Fig. 14

Abundance ratio, CO3/HCO3, as a function of temperature (and pressure, see Table 1) in silicate–C–O–H–N melts. The straight line is least squares fitted to the expression, ln(CO3/HCO3) = − 13,738 ± 2680/T + 17 ± 3, r2 = 0.95. Also shown are the experimental data from an aluminosilicate–COH system under similar conditions from Mysen (2015a). Note that the label on the y-axis in the original plot in Mysen (2015a) was inverted. This is corrected for the present figure. The regression line for that regression is ln(CO32/HCO3-) = − 1999 ± 367/T + 0.9 ± 0.4, r2 = 0.94
