Quartzite is a naturally occurring metamorphic rock composed mainly of quartz, which is a mineral that belongs to the group of silicate minerals. It forms when sandstone is subjected to intense heat and pressure deep within the earth's crust. This process causes the sand grains in the sandstone to recrystallize and fuse together into a dense, hard rock.
Quartzite is a very hard and durable rock that is resistant to both chemical and physical weathering. It is commonly used in construction and landscaping applications because of its durability and attractive appearance. Quartzite is often used as a building stone, flooring material, and as a decorative stone in gardens and landscapes.
