Quartzite is formed from contact metamorphism. Quartzite is formed when
sandstones rich in quartz are physically altered by heat and pressure through
the process of contact metamorphism. The conditions are responsible for
re-crystallizing the sand grains compactly together to withstand slight and
moderate physical pressure.
