The kinematics of the collision in Western Alps are investigated through five balanced cross sections of the whole external domain from the Oisans to the Mont Blanc massif. These cross sections were built using published data for the Jura and subalpine fold-and-thrust belts and new structural and field analysis for the External Crystalline...

In the Western Alps, the External Crystalline Massifs (ECM) are key places to investigate the kinematics and thermal structure of a collisional crustal wedge, as their paleo-brittle/ductile transition is now exhumed at the surface. New (U–Th–Sm)/He data on zircon and new Raman Spectroscopy on Carbonaceous Material (RSCM) data from the Aiguilles...

International audience

Le but de cette contribution est de documenter et comprendre à la foisla cinématique des déformations collisionelles à l'échelle des Alpes externesoccidentales et le rôle de la structure de la marge européenne danscette structuration orogénique.Dans un premier temps, nous présentons des données nouvelles, structurales,microstructurales et...
