Argon isotope constraints on modification of oxygen isotopes in Iceland Basalts by surficial processes

New data from the Reykjanes Peninsula, Iceland, show that ^3He/^4He ratios of subglacial basaltic glasses are well correlated with CaO/Al_2O_3. High CaO/Al_2O_3 ratios are likely due to assimilation of lower crustal clinopyroxene and the large variations in ^3He/^4He likely result from addition of c...
