Collisional orogens are classically described as the result of continental accretion of proximal margins. This accretion leads to the creation of relief and to the important export of erosion products in the directly adjacent foreland basins. In this geodynamic scheme, only the least deformed pre-orogenic domains are considered. However, a growing number of geological field evidences indicate the preservation or even the reuse of structures inherited from the rifting phase preceding convergence and collision within orogens. By conducting a geo-thermochronometric study of the easternmost, inverted hyperextended Aptian-Cenomanian rift system (Agly massif, North Pyrenean Zone) and the adjacent early retroforeland (Rennes-les-Bains syncline, Aq...
