Sequential restoration of the Valdria fold pair (gg’ cross-section, Fig. 11c) interpreted as a Jurassic extensional growth fold that developed in the hanging wall of a NW dipping normal fault cutting subsalt basement. The fold pair was later reactivated during Pyrenean emplacement of the NCO and again during the Oligo-Miocene extension. During NCO emplacement, the nappe detached a block from the basement high (responsable of the overturning of the Valdria fold pair) which was transported along with the NCO.
