  • Quartzite ~ Learning Geology

    What is Quartzite? Quartzite is a nonfoliated metamorphic rock that formed by the metamorphism of pure quartz sandstone. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other resulting in very hard and dense quartzite.
