In central Tunisia, the thickness of the Bahloul Formation varies generally between 20 to 40 m such as for example, respectively, at wadi Smara near Kalaat Senan and at wadi Bahloul near Maktar. The thickness is also of several tens metres at Koudiat el Azreg near Jerissa and at Tajerouine. In these sites where the thickness of the Bahloul Formation is dilated, in addition to five geochemical...

High-resolution stratigraphy of the Cenomanian–Turonian boundary interval at Pueblo (USA) and wadi Bahloul (Tunisia): stable isotope and bio-events correlation = Stratigraphie à haute résolution de la limite Cénomanien–Turonien sur les coupes de Pueblo (États-Unis) et de l'Oued Bahloul (Tunisie) : isotopes stables et corrélation des événements biologiques

Caron, Michèle ; Dall’Agnolo, Stephan ; Accarie, Hugues ; Barrera, Enriqueta ; Kauffman, Erle G. ; Amédro, Francis ; Robaszynski, Francis

In: Geobios, 2006, vol. 39, no. 2, p. 171-200

A high-resolution stratigraphy has been developed for the interval encompassing the Cenomanian–Turonian boundary (CTBI), by means of several lithological, biological and geochemical events. This work entails the study of two sections selected on the base of the completeness of their sedimentary record and their contrasting paleogeographical setting: (1) The Rock Canyon Anticline section...
