Abstract

Three sections from the Jebel Ben Younes reference outcrops are wisely sampled. Gathered macrofossils (ammonites, echinoderms, brachiopods) and calpionellid associations allow us to propose a first biozonation and update the age of the Sidi Khalif Formation (= Fm) in the Gafsa basin. A Lower-Middle Berriasian age is assigned to this lithostratigraphic unit. It is topped by a major discontinuity from which the Barremian Sidi Aïch Fm unconformably rests on. This hiatus is interpreted as the result of differential bottom topography structured under the synsedimentary control of the Southward-bordering Gafsa fault.
