p.63: Between Visp and the Simplonpass, two graphitic schist and paragneiss slices are attributed to the Zone Houillère by analogy with the rocks of this unit further west. The Visperterminen Slice occupies the core of a fold within the Sion-Courmayeur Nappe. The Lower Stalden Slice is overlain by the Upper Stalden Nappe and separated from the Sion-Courmayeur Nappe by the southern branch of the Rhône-Simplon Fault.
