Systematic elemental fractionation of mantle-derived helium, neon and argon in mid-oceanic ridge glasses
Based on the proposition that the Earth contains solar-like, nucleogenic and atmosphere-derived neon components, we calculate the amounts of solar-derived22Ne(s) and nucleogenic21Ne(*) present in a sample. The amounts of22Ne(s) and21Ne(*) can then be compared with the amounts of primordial3He and radiogenic4He. The3He/22Ne(s) and4He/21Ne(*) ratios observed in basaltic glasses from mid-oceanic ridges (MORBs) vary by almost 2 orders of magnitude and define a linear correlation with a slope of...[Show more]
