  9. Pegmatite - Wikipedia

    en.wikipedia.org/wiki/Pegmatite

    Granite requires a water content of 4 wt% at a pressure of 0.5 GPa (72,500 psi), but only 1.5 wt% at 0.1 GPa (14,500 psi) for phase separation to take place. [14] The volatiles (primarily water, borates, fluorides, chlorides, and phosphates) are concentrated in the hydrous phase, greatly lowering its viscosity. [5]
