Structues associated to shale tectonic such as turtles, weldings and isoleted subbasins are revealed by the new interpretation of the region. This tectonic setting implies the presence of a detachment level along which these structures were developed during the Cenozoic. At least two phases of deformation are interpreted for the region: lateral expulsion of shale due to differential loading and a later shale upwelling related to inversion episodes. The understanding of the evolution of these new structural elements allows to postulate new migation paths which are favourable for hydrocarbon trapping and accumulation along the region.
