The “Oberer Gneiszug” is a narrow band of Sesvenna basement that rims the southeastern part of the Lower Engadine Window between Scuol and Nauders.

The Marzio Fault separates the WSW–ENE trending Arbostora Anticline (southern part of the Varesotto Imbricates) from a complex syncline of imbricated Mesozoic sediments.

Deutsch: Avers-Decke
Français: Nappe de l'Avers
Italiano: Falda dell'Avers
English: Avers Nappe

The Avers Nappe is an Upper Penninic tectonic unit of eastern Switzerland made up of shaly-calcareous-sandy marine sediments and ophiolitic rocks originating from the Piemonte-Liguria Ocean. This nappe represents an accretionary wedge at the base of an upper plate consisting of the other Upper Penninic and overlying Austroalpine nappes. This wedge directly overlies the Mesozoic cover of the Middle Penninic Suretta Nappe and probably formed in the Early Paleocene. The basal thrust of the Avers Nappe was deformed congruently with the Suretta Nappe, and both units were later back-folded together in the upper limb of the huge Niemet-Beverin Backfold. A backthrust that formed during this same phase brought part of the Middle Penninic Schams Nappe Complex back towards SE over the Avers Nappe. In its southernmost part, a large normal fault (Turba Mylonite Zone) separates the Avers Nappe and the backthrust Schams and Tomül nappes in the footwall from the Platta and Malenco-Forno-Lizun nappes in the hangingwall.

The thin, discontinuous sedimentary Schafläger Nappe, locally overlain by crystalline rocks of the Rothorn Nappe, separates the Dorfberg Nappe from the overlying Schiahorn Nappe and Silvretta Nappe respectively. The Schafläger Nappe can be correlated with the Tschirpen Nappe.

The Maggia Nappe (together with the cartographic disjunct Sambuco Nappe) occupies the NNW–SSE oriented transverse synformal zone in the middle of the structural Lepontine Dome. It is made up of basement rocks intruded by Variscan granitoids (Late Carboniferous).

Deutsch: Salassikum
Français: Salassique
Italiano: Salassico
English: Salassic

The Salassic Domain groups the tectonic units derived from an extensional allochthon split off from the most distal part of the Adriatic margin during the Middle Jurassic opening of the Piemonte-Liguria Ocean and subducted below the Austroalpine and South Alpine units in Late Cretaceous times. These units – Dent Blanche, Mont Mary and Sesia nappes in western Switzerland and adjacent Italy, together with the Margna and Sella nappes in southeastern Switzerland and partly in Italy – are characterised by their high-pressure metamorphism.

This term stems from a Celtic tribe, the Salasses, who settled in the Valle d’Aosta and the Sesia region, at the same time as the Helvetians north of the Alps and the Lepontians between Val d’Ossola and Leventina.

Deutsch: Müsella-Schuppe
Français: Écaille du Müsella
Italiano: Scaglia del Müsella
English: Müsella Slice

The Müsella Slice is composed of the Müsella basement and an overlying band of strongly tectonized Mesozoic sediments (“Corn element”). This slice is considered part of the Bernina Nappe Complex mainly for structural reasons. Thereby the Müsella basement is correlated with the basement of the Julier Nappe while the Mesozoic sediments are correlated with the Ela Nappe on the north-western side of the Engadine Fault. The Mesozoic sediments of the Müsella Slice are overthrust by the Upper Austroalpine Languard Nappe. Alternatively, this slice could be considered as part of the Upper Austroalpine Languard Nappe.

Deutsch: Schlinig-Linie
Français: ligne de Schlinig
Italiano: linea di Slingia
English: Schlinig line

The Schlinig Thrust, located near the Switzerland-Austria-Italy triple point, is a major WNW-directed thrust within the Upper Austroalpine subdomain, which lead to the emplacement of the tectonically higher Ötztal Nappe Complex over the underlying S-charl-Sesvenna Nappe and the Campo Nappe Complex. It can be followed as an intra-basement shear zone all along the Etsch Valley (Vinschgau) eastwards for some 40 km.
