Nitrogen and noble gas data for springs, fumaroles, basalts, and various crustal gases

Abstract: We use the rare 15N15N isotopologue of N2 as a novel tracer of air contamination in volcanic gas effusions. By constraining air contamination in gases from Iceland, Eifel (Germany), and Yellowstone (USA), we derive new estimates for mantle d15N (fractional difference in 15N/14N from air),...

Description
Summary:Abstract: We use the rare 15N15N isotopologue of N2 as a novel tracer of air contamination in volcanic gas effusions. By constraining air contamination in gases from Iceland, Eifel (Germany), and Yellowstone (USA), we derive new estimates for mantle d15N (fractional difference in 15N/14N from air), N2/36Ar and N2/3He.
