20Ne/22Ne versus 21Ne/22Ne for total integrated Ne data. The shaded arrow represents mass fractionation line from SW-Ne (e.g. Grimberg et al., 2008). The fractionation line is close to a mixing line between SW and air. The isotopic ratios for cosmogenic Ne are 20Ne/22Ne ≈ 0.85 and 21Ne/22Ne ≈ 0.90 (Eugster et al., 1993). Errors are 1σ.
