Quartzite is a hard, metamorphic rock that originates from sandstone. It forms when sandstone is subjected to high heat and pressure over time, typically during tectonic compression within orogenic (mountain-building) belts. Here’s an overview of its properties, formation, and uses:

Uses of Quartzite

Quartzite’s durability and aesthetic appeal make it valuable in various applications:

1. Construction Material:
   • Used as crushed stone for road building, railway ballast, and construction aggregate.
   • In high-wear areas like stair steps and countertops.
2. Decorative Stone:
   • Polished quartzite is used for flooring, wall cladding, and as a decorative element in architecture.
3. Industrial Uses:
   • Ground quartzite can be used as a filler in paints, rubber, and ceramics.
4. Landscaping:
   • Often used in gardens and as decorative gravel.
5. Historical Use:
   • In ancient times, quartzite was used to make tools due to its sharp edges when fractured.
