Cosmogenically enriched ^(38)Ar/^(36)Ar ratios are detectable in Ca-bearing terrestrial samples, and are resolvable from a uniform background value of 0.18826±0.00018 for materials lacking nucleogenic or kinetic mass fractionation effects. Relationships between ^(38)Ar/^(36)Ar and cosmogenic ^3He i...
