p.91: In the northern Rätikon mountain range, between Austria, Liechtenstein and Switzerland, the Lechtal Nappe is intersected by out-of-sequence thrust faults, which in places lead to the exposure of isolated lenses of the Arosa Zone. Such thrust faults divide the westernmost Lechtal Nappe into several slices (the Schesaplana, Gorfion, Augstenberg, Ochsenkopf, Heubühl and Drei Schwestern slices; Allemann 2002). The “Northern Mittagspitz Zone”, in the eastern Rätikon (Nagel 2006), and the Madrisa Slice, which is isolated north of Klosters between the Silvretta Nappe above and the Upper Penninic Arosa Zone below, are considered to be inverted slivers derived from the Lechtal Nappe.
