Résumé

The spatial and kinematic association between kink bands in rocks with variscan foliation and alpine thrusts in the Central Sys- tem basement, allow us to deduce that the former have a Cenozoic age, and not variscan or late-variscan. Systematically, the fold axes trend of the kinks is sub-parallel to the strike of the thrusts. Three key outcrops are studied: the Villares de Jadraque thrust, the Valdesotos thrust and the El Atazar back-thrust.
