Figure 15From: Water-melt interaction in hydrous magmatic systems at high temperature and pressure Relationship between degree of polymerization, NBO/T (T = Al + Si), of aluminosilicate melts. As a function of the total water content for different values of the Al/(Al + Si) of the melt at 1.5 GPa and 1,400°C. Data from Mysen (2007).Back to article page
