The “Aptian Crisis” of the South-Tethyan margin: New tectonic data in Tunisia

“…All authors agree that the Early Cretaceous sedimentary succession of central Tunisia corresponds to an unstable platform with clastic deposits in the South and open marine facies in the North (Marie et al, 1984;Dlala, 1999). At the end of the Early Cretaceous, positive vertical movements are followed by erosion, in particular along the North-South Axis (NSA) where the Upper Albian in many places lies unconformably on the underlying succession (Burollet, 1956;Biely et al, 1973).…”

“…Very often, the transition in central Tunisia takes place via platform carbonate facies. However, the very irregular subsidence leads locally -and sometimes abruptly -to large variations in thickness and facies (Marie et al, 1984;Rigane et al, 2005). Lastly, in Eastern Tunisia, both on land and offshore, the Cretaceous rocks are well-known in drill-holes, which encounter many volcanic intercalations: dykes, sills, tuffs, ashes and rare lava flows (Burollet, 1956;Bajanik, 1971;Ellouz, 1984;Patriat et al, 2003).…”

Analysis of Cretaceous (Aptian) strata in central Tunisia, using 2D seismic data and well logs

“…16) with some reef buildings (M'Rabet et al, 1979;Tlatli, 1980;M'Rabet, 1981;Masse, 1984;Marie et al, 1984;Heldt et al, 2010).…”

Seismic sequence stratigraphy and platform to basin reservoir structuring of Lower Cretaceous deposits in the Sidi Aïch-Majoura region (Central Tunisia)

“…Most of them are dated by framing. Several authors had been interested in the definition and the dating of the Lower Cretaceous deposits (Castany, 1951;Burollet, 1956;Burollet et al, 1983;Masse, 1984;Marie et al, 1984;Memmi, 1989;Guirand, 1968;Coiffait, 1974;Fournié and Pacaud, 1973;M'Rabet, 1981M'Rabet, , 1984M'Rabet et al, 1979M'Rabet et al, , 1995Zghal, 1994;Chekhma, 1996;Chekhma et al, 1990;Gorin et al, 1996;Ben Youssef, 1999;Schnyder et al, 2005).…”
