Analyses of He, Ar and CO2 in individual vesicles from two basaltic glasses from the mid-Atlantic Ridge show that volatile compositions in basaltic glass vary from vesicle to vesicle. This volatile fractionation is consistent with Rayleigh-type fractional degassing from the magma, producing a well-defined evolution in the magmatic volatile compositions. Volatile fractionation during vesicle formation may be superimposed on the overall Rayleigh degassing trend of one of the samples. Estimates of… CONTINUE READING
