“…These nappes overlie the Para-Autochthonous units, which are mainly composed of quartzites, micaschists and scarce Ordovician orthogneisses. No early high-pressure relics are observed in the Para-Autochthonous units, which variably underwent lower and upper amphibolite-facies metamorphism (Ledru et al 1989(Ledru et al , 1994Quenardel et al 1991;Santallier et al 1994;Faure et al 2005Faure et al , 2009. The thrusting of the UGU over lower grade units is considered to be responsible for an inverted metamorphic stratigraphy ("inverted metamorphism") which is widespread and typical of several regions in the French Massif Central, such as the Aigurande (Rolin and Quenardel 1980), Marvejols (Briand 1978), Rouergue (Burg et al 1989), Limousin (Friedrich et al 1988;Roig and Faure 2000;Bellot and Roig 2007), Haut-Allier (Marchand 1974;Burg 1977;Burg et al 1984;Schulz et al 1996) and La Sioule (Faure et al 1993;Schulz et al 2001;Schulz 2009).…”
