Deutsch: Koralpe-Wölz-Deckenkomplex
Français: Complexe de nappe de la Koralpe-Wölz
Italiano: Complesso di falde della Koralpe-Wölz
English: Koralpe-Wölz Nappe Complex

The Koralpe-Wölz Nappe Complex is a high-pressure tectonic unit situated at the level of the Schlinig Thrust.

The “Walser Slice” in the Rätikon area (northeastern corner of the Prättigau Half-Window) corresponds to the Rothorn Nappe (Bernina Nappe Complex).

Deutsch: Obere Orobische Decke
Français: Nappe Orobique supérieure
Italiano: Falda Orobica superiore
English: Upper Orobic Nappe

The Upper Orobic Nappe is the uppermost and oldest thin-skinned thrust sheets of the eastern South Alpine domain. It consists of an around 5 to 7 km thick basement sheet, arranged in a series of en-échelon anticlines. The thrusts associated with the Upper Orobic Nappe ramped into the sedimentary cover, creating several duplexes that occur in a belt of klippes. The distribution of these erosional remnants reflects the later deformation by the basement ramps of the underlying younger local thrust sheets and imbricates (Lower Orobic Imbricates).

Italiano: Milano Belt
English: Milan Belt

The Milan Belt represents the southernmost (i.e. most external) and lowest thin-skinned thrust sheets of the eastern South Alpine domain west of Lago di Garda. Its basement ramps are hidden below the Po Plain like most of the deformed sedimentary cover. The Milan Belt consists of thrust imbricates, locally inverting Mesozoic high-angle faults, developed as a frontal accretion of the western South Alpine domain during the Miocene.

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

The Corvatsch Slice, located southeast of the Engadine Fault, can be seen as the equivalent of the Err Nappe. It is predominantly made up of intensely deformed pre-Mesozoic basement. Its Mesozoic cover is only rarely preserved just below the overlying Bernina Nappe (e.g., at Fuorcla Surlej).

Deutsch: Schwarzwald-Massiv
Français: Massif de la Forêt Noire
Italiano: Massiccio dello Schwarzwald
English: Schwarzwald Massif

The Schwarzwald Massif exposes the basement of the South German Platform. It consists mainly of metamorphic and plutonic rocks, with some remnants of Late Paleozoic sediments. It is separated from the Upper Rhine Graben by a major normal fault (Schwarzwald Fault).

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.

English: Internal Aar Massif

The Internal Aar Massif is restricted to a thin band situated south of the Rote Kuh-Gampel Shear Zone and its possible continuation between Aletsch and Rhône glaciers. It is subdivied into two submassifs: the Baltschieder-Gletsch Submassif in upper Valais region, and the Trun-Punteglias Submassif in the Surselva (Graubünden), with an autochthonous sedimentary cover preserved in part locally.

The Calanda Slice is a post-nappe tectonic slice (due to a late out-of-sequence thrusting) of the parautochthonous cover of the northeastern end of the Aar Massif.
