What is Quartzite? Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz.It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
