Why is one rock melting, while the other is solid at the same depth and temperature?

Please explain what causes one of the rocks to melt and not the other. [Hint: What does the title of one of the graphs suggest has been added to the system?]
What will be an ideal response?


Rock Y is melting whereas rock X is not because melting temperature at a particular pressure is lower in the presence of water (wet melting) than in the absence of water (dry melting).
