• Resumen

  • Insitu data on the orientation of tectonic stress in northern Iberia are scarce. Breakout analysis performed on oriented caliper logs coming from hydrocarbon exploration wells has provided new data oh the orientation of tectonic stress in NE Iberia: southern Pyrenees, Ebro basin and N W Valencia Trough, that show a rather consistent NNE to ENE direction of maximun horizontal stress which differs significantly from the NW western European mean orientation. The area of study includes part of the old boundary between the African and Eurasian plates. It is concluded that NE-lberia is under NNE to ENE horizontal compression
