“…Since then, the age of the Aptian series and the deposition environment of the Aptian-Albian successions have been refined by local works (M'Rabet et al, 1979;Ben Youssef et al, 1985a;Ben Youssef and Peybernes, 1986;Chaabani et al, 1992;Abdallah and Memmi, 1994;Abdallah et al, 1995;Hfaiedh et al, 2013;Godet et al 2014;Ben Ali et al, 2018). Meanwhile, the Mesozoic tectonic evolution of the basin has been studied by Abbes and Tlig (1991), Louhaichi and Tlig (1993), Hlaiem (1999), , Lazzez et al (2008) and Amamria et al (2021). These authors gave evidences of diapiric movements in the Jurassic-Early Cretaceous, significant Albian tectonic movements, and a major unconformity of Coniacian age.…”
