    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.
