p.91: A nappe stack consisting exclusively of sedimentary rocks, ranging from the Permian to the Late Cretaceous, occupies the entire northern part of the Austroalpine in the Northern Calcareous Alps. These were detached from their crystalline basement during the Late Cretaceous, as inferred from synorogenic Cretaceous deposits (Ortner & Kilian 2022). They were affected by top-NW thrusting in the Cretaceous (Hauterivian to Turonian, Ortner & Kilian 2022), followed by top-N thrusting in the Cenozoic. This led to a complicated internal structure. From bottom to top these nappes were classically grouped into Bajuvaric, Tirolic-Noric and Juvavic nappe systems, a concept that is presently under discussion (Ortner & Kilian 2022). In the area of the Tectonic Map of Switzerland, from bottom to top, the Cenoman-Randschuppe, the Allgäu Nappe and the Lechtal Nappe belong to the Bajuvaric Nappe System, the Inntal Nappe and the Krabachjoch Nappe to the Tirolic-Noric Nappe System.

The Krabachjoch Nappe is the upper tectonic unit of the Tirolic Nappe System (Upper Austroalpine) in the Northern Calcareous Alps. It has an exclusively Triassic stratigraphic sequence ranging from «Alpiner Buntsandstein» (Chazforà-/Fuorn-Fm.) up to «Hauptdolomit».

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).
