Relief rejuvenation in response to intraplate neotectonics in the Betics foreland (southern Spain)

deformation. In these long-lived areas, characterized by previous mechanical discontinuities, rejuvenation may be strongly controlled by fault reactivation, as these structures must play a significant role on strain localization and strain partitioning. We analyze these topics in the Betics foreland, in the so-called forebulge. It consists of a flexural WSW-ENE relief, related to the orogenic load of the Betics, an alpine chain mainly stacked during the Miocene. The southern limit of the forebulge coincides with a sharp topographic escarpment separating the foreland and the Guadalquivir river basin (i.e. the Betics foreland basin). We have combined structural and geomorphic tools, the latter including both qualitative and quantitative techniques (geomorphic indexes). Our analysis are focused on tributaries drainage networks located on the Guadalquivir river right bank, covering Introduction Relief rejuvenation in response to intraplate neotectonics in the Betics foreland (southern Spain)
