Collisional Mountain Belts
The European Alps is one of the most studied mountain belt in the world. This mountain resulted from the collision between the South-Alpine and the European continents following the closure of the Alpine ocean. The collision started 40Ma ago. Large nappes of the South Alpine continent were thrusted on top of sediments of the European platform. During the collision these nappes were folded and eroded. The Mont Cervin (or Matterhorn) is a klippen of South Alpine continent standing above a flat ophiolite bearing suture zone.
