What is Compositional dependence of H~2~O solubility along the joins NaAlSi~3~O~8~-KAlsi~3~O~8~, NaAlSi~3~O~8~-LiAlSi~3~O~8~, and KAlSi~3~O~8~-LiAlSi~3~O~8~ about?

The composition-dependence of the solubility of H20 in silicate melts along the binary joins NaAlSi30g-KAlSi30g, NaAlSi30g-LiAlSi30g, and KAlSi30g-LiAlSi30g has been determined at 2 kbar and 1040 0c. The study involved 1 atm dry oxide fusion, hydrothermal saturation, isobaric rapid quench and macroscopic analysis for H20 using Karl Fischer titration (KFT) and microscopic investigation of homogeneity using infrared absorption spectroscopy, respectively. The solubility of H20 in these melts increases in the order KAlSi30g (5.12 wt%) < NaAlSi30g (6.03 wt%) < LiAlSi30g (7.32 wt%). The total relative weight percent variation in solubility is 43%, which corresponds to a relative mole percent variation of 23%. Along the joins, small but systematic deviations from additivity are observed at the lu uncertainty level. These deviations are positive on the NaAlSi30g-KAlSi30g join but negative on the LiAlSi30g-bearing joins. The present results confirm the early suggestion of Voigt et al. (1981) that solubility variation along the NaAlSi30g-KAlSi30g join is nonlinear and disagree in detail with the equimolal approximation of Burnham (1975Burnham ( , 1981) ) and Burnham and Davis (1974).
