English: Gotthard Nappe
The Gotthard Nappe, extending from Brig in Valais to Ilanz in Graubünden, is an Upper Helvetic tectonic unit with a crystalline core (former “Gotthard Massif”) consisting of pre-Caledonian and pre-Variscan para- and orthogneisses, as well as Late Variscan granitic intrusions. The sedimentary cover of this nappe varies from place to place: “Urseren-Garvera Zone” (including "Goms Massif") at the northern border of the nappe, “Termen Zone” and “Nufenen Zone” at the southern border between Brig and Airolo.
