p.96: The hangingwall of the Ortler Nappe is defined by the Trupchun-Braulio Thrust that formed during a later stage of the Cretaceous orogeny. This thrust juxtaposes the Quattervals Nappe (in the west) and the Umbrail-Terza Slice Complex (in the east) over the Ortler Nappe. The thrust is marked by calcite mylonites derived from the footwall and exhibits numerous top-WNW sense-of-shear indicators (Conti 1997).
