“…In the Hercynian Serre and Sila massifs of Calabria (southern Italy; Figure 1a), the pressure peak was reached during the Upper Mississippian to Lower Pennsylvanian (Acquafredda, Lorenzoni, & Zanettin Lorenzoni, 1994;Festa et al, 2012;Fornelli, Pascazio, & Piccarreta, 2011;Langone et al, 2010;Micheletti, Fornelli, Piccarreta, Barbey, & Tiepolo, 2008). Subsequently, decompression and exhumation of the thickened continental crust was accompanied by large volumes of granitoid emplacement leading to the Serre batholith (De Vivo et al, 1992), that occurred during the Upper Pennsylvanian-Early Permian at intermediate crustal levels (Caggianelli, Prosser, & Di Battista, 1997;Caggianelli, Prosser, & Rottura, 2000;Graessner & Schenk, 2001;Langone, Caggianelli, Festa, & Prosser, 2014;Langone et al, 2010). The Serre batholith is underlain in the north by a granulite facies basement ( Figure 1a) with maximum pressures of ~0.9 GPa recorded in the migmatitic metapelite (Fornelli et al, 2011;Figure 1b), whereas it is overlain in the south by the low-P Stilo-Pazzano Phyllite Unit and by the Mammola Paragneiss Unit (Figure 1a).…”
