oa Neogene Structural Evolution of the Southern Zone Bibans Chain (Algeria)

The area under study is located in the external zones of the Maghreb ides fold belt. This represents the southern section of the Alpine origin. It is bounded from the North by the Bibans chain, which constitutes the “para autochthonous” formations, that consists of Mesozoic limestones-marls series. From the South by the Meso-Cenozoic “foreland” shaley limestones. The whole area is unconformably overlaid by a sandy-shales miocene facies.
