Français: Écaille de la Casanna
Italiano: Scaglia della Casanna
English: Casanna Slice

The Casanna Slice is considered as an independant tectonic klippe correlated with the Err Nappe Complex and overlying the Arosa Zone. It is made up of a sedimentary series of Lower Austroalpine affinity.

The Wissenwand Slice, composed of Late Jurassic limestone (Quinten Formation), forms the base of the Drusberg Nappe in the Muotatal, where it underlies the Palfris Formation of the main part of the nappe.

English: Schabell Mélange

The Schabell Mélange formed at the footwall of the Upper Helvetic basal thrusts. It lies on top of the parautochthonous flysch of the Aar Massif, Blattengrat and Sardona nappes, below the Glarus Thrust. This mélange consists of a “wildflysch” with many lenses and slices of rock stemming from the immediately underlying units.

Deutsch: Mittelpenninikum
Français: Pennique moyen
Italiano: Pennidico medio
English: Middle Penninic

The Middle Penninic subdomain comprises tectonic units located between the Lower Penninic subduction surface and the major thrust of the Upper Penninic. Paleogeographically, these units are derived from the Briançonnais Terrane. They are formed of a polycyclic crystalline basement, cut by Late Cambrian (ca. 500 Ma) and Permian (ca. 270 Ma) granitic intrusions, by Permo-Carboniferous sediments that filled narrow basins and a characteristic Mesozoic – Paleogene sedimentary cover (much of it detached at the level of the Triassic evaporites to form some of the nappes in the Prealps).

Italiano: Pennidico Medio esterno della Svizzera orientale
English: External Middle Penninic of Eastern Switzerland

In the Prättigau Half-Window, the discontinuous and often very thin Middle Penninic nappe stack (Falknis and Sulzfluh nappes) is upright and overlies the Lower Penninic Tomül Nappe. It is overlain by the Upper Penninic Arosa Zone and the Austroalpine domain. The sedimentary facies of the Falknis Nappe have close similarities with the Tasna Nappe exposed in the Lower Engadine Window. The Mesozoic strata in all these Middle Penninic units can definitely be attributed to the Briançonnais paleogeographic realm.

In Central Switzerland, the external part of the Lower Penninic subdomain is represented by flysch nappes of controversial origin (from west to east: Schlieren, Wägital, Üntschen, Sigiswang and Oberstdorf nappes, as well as Triesenberg Slice Complex).

English: Internal Lower Penninic of Eastern Switzerland

In Eastern Switzerland, the internal part of the Lower Penninic subdomain is represented by metasedimentary, mostly shaly-calcareous units (so called “Bündnerschiefer”, incl. in the Prättigau Half-Window and the core of the Lower Engadine Window), deposited in the oceanic Valaisan Basin. Ophiolitic remnants are found at the base of some of the “Bündnerschiefer-type” nappes.

Within the Landeck Quarzphyllites, the «Puschlin Zone» encompasses very small lenses of Permo-Carboniferous and Early Triassic slivers (metaconglomerates, metasandstones and phyllites, as well as cataclasites).

The Ruginenta Nappe is a Middle Penninic tectonic unit of the Western Alps, occuring between the Moncucco Nappe and the Camughera Nappe in the huge Vanzone Antiform (south of the Simplonpass). It consists of a polycyclic basement intruded by a granite and overlain by a Carboniferous–Triassic sedimentary cover.
