La Bretagne armoricaine (France) revisitée. Nouveaux regards sur l'évolution des formes dans un massif ancien classique (The French armorican Britanny revisited. New insights on the geomorphological evolution of a classical old massif)

Abstract

The Rennes school of geologists has recently addressed the significance of the present-day drainage networks by looking at the relief development on the Armorican Massif basement. It assumes that differential uplift is responsible for the morphological evolution of this structural unit during Quaternary times. By contrast the following paper recalls that the remnants of planation surfaces allow us to reconstruct a history which is not only controlled by the reactivation of inherited fault zones, and suggests that the geomorphological evolution of this massif cannot be restricted to a late rejuvenation of a multi- storeyed topography by trustai uplift.
