Time-scales of fluid infiltration events in the crust and mantle remain largely unknown, suggesting a wide range of uncertainties. This study aims to clarify Cl-bearing fluids infiltration at crustal conditions by multiple trace elements profiles in apatite from fluid-rock reaction zones in the mafic granulite and amphibolite samples from Mefjell, Sor Rondane Mountains (SRM), East Antarctica, collected in JARE-51. Mafic granulite and amphibolite are partially hydrated along veins at 750-620 MPa and 650-500 °C, and associated with mm-sized hydration reactions zones.
