Description

Description

Furrer et al. 1985: "Mainly basement rocks with scant Mesozoic sediments. As already mentionned, the Languard nappe has structural and facies affinities with the Lower Austroalpine units."

Wurde füher als «Mittelostalpin» interpretiert, d.h. strukturell und faziell am Übergang zwischen Unter- und Oberostalpin.

Definition

Gouffon Yves (Editor) (2024) : Tectonic Map of Switzerland 1:500000, Explanatory notes. Federal Office of Topography swisstopo, Wabern

p.92: The basement-dominated Languard Nappe covers a relatively small area. It is surrounded by the Engadine Fault in the northwest and lacks an equivalent on the northwestern side of this fault. It overthrusts the Bernina Nappe in the south, while in the north it overlies the Mezzaun Slice of the Bernina Nappe Complex and the Murtiröl Slice of the Err Nappe Complex; the thrust contacts being overprinted by normal faults (e. g., the Mezzaun Normal Fault; see § 8.1.1 and 8.1.2) over large distances. To the east and northeast the Languard Nappe is overthrust by the basement of the Campo Nappe Complex and by the Ortler Nappe, which both occupy a higher tectonic position (Conti 1997).
