Deep Water Status in Southwestern Tunisia

“…The interpolation of this level between different lines allows us to achieve isochrone map of Segui region [22]. Then, based on the time-depth curve, we generate the depth map, linking equal depth zone.…”

Seismic Reflection Contribution to the Study of the Jerid Complexe Terminal Aquifer (Tunisia)"

“…The anticlinal structures of Draa Jerid and Sidi Bouhlel, situated between El Gharsa Chott and Jerid Chott (Fig.2), constitute the western extent of the Chotts fold belt (Fakraoui, 1990;Zouaghi et al, 2011), which corresponds to the most southern structures of the Atlassic domain (Abdeljaoued,1983;Rabia ,1984 ;Zargouni, 1985;Abbes & Zargouni, 1986;Fakraoui, 1990;Ben Ayed, 1993;Boukadi, 1994;Zouari, 1995;Bouaziz, 1995;Bédir, 1995;Hlaiem, 1999;Zouaghi et al, 2005;Lazzez et al,2008).…”

Tunisian Transtensive Basins in Tethyan Geodynamic Context and Their Post-Tortonian Inversion

“…(2) The Southern boundary also corresponds to a faulted domain, known as the Gafsa-Negrine-Tozeur (GNTC) (Zargouni, 1986;Zouaghi et al, 2005). The GNTC interrupts the extension of the NSC towards the south in the Gabès area, and corresponds to the Southern Saharan Atlas limited by the Gafsa fault in the North and the Negrine-Tozeur fault in the South Boukadi, 1998;Zouari, 1999).…”

“…This Northern boundary cuts across and limits the NSC in the North, so this feature is bounded at both extremities. Finally, within the TB corresponds to a mosaic of second-order blocks (Gourmelen et al, 2000;Zouaghi et al, 2005;Rigane and Gourmelen, submitted). In this domain, we observe widely spaced SW-NE anticlinal folds separated by vast plains very often occupied by sebkhas.…”

“…In agreement with the present study, other authors (Brahim and Mercier, 2007) have shown that these discordances are actually located on the flanks of diapiric domes and result from a slow and progressive diapirism. Zouaghi et al (2005) also propose a compressive phase during the Late Cretaceous and even at the end of the Aptian (Ben Ayed, 1986;Rabhi and Ben Ayed, 1990;Ben Ayed et al, 1997;Bouaziz et al, 2002). In these two latter cases, we consider that the discordances observed by these authors are either of the same type as previously described (on diapir flanks) or relate to disharmonic structures within the Miocene and Quaternary folds or are located on top of drape fold zones (Gourmelen et al, 2000;Rigane et al, 2010).…”
