Deutsch: Säntis-Decke Français: Nappe du Säntis Italiano: Falda del Säntis English: Säntis Nappe
The Säntis Nappe is an Upper Helvetic tectonic nappe of the Eastern Swiss Alps, extending from the Linth Valley in the west to the Rhine Valley in the east (including the Fläscher Berg east of Sargans). It overlies the Glarus Nappe Complex north of the Walensee and Seeztal, forming a broad synform, in the core of which are preserved klippen consisting of Upper Helvetic mélanges, as well as Lower and Middle Penninic units. The Säntis Nappe is composed of Cretaceous and rare Paleogene sediments. Its internal structure is characterized by fold trains and fold-parallel thrust faults, with an important N–S oriented fault between Sax and Appenzell (Sax-Schwende Fault) that can be shown to have been active during the nappe internal deformation.
Deutsch: Grosina-Decke Français: Nappe de la Grosina Italiano: Falda della Grosina English: Grosina Nappe
The Grosina Nappe forms a series of tectonic klippes on the southwestern parts of the Campo Nappe along a distinct mylonitic zone associated with top-NW to top-N senses of shear of Cretaceous age that possibly reworked a Jurassic décollement zone. The amphibolite-facies Variscan basement of the Grosina Nappe is in parts similar to that of the underlying Campo Nappe. However, the basement of the Grosina Nappe differs in that orthogneisses are much more frequent, and, additionally, in that there is often a pervasive greenschist-facies metamorphic overprint of the older high-grade fabrics. The root zone of the Grosina Nappe most probably occurs at the southern margin of the Campo Nappe Complex and in the immediate footwall of the tectonically higher Tonale Nappe.
Deutsch: Puschlin-Zone Français: Zone de Puschlin Italiano: Zona di Puschlin English: Puschlin Zone
Within the Landeck Quarzphyllites, the «Puschlin Zone» encompasses very small lenses of Permo-Carboniferous and Early Triassic slivers (metaconglomerates, metasandstones and phyllites, as well as cataclasites).
Deutsch: Mont-Blanc-Massiv Français: Massif du Mont Blanc Italiano: Massiccio del Monte Bianco English: Mont Blanc Massif
The Mont Blanc Massif, divided into an external and an internal part by a major fault, is a Lower Helvetic External Massif of the French and Western Swiss Alps. It is constituted of a pre-Variscan polycyclic basement (Precambrian to Early Cretaceous) intruded by Variscan granites and of a Mesozoic–Cenozoic sedimentary cover. The Mont Blanc Massif is separated from the Belledonne Massif by the axial depression of the Val Montjoie and from the Aiguilles Rouges Massif by a thin band of Mesozoic sediments often («Chamonix Syncline»).

Deutsch: Drusberg-Decke Français: Nappe du Drusberg Italiano: Falda del Drusberg English: Drusberg Nappe
Within the Upper Helvetic, the Drusberg Nappe, together with the Axen Nappe, represents the continuation of the Wildhorn Nappe Complex east of the Kander Valley. The Drusberg Nappe consists only of Cretaceous to Paleogene sediments, locally with slices of Late Jurassic limestone (Quinten Formation) at its base.
Deutsch: Mont-Mary-Decke Français: Nappe du Mont Mary Italiano: Falda del Mont Mary English: Mont Mary Nappe
The Mont Mary Nappe is a Salassic tectonic unit constituted by two crystalline basement units: a Lower Unit mainly comprising pre-Alpine amphibolite-facies paragneisses with minor amphibolites and orthogneisses and an Upper Unit comprising pre-Alpine amphibolite- to granulite-facies paragneisses with mafic and carbonate rocks.
