Quartzite

• Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures.

• Quartzite is one of the most physically durable and chemically resistant rocks found at Earth's surface. When mountain ranges are worn down by weathering and erosion, less-resistant and less-durable rocks are destroyed, but the quartzite remains.

• Pure quartzite is white but quartzite exists in a wide variety of colors.

• Due to how Quartzite is formed, it is common for imperfections to be found, which results in its different colorations.

• Due to quartzite's density, it was formed into rounded blades for cutting.

• While blades formed from quartzite were not as sharp as what other materials could. produce, they were durable enough to withstand more force, which resulted in their use as arrowheads.

• Due to the toughness of the stone, it makes it easy to spot among imposters.

• Resistant to Acids.

• Ranks 7 on the Mohs hardness scale.

• Quartzite is extremely versatile and can be used both indoors and outdoors. It can be used in many different shapes and forms including landscaping.

• Unfortunately, the same durability that makes quartzite a superior construction material also limits its use. Its hardness and toughness cause heavy wear on crushers, screens, truck beds, cutting tools, loaders, tires, tracks, drill bits, and other equipment. As a result, the use of quartzite is mainly limited to geographic areas where other aggregates are not available.

In the United States, formations of quartzite can be found in some parts of Pennsylvania, the Washington DC area, eastern South Dakota, Central Texas, southwest Minnesota, Devil’s Lake State Park in the Baraboo Range in Wisconsin, the Wasatch Range in Utah near Salt Lake City, Utah.
