Abstract

Late Cenozoic alluvial fans are well represented in western Iberia, marking the end of the sedimentary filling in many Cenozoic basins. The last alluvial episode is associated with the beginning of the exorheism, coeval with a hot and humid climate. They are mainly controlled by tectonics, involving thrusts and strike-slip faults with vertical offsets of a few hundred of meters. This tectonic reactivation rejuvenates the relief in the Leonese Mountains, and in the Estrela, Gata and Guadalupe Sierras. Given its age (Tortonian to Gelasian) and kinematics, they may be related to some kind of “Betics” rearrangement, but it is noticeable that they are absent in areas closest to the Betic foreland, as the Iberian Chain, where extensional tectonics predominates.
