Thermobarometric modelling of metapelitic sample MCE338 located in the Cortical Pelvoux. (A) Chemical profile of a garnet. (B) T-XH₂O diagram calculated with a pressure of 0.5 GPa, the mineral assemblage of the sample indicates a H₂O content of 1.47 wt%. (C) Pseudosection calculated in the MnNCKFMASH system. Modelling of the Qcmp factor of the mineral composition of (D) biotite based on MgO, FeO, MnO, Al₂O₃ and SiO₂ contents, (E) muscovite based on Na₂O, K₂O, CaO, Al₂O₃, FeO, MgO and SiO₂ contents, and (F) plagioclase based on K₂O, Na₂O, CaO, Al₂O₃ and SiO₂ contents (Tab. S2). Bi: Biotite; Mu: muscovite; Crd: Cordierite; Kfs: K-feldspar; Pl: Plagioclase; Gt: Garnet; and: Andalousite; ky: Kyanite; sill: Sillimanite; Opx: Orthopyroxene; q: Quartz; melt: silicate liquid.
