Abstract
Iberia provides a natural laboratory for documentation of intraplate alpine deformation. Although present-day topography is the result of the latest tectonic events occurred during the Eocene and Lower Miocene, the former evolution of related structures is not well documented. Hirtherto, the late-Variscan term offered a vague and wide temporal window, where most of the tectonic processes not well understood were included. We present an analogue modelling study where the control and alpine evolution of structures postdating the Variscan orogeny, originated during the formation of the Cantabrian Orocline (Ibero-Armorican Arc, 310-295 Ma), is investigated. The models surface was analyzed through the particle image velocimetry method, which provides useful information about the evolution and kinematics of structures developed during deformation. The results show that the present-day configuration of topography is strongly controlled by the presence of faults formed during the final stages of the orocline development and were subsequently reactivated during the Alpine cycle. These structures are responsible for topographic uplift leading to the evolution of intraplate reliefs and associated basins during the Pyrenean shortening.
