Research output: Contribution to journalArticlepeer-review


Fluid inclusions in the leucosomes of Wadi Feiran migmatites showed that CO 2, H2O and (H2O-CO2) fluids were likely to have been present when partial melting began in these rocks. Low salinity, aqueous fluid, to a lesser extent, CO2-rich fluids are the most abundant fluids. The present study suggests that high-density CO 2 inclusions were formed at the earliest stage, while H2O inclusions were formed at the late stage. In an intermediate stage, low-density CO2 and H2O, CO2 inclusions were formed. At the early stage of uplift and during melt crystallization, the CO 2-bearing vapour was trapped at grain boundaries. At the late stage of uplift, H2O released at the time of crystallization of the melt was trapped as inclusions.
