Abstract

In central Tunisia, Upper Cretaceous deposits including rudist-coral carbonates are generally transgressive upon Lower Cretaceous formations that mainly consist of siliciclastic deposits sometimes associated to neritic and to emergent carbonates [1]. A regional sequence boundary separates the Upper Aptian emergent series and the Upper Albian transgressive deposits. On the basis of the rudist-rich carbonates used as a “facies reference”, the identification of transgressive-regressive cycles within the Upper Cretaceous series has helped a lot to establish correlations at regional and global scales.
