Model of evolution for the Culminating Range during the Mesozoic-Cenozoic evolution. (A) First stages from Jurassic to Neocomian, initial weak halokinesis, hypothetically at the vertical of inherited rifting normal faults. (B) Major halokinetic event in the Aptian-Albian, development of megaflaps in Kef N’Hal and GP, probable emplacement of salt canopies at least in the GP, overturning the older Mesozoic serie. An extensional activity is suggested. (C) Paleogene stage of compression, eroding partially, wiping out the canopies and welds formations. (D) Miocene stage of compression, during the main Tell phase, with the emplacement on top of the Ouarsenis massif of the external nappes with the maximum horizontal displacements.
