The Proterozoic is the last geochronologic eon of the Precambrian, starting with the Siderian period (at the transition from the Archean eon) and ending with the Ediacaran period (at the transition to the Phanerozoic eon). It is subdivided in three eras (Paleo-, Meso- and Neoproterozoic).

Deutsch: Berisal-Decke Français: Nappe de Berisal Italiano: Falda di Berisal English: Berisal Nappe
The Berisal Nappe is a Middle Penninic tectonic unit occupying the core of the large synformal Berisal Backfold. It consists of a polycyclic basement with numerous pre-Alpine relics. It is thus lithologically similar to the Upper Stalden Nappe and interpreted as the continuation of this unit to the east, in the footwall of the Rhône-Simplon Fault.

Deutsch: Sublage-Decke Français: Nappe du Sublage Italiano: Falda del Sublage English: Sublage Nappe
The Sublage Nappe is an Upper Helvetic tectonic nappe in the Western Swiss Alps. It is the highest unit of the Wildhorn Nappe Complex and forms the main body of the complex. To the southwest it overlies the Mont Gond Nappe, whereas it overlies the thin Jägerchrüz Nappe north of Sierre and the Gellihorn Nappe further northeast.
Deutsch: Belledonne-Massiv Français: Massif de Belledonne Italiano: Massiccio di Belledonne English: Belledonne Massif
The Belledonne Massif is a Lower Helvetic External Massif of the French Alps. It is constituted of a pre-Variscan polycyclic basement (Precambrian to Early Cretaceous) intruded by Variscan granites and of a Mesozoic sedimentary cover. The Belledonne Massif is separated from the Aiguilles Rouges and Mont Blanc massifs by the axial depression of the Val Montjoie.
Deutsch: Bad-Ragaz-Decke Français: Nappe de Bad Ragaz Italiano: Falda di Bad Ragaz English: Bad Ragaz Nappe
The Bad Ragaz Nappe is a Lower Helvetic tectonic nappe emplaced in an early phase onto the future Helvetic domain, subsequently truncated by the Glarus Thrust and simultaneously cut by out-of-sequence thrusts. It is composed mainly of Late Cretaceous to Paleogene sediments of South Helvetic affinity, cropping out in the area between Linthal and Sargans.
Deutsch: Landwasser-Synklinal Français: Synclinal de la Landwasser Italiano: Sinclinale della Landwasser English: Landwasser Syncline
The SW–NE striking Landwasser Syncline comprises the Triassic cover of the Silvretta Nappe at its western edge. It formed during top-NW thrusting in the Cretaceous, and then was overprinted by normal faulting still in the latest Cretaceous. This was followed by top-N thrusting of the entire Silvretta Nappe over the Penninic units during Cenozoic times.

The SW–NE striking Ducan Syncline comprises the Triassic cover of the Silvretta Nappe at its western edge. It formed during top-NW thrusting in the Cretaceous, and then was overprinted by normal faulting still in the latest Cretaceous.

Deutsch: Piz-Lizun-Einheit Français: Unité du Piz Lizun Italiano: Unità del Piz Lizun English: Piz Lizun Unit
Within the Upper Penninic Malenco-Forno-Lizun Nappe, the Lizun unit is situated northwest of the Engadine Fault and is sinistrally offset from the Forno unit. It exposes rocks of oceanic origin similar to those of this latter unit (i.e. metabasalts and metagabbros of oceanic origin covered by metasedimentary rocks of Jurassic to Early Cretaceous age).
