The Northern Calcareous Alps consists of a nappe stack made up exclusively of sedimentary rocks, ranging from the Permian to the Late Cretaceous, occupying the entire northern part of the Austroalpine. These nappes were detached from their crystalline basement during the Late Cretaceous, as inferred from synorogenic Cretaceous deposits. They were affected by top-NW thrusting in the Cretaceous, followed by top-N thrusting in the Cenozoic. This led to a complicated internal structure.

The Inntal Nappe is the lower tectonic unit of the Tirolic Nappe System (Upper Austroalpine) in the Northern Calcareous Alps. The stratigraphic sequence is characterised by thick Triassic deposits (up to 1700 m of Middle Triassic platform and basin sediments and over 2000 m of peritidal sediments of the Hauptdolomit Group).

The Lechtal Nappe is the upper tectonic unit of the Bajuvaric Nappe System (Upper Austroalpine) in the Northern Calcareous Alps. Its stratigraphic sequence is characterised by thick and widespread Jurassic and Cretaceous basin sediments, as well as local shallow sediments («Zürser Schwelle»).
In the northern Rätikon mountain range, between Austria, Liechtenstein and Switzerland, it is intersected by out-of-sequence thrust faults, which divided it into several slices (Schesaplana, Gorfion, Augstenberg, Ochsenkopf, Heubühl and Drei Schwestern slices) and also lead to the exposure of isolated lenses of the Arosa Zone. The «Northern Mittagspitz Zone», in the eastern Rätikon, and the Madrisa Slice, which is isolated north of Klosters between the Silvretta Nappe above and the Upper Penninic Arosa Zone below, are considered to be inverted slivers derived from the Lechtal Nappe.
