(NLD) Palaeogeogr., Palaeoclimatol., Palaeoecol. Sedimentologic and paleotectonic evolution of carbonate platforms on a segmented continental margin example of the African Tethyan margin during Turonian and Early Senonian times. During Turonian and Early Senonian times, there were extensive shallow-water carbonate platforms on the Northern margin of the African craton (Eastern Algeria, Central Tunisia and adjacent offshore areas), at the edge of the Tethys ocean. The development of these carbonate platforms (Mid-Turonian to Late Coniacian)was especially controlled by the segmentation of the African (Saharan)margin by extensional fault systems, as evidenced by block-faulting, volcanic activity and halokinetic movements. From the Mid-Turonian to Early Coniacian times, the carbonate platforms underwent an incipient drowning, indicated both by their sedimentologic evolution (rimmed-shelves to carbonate ramps)and the landward shift of facies belts.
