p.61: In western Switzerland, the Penninic domain occupies a large portion of the canton Valais south of the Rhône Valley and extends southward into adjacent Italy. A major thrust fault, known as the “Penninic Basal Thrust” or more generally “Penninic Front”, limits this domain to the west. Along the Rhône Valley between Saxon and Visp, the northern border is represented by the Rhône-Simplon Fault Zone, except between Sion and Sierre, where the Penninic Basal Thrust is preserved in some places. To the southeast, the Penninic is bounded by the thrust of the Sesia Nappe, which is the hangingwall of the Piemonte-Liguria Ocean subduction zone. In western Switzerland, the Penninic domain is overlain by the klippen of the Salassic Dent Blanche and Mont Mary nappes.
