Phase diagrams assignment

1) The path of melting an Fo80 crystal (olivine with 80% Forsterite and 20% Fayalite) showing

a) the composition of the first drop of liquid,

b) composition of the last crystal before 100% melt,

c) the compositions of co-existing liquid and solid at a temperature of 1700 C and 1775 C,

d) the relative amounts of liquid and solid at 1700 and 1775 C.

2) The path of freezing of a 80% Diopside 20% Anorthite system showing

a), the temperature at which the first crystal forms,

b) the composition of the first crystal,

c) the relative amounts of solid and liquid at 1325 C,

d) how much liquid is left at a temperature just above the solidus,

e), the temperature of the lowest temperature liquid and its composition,

f) describe what happens to this eutectic liquid as it cools through the solidus
