Figure 4.04. KAl(Si2O6)-SiO2 (Le-Silica) equilibrium phase diagram with the peritectic point labeled. The peritectic point due to the incongruent melting of sanidine is labeled. It gives the composition (42.2% SiO2) of a liquid that is saturated with both Lct and Sa at 1150°C. Interactive features are the same as those for Figure 4.03.
