Roter, gelber und grüner Dolomitmergel bis Tonschiefer (z.T. an der Basis mit dem liegenden «Heller Dolomit» wechsellagernd). Die grünlichen Varietäten sind serizitisch und stark quarzhaltig.

The Préalpes Médianes Rigides form the internal part of the Préalpes Médianes Nappe (mainly located in the Romandes Prealps), which consists of large imbricates.

Deutsch: Marzio-Störung Français: Faille de Marzio Italiano: Faglia di Marzio English: Marzio Fault
The Marzio Fault separates the WSW–ENE trending Arbostora Anticline (southern part of the Varesotto Imbricates) from a complex syncline of imbricated Mesozoic sediments.
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: Schafläger-Decke Français: Nappe du Schafläger Italiano: Falda dello Schafläger English: Schafläger Nappe
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.
Deutsch: Maggia-Decke Français: Nappe de la Maggia Italiano: Falda della Maggia English: Maggia 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: 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.
