Is there solar argon in the Earth's mantle?
Article Abstract:
Latest research suggests that solar argon, xenon and krypton are only a minor element of the rare gases of the Earth's mantle, if they are present at all. It appears that solar argon, if present at all, is only a very small constituent of the upper-mantle non-radiogenic argon budget. It is likely that this is also the case for the more primitive source of the hotspots. It may be that most 38Ar and 38Ar present in the mantle may have been re-injected from the atmospheric reservoir into the mantle.

Low argon solubility in silicate melts at high pressure
Article Abstract:
Research shows that the neon gas argon becomes decreasingly soluble with increasing pressure. The solubility of argon in olvine melt at varying pressures is being assessed using revised geochemical models because the validity of previous research techniques are being questioned. The solubility of argon in silicate melts is illustrated.
