• Resumen

  • A longitudinal WNW-ESE cross-section through the Graus-Tremp basin (southern Pyrenees) shows the geometry of several N-S structures contemporary with the eocene marine sediments. The main anticlines (Boltaha, Mediano and the southern prolongation of Turbôn) show a regional detachment level at the Triassic marls and evaporites. Some of them are associated with west-verging thrusts. A minor thrust-and -fold system (Arro-Los Molinos) involve the upper turbiditic systems. The relationships of structures with the syn-tectonic sedimentation allows to decipher the kinematics of the structures within the basin.
