p.85: The Err Nappe (s. str.) is confined to an area northwest of the Engadine Fault (see § 10.5) between Albulapass and Julierpass where it overlies the Carungas Slice (Stöcklin 1949), both traditionally being referred to as “Err-Carungas Nappe”. The Bardella-Roccabella Slices are also located northwest of the Engadine Fault. It is convenient to group the equivalents of similar slices southeast of the Engadine Fault (Corvatsch, Chastelets and Murtiröl slices) together into the Err Nappe Complex. The latter slices are substantially displaced in respect to the “Err-Carungas Nappe” and the Bardella-Roccabella Slices by a sinistral strike-slip motion along the Engadine Fault, combined with relative uplift of the southeastern block (Schmid & Froitzheim 1993).

    The Err Nappe is a Lower Austroalpine tectonic unit confined to an area northwest of the Engadine Fault between Albulapass and Julierpass where it overlies the Carungas Slice. Towards the south it is separated from the Julier Nappe (Bernina Nappe Complex) by a multiply deformed synclinorium, the so-called “Samedan Zone”.

    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.
