  • Quartzite Rock Formation, Uses, Properties and Occurrence

    Quartzite is a metamorphic rock made from quartz sandstone, a sedimentary rock predominantly composed of the silicate mineral quartz. The chemical composite of the quartz minerals is silicon dioxide, written SiO2. The metamorphic forces of heat and pressure force the quartz minerals to bind together and crystallize into a strong matrix.
