Examples of facies changes and variations (for location, see Fig. 2). a, b Rawilpass (593555/137131): complete transgressive sequence in the Early Turonian; black shales are overlain by phosphate-rich conglomerates and pelagic limestones with Fe–Mg oxides and phosphatic horizons indicating reduced sedimentation rates. c Les Audannes north (595987/133145): unsorted sedimentary breccia overlying the escarpment surfaces. d Les Audannes south (595829/131514): breccia composed of clasts of the Seewen Formation and matrix that probably originated after in situ brecciation of the Seewen Formation veneers sedimented on the palaeo-escarpment surface. e Les Audannes north (595829/131514): plane parallel lamination characterized by internal erosional surfaces in calcarenitic levels of the Amden Formation
