Resumen:
A kinematic model is developed in order to explain basementinvolved backthrusts systems associated to uplifted basement blocks. In several places of the MalargOe fold and thrust belt there are some structures that show features, as tilted long limbs of folds and widely spaced backthrusts, that cannot be explained by classical models. In our model, the backthrusts and their hangingwall blocks are rotated due to shearing in the underlying basement rocks; this shearing take place when the displacement of the uplifted block towards the foreland is obstructed.
