Figure 21From: Water-melt interaction in hydrous magmatic systems at high temperature and pressure Temperature (1/T) vs. ln K relationship for the equilibrium, 2 Q1 ⇌ Q0 + Q2 , (Equation 10). From the system SiO2-H2O with aqueous fluid in equilibrium with quartz (lower pressure) or coesite (higher pressure). Data from Mysen et al. (2013).Back to article page
