Summary:Fluid inclusions in quartz veins from sillimanite-zone metasediments in Connemara show that H2O, CO2 and CH4 were likely to have been present when melting began in the higher-grade rocks immediately to the south. MS also indicates the presence of N2 in many samples, with a correlation between N2 and CH4. It is believed that virtually all the fluids found were produced by metamorphism of the Dalradian sedimentary sequence. [R.A.H.]
