Fig. 2: Partition coefficients of noble gases from calculations and the liquid-melt partition model.
From: Primitive noble gases sampled from ocean island basalts cannot be from the Earth’s core
Partition coefficients (concentration in weight) of noble gases between liquid Fe and silicate melt at 50 GPa, 3500 K and 135 GPa, 4200 K, plotted against the bond-length ratio of Mg–X to Mg–O (denoted as r and r0). Filled circles and squares are our calculated data from ab initio thermodynamics and the lines are from fitting the Lennard-Jones model. Fitted parameters can be found in Supplementary Information.
