Dissolution parameters of five nonradiogenic isotopes (AX) of nebular noble gases (3He, 22Ne, 36Ar, 84Kr, and 130Xe) into basaltic melt. The abundances of each isotope's ﹩{n}_{{\,}^{{\rm{A}}}{\rm{X}}}﹩ are taken from the analysis of M. Asplund et al. (2021). We use the elemental values of Henry’s constant kX (see Equation (12)) of G. Iacono-Marziano et al. (2010) for He, Ne, and Ar and the ones of A. Jambon et al. (1986) for Kr and Xe, evaluated at the melting temperature of the mantle Tmelt ≈ 1800 K (see Figure 3).
