Solubility of noble gas in silicate melt under high pressures is important for understanding the origin of the Earth's atmosphere and evolution of the Earth's interior. In this article, previous studies of noble gas solubility based on high pressure experiments are reviewed. Then we present new experimental results on Ar solubility in silica melt up to about 12 GPa by using a laser-heated diamond-anvil cell (LHDAC). It was found that solubility of noble gas increased and then saturated with increasing pressure, which is completely different from the results of previous LHDAC experiments. The source of discrepancy and problems of solubility measurements using LHDAC are discussed.
