Deutsch: Moncucco-Decke Français: Nappe du Moncucco Italiano: Falda del Moncucco English: Moncucco Nappe
The Moncucco Nappe (Western Lepontic) occupies the core of the Vanzone Antiform in the Valle d’Ossola. It consists of a crystalline basement intruded by a Permian granite and is interpreted as the equivalent of the Monte Leone Nappe in the hangingwall of the Simplon Fault. Similar to that nappe, the Moncucco Nappe contains a large ultramafic body at its top.
The Ötztal Nappe forms the main part of the Ötztal Nappe Complex. It consists mainly of polymetamorphic paragneisses with minor orthogneisses and amphibolites.

In the Brig area (upper Valais), the Rosswald Slice forms a large anticline together with the Roignais-Versoyen Slice. The Rosswald Slice is only present east of the Rhône-Simplon Fault and forms the normal, thrusting limb, extending further east at the border of the Lepontic units. It contains only the upper formation of the «Valaisan Flysch» (St-Christophe-Formation).
