tanfous 2007). This NE-SW trending fault is responsible of an abnormal contact between the mio-plio-quaternary and the lower Cretaceous series.…”

The present study exposes two cases of geophysics use in civil engineering. ISSN 2157-6092 2014 www.macrothink.org/jee 11 Case of Jebel Ressas (North-East of Tunisia) -To recognize and characterize the basement of a future cement factory at Jebel Ressas (North -East of Tunisia), 25 vertical electrical soundings are performed using the Schlumberger configuration. The qualitative and quantitative interpretations of the obtained data show that the prospected area is affected by normal faults generating collapses and a remarkable thickening of the clayey layers towards the north and the west. Since many earthquakes marked the Jebel Ressas sector, these faults may be active. Journal of Environment and EcologyCase of Sidi Aich (South -West of Tunisia) -In order to determinate the factors which damaged the Sidi Aich school (Gafsa gouvernerate, Tunisia) a geophysical study is undertaken . Six vertical electrical soundings are realized. These VES interpretation show that the prospected lithological formations are characterized by facies, thickness and depth variations and affected by two NE-SW faults. The maps established from the VLF data gave more precisions .They identify four faults directed NE-SW to NNE-SSW. The microgravimetric measures dont furnishe any indication about the underground geometry of the Sidi Aich school since the litholgical formations are characterized by similar densities.
