Question 4. The figure below illustrates the Forsterite-Enstatite-Silica system. Label the six fields (there is no solid solution between any of the minerals). Describe the sequence of events that occur when a liquid of composition C is cooled to temperature T4. Note in particular what happens at temperature 1-4. Assume full equilibration (slow cooling and no separation of liquid and solid phases). T L Tz 2 T (°C) P . T3- E T4 50 Mg2SiO4 Mg2Si206 Forsterite Enstatite Xsio2 SIO2 Quartz
