Popis: Highlights (1) The rocks of the study area consists of fine-grained garnet meta-mafic (FGM) and coarse-grained garnet meta-mafic (CGM) rocks presenting partial melting and metamorphic features characterizing the amphibolite-granulite facies transition; (2) Fine-grained garnet meta-mafic (FGM) have been reworked during Eburnean whereas coarse-grained garnet meta-mafic (CGM) formed at the Eburnean; (3) The partial melting and metamorphic peak occurred around the amphibolite-granulite facies transition between 2.7–14.89 kbar and 672–952 °C for the FGM and around 1.5–16.09 kbar and 631–909 °C for the CGM. Meta-mafic rocks protolith displays basaltic composition and emplaced at an active continental margin context under high oxidizing conditions.
