The Mores Trough (Aragonese Branch of the Iberian Chain) is filled by rocks of Triassic age (Germanic facies) unconformably overlying folded and fractured Paleozoic materials. The trough is delimited by two major NW–SE faults, the Purroy normal fault to the northeast, locally inverted, and the Inogés reverse fault to the southwest. In addition, other structures of a similar direction to the faults, such as folds, thrusts and normal faults can be found within the basin. Geological cross-sections and the measurement and interpretation of bedding and fracture data have allowed to give an interpretation of the different structures found in both basin boundaries. A first extensional stage during the Triassic produced synsedimentary normal faults, as the Purroy fault, and mesoscale horst and graben structures. A second compressive stage of Cenozoic age led to the reactivation of faults with a reverse component and the formation of folds.
