Estructura y cinemática de la falla de Alpeñés (Cordillera Ibérica)

Abstract

The Alpenes anticline is a detachment fold of the Jurassic-Cretaceous cover, whose location and geometry is controlled by the Alpenes NNE-SSW-trending basement fault. This fault constituted the southwestern margin of the Aliaga basin (Iberian Chain) during the Cretaceous, with a normal movement slipping northwards and was re-activated during the Tertiary compression as a right-lateral strike-slipreverse fault The cumulative heave of the Alpehes fault in the detached mesozoic cover is about 400 m, the western block being uplifted with respect to the eastern block during the mesozoic extension and tertiary inversion.
