 The Valencia Basin lies along offshore Southern Spain and it is bounded to the north and the south by the Betic Cordillera and in its westernmost part by the Pyrenees. The present structure of the Valencia Trough is the result of the extensional phases, accompanied by widespread volcanic activity with calc-alkaline and alkaline products, which involved the area from the Oligocene-Miocene transition to the early Middle Miocene. The upper crust in the Valencia Trough is strongly asymmetric, with the Iberian slope, located near the NW side of the trough, showing a thick skinned extensional structure characterized by NE-SW striking normal faults mostly dipping towards NW. The major faults, however, along the NW boundary in the Catalan area, dip to the SE and involve partial or total reactivation of Paleogene thrusts faults which, in turn, reactivate Mesozoic extensional faults. The Balearic slope is characterized by several basement highs interpreted as fault-propagation or fault-bend folds associated with SE-dipping thrust faults, bounded by both normal and thrust faults. During the Middle and Late Miocene, the tectonic inversion of former extensional structures into a contractional regime caused the propagation towards the NW of the Balearic fold-and-thrust belt. The Valencia Basin lies along offshore Southern Spain and it is bounded to the north and the south by the Betic Cordillera and in its westernmost part by the Pyrenees.
