- In short
-
The Lower Austroalpine Carungas Slice, consisting of a band of predominantly overturned Mesozoic sediments and its associated crystalline basement, forms the hangingwall of the Platta Nappe and the footwall of the Err Nappe. This slice extends from east of Savognin all the way to the Julierpass road above Bivio, along the western margin of the Err Nappe (Manatschal & Nievergelt 1997, their “lower Err Nappe”). The small portion of crystalline rock wedged between the two branches of the Engadine Fault near Sils Maria is also related to the Carungas Slice. This slice is derived from the most distal part of the former Adriatic continental margin.

- informal term
- In short
-
The Chastelets Slice, located southeast of the Engadine Fault, is a small slice of basement and cover in the footwall of the Corvatsch Slice. It directly overlies the Platta Nappe and hence occupies a similar position to that of the Roccabella Slice northwest of the Engadine Fault.

- In short
-
The Murtiröl Slice, consisting of basement and cover, forms a dome-like feature in the footwall of an important extensional detachment. This detachment fault and the adjacent Engadine Fault separate the Murtiröl Slice from all the surrounding units belonging to either the Bernina Nappe Complex (in the northwest and southwest) or to the Upper Austroalpine Languard and Ortler nappes (in the east and northeast).
