Deutsch: Vogesen-Massiv
Français: Massif des Vosges
Italiano: Massiccio dei Vosgi
English: Vosges Massif

The Vosges Massif exposes the basement of the Haute-Saône Platform. It consists of pre-Mesozoic rocks, including Variscan magmatites and metasediments, pre-Variscan metamorphic rocks and, on the southwestern side of the Upper Rhine Graben, unconformably overlying Permo-Carboniferous sediments.

Deutsch: Rhenodanubische Flysch-Zone
Français: Zone du flysch rhéno-danubien
English: Rhenodanubic Flysch Zone

The Rhenodanubian Flysch Zone (Mattern 1999) is a flysch belt in Lower Penninic tectonic position and considered to originate from the Valaisan paleogeographical realm. It comprises the Üntschen, Sigiswang and Oberstdorf nappes to the west and extends eastwards all the way to Vienna. The age of the Rhenodanubian Flysch is constrained to the period between the Early Cretaceous and the Paleocene.

Français: «Synclinal de Chamonix»
Italiano: «Sinclinale di Chamonix»
English: «Chamonix Syncline»

The «Chamonix Syncline» is a thin band of Mesozoic sediments separating the Aiguilles Rouges Massif to the north-west and the Mont Blanc Massif to the south-east. Most of these sediments can be considered as belonging to the cover of the Mont Blanc Massif, although this zone probably hides important tectonic contacts, including a probable SW extension of the Rhône-Simplon Fault.

English: Chropfsberg–Pizalun Slices

The Chropfsberg-Pizalun Slices are four isolated Lower Helvetic tectonic slices situated south of Sargans on the top of the nappe stack made up of the Blattengrat, Sardona and Bad Ragaz nappes. They include Triassic, Jurassic and Cretaceous strata and occupy the same structural position as the Tschingelhörner Slices, but without direct contact with the Glarus Thrust due to erosion.

Deutsch: Roselette-Decke
Français: Nappe de Roselette
Italiano: Falda di Roselette
English: Roselette Nappe

The Roselette Nappe is a small Upper Helvetic tectonic nappe situated around the southwestern end of the Mont Blanc Massif. It consists of similar basement and sediment rocks as the Mont Chétif Nappe and occupies a similar structural position above the crystalline basement and sedimentary cover of the Mont Blanc Massif. It is characterized by the presence of several internal thrust faults.

Deutsch: S-charl-Oberbau

Within the S-charl-Sesvenna Nappe, the “S-charl-Oberbau” (referred to as Tavrü Slice) consists entirely of a Norian to Cretaceous succession, volumetrically dominated by an over 2 km thick Hauptdolomit. It is completely detached from the Carnian Raibl Group. This slice, separated from the tectonically higher Ötztal Nappe by the Schlinig Thrust, suffered substantial internal extension in a domino-style.

Deutsch: Stammerspitz-Schuppe
Français: Écaille du Stammerspitz
Italiano: Scaglia dello Stammerspitz
English: Stammerspitz Slice

At the rim of the Lower Engadine Window, the Stammerspitz Slice is made up of a sedimentary series with a Lower Austroalpine affinity. Due to its location as a klippe directly above the Roz-Champatsch Mélange, this slice can be interpreted either as the lowermost unit of the Lower Austroalpine or as a sliver within this mélange or even within the Fimber Zone.

Deutsch: Subvulkanischer Körper vom Colle Gallo
Français: Coprs subvolcanique du Colle Gallo
Italiano: Corpo subvulcanico del Colle Gallo
English: Colle Gallo Subvolcanic Body

The Colle Gallo Subvolcanic Body, situated near Albino (northeast of Bergamo), encompasses many sills and small magma bodies of andesitic composition intruded the Lower Orobic Imbricates and the Upper Orobic Nappe. The unit is associated with normal faults and cut earlier thrusts. Intrusion ages around 40 Ma and geochemical analyses suggest a close relationship with the earliest Adamello intrusion stages.

The Lower Penninic Sigiswang Nappe, occuring east of the Rhine, is located north of the Säntis Nappe. It is made up of the Late Cretaceous Vorarlberg Flysch and is one of the westernmost occurrences of a flysch belt referred to as the Rhenodanubian Flysch Zone (Mattern 1999). Several klippes overlying the Liebenstein Nappe, resp. the Wildhaus Mélange in a few synforms within the Upper Helvetic Säntis Nappe are also attributed to the Sigiswang Nappe (from east to west: Müselalpe, Hohe Kugel and Fähnerenspitz).
