Shaping of intraplate mountain patterns: The Cantabrian orocline legacy in Alpine Iberia

The present-day topography in Iberia is related to geodynamic processes dealing with lithospheric-scale deformation. However, little attention has been paid to the role of inherited crustal- or lithospheric-scale structures involved in the recent observed large-scale topographic patterns. Whereas th...
