In this knowledge-rich series of knowing natural stone, we are going to see Quartzite rocks. It is a sedimentary type of rock and has immense commercial values in different industries, particularly in the construction field. 

What Is Quartzite Natural Stone

According to geology, quartzite is a metamorphic rock consisting mainly of quartz. 

How Is Quartzite Formed?

When the metamorphic process takes place on the quartz-rich sandstone, heat, pressure, and chemical influence enforce the recrystallization of sand grains. 

What Are Properties of Quartzite Natural Stone?

Moreover, silica cement binds those sand grains into a network of interlocking quartz grains with impressive strength. Therefore, when you measure quartzite on Moh’s scale, you will get 7.0, which is even higher than granite! Thus, quartzite stones are hard, tough, and durable natural stones in the construction industry.

Combination of other minerals like iron and other impurities give it different colors, such as yellow, orange, brown, green, and blue. Quartz granules have the sugary appearance and glassy luster.

Where Is Quartzite Natural Stone Found?

The formation of quartzite is mostly taken place during mountain construction events in the history of the planet earth. The occurrence of quartzite takes place at convergent plate boundaries where metamorphism process accomplished on sandstone rocks. Therefore, quartzite found in folded mountain ranges across the globe.

What Type of Rock Is Quartzite?

It is a metamorphic type of rock containing more than 70% sand & 90% silica in the equigranular type of formation. Quartzite is harder than a metal blade. Therefore, scratching is not easy on the surfaces of quartzite stones. It makes an ideal candidate for kitchen countertops and various external applications in residential as well as commercial projects. 

What Is the Difference Between Quartz and Quartzite?

Quartzite is a naturally formed natural stone and also terms as “Quartz arenite” in the modern geology. It is a metamorphic rock formed from the sandstone through recrystallization and granular process. It has mineral quartz granules in its formation. 

Quartz is an engineered or manufactured product with 93% mineral quartz (Silicon Dioxide) granules embedded into 7% resin and pigments. Quartz not only mimic the appearance of natural quartzite stones, but also gives similar properties such as durability, scratch resistance, water, heat, and cold resistance, and stain-resistant surfaces. 

However, uniqueness and natural beauty only found in natural quartzite stones where each piece is superb creation of Mother Nature.

Use of Quartzite Natural Stones

Despite superior strength, durability, and appearance, quartzite has limited consumption in the natural stone industry. Due to availability and processing expenses, it also a costly affair for large scale projects. However, recent improvements in quarrying technologies and cheaper shipment have made it standard natural stone category for all. Let’s see where natural quartzite stones used the most.

Architectural Application:

Quartzite, with some inclusions, become the pleasing colored stones useful for the gem and jewelry industry. For instance, fuchsite and muscovite inclusions in semitransparent to translucent quartzite give glittering luster famous as aventurescence (aventurine) due to flat flakes of mica. Therefore, you can create beads, cabochons, tumbled stones, and small ornaments or jewelry items from sorted quartzite. With some other inclusions, we can get blue, white, gray, orange, or yellow aventurine.

Stone Tool Applications of Quartzite:

Stone Tool

For thousands of years, quartzite is a favorite stone material to create various tools due to its strength and sturdy properties. We know Moh’s scale of quartzite is 7.0. It means it is stronger than modern steel blades and ancient granite tools.
Ancient civilizations created Arrowheads, knives, and various armors as well as day-to-day used tools. However, quartzite is not good material like obsidian to produce cutting tools. Instead, it is a better choice as crude cutting and chopping tools.

Conclusion:

We have seen that quartzite is a sturdy, durable, and appropriate choice of natural stones for exterior applications like a patio, swimming pool deck, porch, and walkways. It is a superior selection when you go for an external application with luxury and utility point of view.
