  • Quartzite Wikipedia

    It is harder and more resistant to stains than granite. Crushed quartzite is sometimes used in road construction. High purity quartzite is used to produce ferrosilicon, industrial silica sand, silicon and silicon carbide. During the Paleolithic, quartzite was used, along with flint, quartz, and other lithic raw materials, for making stone tools.
