Argon mantle concentrations

Nonradiogenic argon and xenon isotope concentrations of such a lower-mantle reservoir cannot be directly calculated without assuming either specific lower-mantle Ar/Ne and Xe/Ne ratios or argon and xenon isotopic compositions. Since modification of the noble gases in the atmosphere has occurred, the relative abundances of the interior of the Earth are unlikely to match those now observed in the atmosphere. For example, a closed-system lower mantle with "Xr/ Ar 3,000 (see Section 4.11.2.4) and 270 ppm K has " Ar= 5.7 X lO atoms g and so... [Pg.2207]
