Summary:New data are reported for samples along the SiO2-NaAlSiO4 join, including bulk analyses and characterization by a range of spectroscopic techniques; experimental methods and analytical techniques are described in detail, and important IR, Raman and NMR spectral features of dissolved C-O species for the range of SiO2-NaAlO2 glasses are illustrated. For the P (10-25 kbar) and T (1450-1700°C) conditions used, the solubility of CO2 along the join NaAlO2-SiO2 decreases from rhyolite to jadeite, then increases to nepheline apparently related to the concentrations of the individual species. The T dependence of solubility differs with composition, with Ne showing a positive T dependence, Jd a negative T dependence from 1450 to 1600°C. SiO2-rich compositions have a CO2 solubility insensitive to T. Although melt speciation changes during quenching, some of the high T speciation may be preserved. [R.K.H.]
