“…Maïder basins to the southeast in the Algerian Sahara (Wendt et al 1984;Wendt, 1985;Abbache et al 2019). In this area, the top of the Cheffar el Ahmar Formation is a distal ramp sedimentation with green shales interbedded with nodular limestones followed by 'griotte' limestones interbedded with red shales.…”

“…At the beginning of Frasnian time, the Tafilalt Platform emerged before being flooded again (Michard et al 2008) and the Maïder Platform partly emerged (Wendt, 1985). On the northwestern margin of the Algerian Sahara, a tectono-eustatic control is reflected in differences in lateral facies and thickness in sediments accumulated on a distal platform and in basins (Abbache et al 2019). The Late Devonian period marked the most important phase of epeirorgenic movements in the Saoura, leading to an important subsidence (Benhamou et al 2004).…”
