Abstract

The crystalline (Variscan) part of Corsica represents a natural laboratory for quantitative studies of surface processes in high mountainous areas and for calibration of surface process models, since it provides fairly simple preconditions. In general, steep relief is found in places of strongest Neogene uplift, which is partly related to large-scale tilting. According to the evaluation of average slope angles, the relief in alkaline magmatic rocks is steeper than in the more common subalkaline granites. Mapping of relief parameters yielded two generations of paleorelief: an older paleosurface in the level of the summits and a younger, mid-elevated piedmont-type planation surface. Our data suggest that the summit surface started to form after Late Eocene to mid-Oligocene uplift during a decline of relief until late Early Miocene time. The piedmont paleosurface formed after an uplift pulse at ∼ 17 Ma during a stagnation period in Middle Miocene. Tilting to the SW, uplift and incision of this surface started between 11 and 10 Ma, succeeded by minor, roughly even uplift in the order of several 100 meters.
