Geochronological and tectono-metamorphic interpretations for the Pelvoux Massif. (a) P-T-t path of sample MCE338 inferred from the mineral assemblage and mineral compositions and from textural features of monazite. (b) P-T-t path of sample MCE339v inferred from the mineral assemblage and biotite composition and from textural features of monazite. (c) P-T-t conditions from the Pelvoux Massif. P-T-t paths of the Cortical Pelvoux are from this study. P-T data from metabasites of the Inner Pelvoux are from Jacob et al. (2022) and Grandjean et al. (1996). P-T conditions of Crd-migmatites are theoretical and age corresponds to monazite age of sample MCE314 from this study. (d) Geochronological results constraining the ages of D₁, D₂ and D₃ from this study, (Fréville et al., 2018; Fréville, 2016). (e) Inferred tectono-metamorphic evolutions of the Cortical and Inner Pelvoux.
