Abundance of OH groups and molecular H 2 O as a function of water concentration and temperature. (A) Evolution of abundance of OH groups and molecular H2O as a function of total water concentration in quenched melts (quenched from 1,100°C at 200 MPa pressure) of compositions indicated (data from Zotov and Keppler 1998). (B) Abundance of OH groups and molecular H2O in haplogranite composition glass and melt as a function of temperature from Nowak and Behrens (1995) recorded in situ while the sample was at the temperature of interest as shown with the pressure constant at 150 MPa.
