p.94: The Masuccio Nappe is the lowermost nappe, consisting exclusively of amphibolite-facies Variscan basement. This basement nappe overthrusts the Bernina Nappe and is located in the footwall of the Late Cretaceous Mortirolo Normal Fault (Meier 2003), a transtensional top-E directed extensional fault that became folded around the Pass d’Ur Antiform during Cenozoic folding. In the south, the Masuccio Nappe is in a subvertical orientation and part of the Southern Steep Belt (or root zone) located north of the Tonale Fault. There it is juxtaposed with the structurally much higher Tonale Nappe, located further south and directly adjacent to the Tonale Fault. East of Lago di Poschiavo, the Mortirolo Normal Fault, defining the top of the Masuccio Nappe, abuts the basal thrust of the Campo Nappe Complex that overlies the Lower Austroalpine Bernina Nappe.
