Fig. 2: Elemental ratios of different minerals and soil with different grain sizes versus their 36Ar concentrations.
From: Weak influence of the secondary surface processes on the regolith of Chang’E-5 landing site
a 4He/36Ar ratios plotted versus 36Ar concentrations. b 20Ne/36Ar ratios plotted versus 36Ar concentrations.The uncertainties (1σ) of the data are smaller than symbol sizes.
