p.48: The Pizzo del Vallone Nappe surrounds the Monte Leone Nappe mainly in the large synformal Berisal Backfold (Carrupt 2003). It is composed of a detrital sedimentary series covering the entire Mesozoic and possibly the Paleogene, characterized by Jurassic basaltic rocks. In the western part of the nappe, both north and south of the Monte Leone Nappe, occur the crystalline basement of these metasediments.
