Metamorphic Rocks

Information about Quartzite

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Quartzite Uses. We have provided you with all information about Quartzite rock here. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite is white. Get to know more about Quartzite rock and characteristics of Quartzite rock in the next sections.
