Temperature C 1890 1800 1600 1400 1200 Liquid Olivine 0 20 40 60 80 100 Mg2SiO4 Fe2SiO4 Weight % Fa Fo Fa Assume equilibrium crystallization. Start with a composition of 40% Mg2SiO4/60% Fe2SiO4. 1) What temperature will crystallization begin? 2) What is the composition of the phase that crystallizes first? 3) What is the composition of the melt at 1500°C? 4) What is the temperature that crystallization will end? 5) What is the composition of the last bit of melt at the end of crystallization? 1205
