  • The Quartz Page: Occurrence

     · Many show a dependency of their solubility on pressure. Upon directional pressure grains in a rock may change shape - not because they get deformed, but because material gets dissolved at crystal faces that lie perpendicular to the direction of the force and recrystallizes at the faces that lie parallel to the direction of force
