Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance. Minor amounts of former cementing materials, iron oxide, silica, carbonate and clay, often migrate during recrystallization, causing streaks and lenses to form within the quartzite. [ 1 ]
Natural stones like quartzite are more porous than engineered stone like quartz, which means they’re more susceptible to staining. Acidic substances like coffee, wine, and tomato sauce in ...
There is also a difference between quartz and quartzite, which may be confused because of the similarities in the name. Quartz countertops are man-made even though quartz is a natural material. Quartzite countertops on the other hand are natural and they are considered to be a high end countertop material. [7]

Quartzite offer a similar look as marble or granite, ranging from white to gray, with some shades of pink, red, yellow, or orange that may be present due to varying amount of iron oxide and other ...
Quartzite is sufficiently hard and dense that it is difficult to quarry. However, some quartzite is used as dimension stone, often as slabs for flooring, walls, or stairsteps. About 6% of crushed stone, used mostly for road aggregate, is quartzite. [4] Marble is also prized for building construction [48] and as a medium for sculpture. [6]
Cast stone can be made from white and/or grey cements, manufactured or natural sands, carefully selected crushed stone or well graded natural gravels and mineral coloring pigments to achieve the desired colour and appearance while maintaining durable physical properties which exceed most natural cut building stones.
The Zabriskie Quartzite is a Cambrian Period geologic formation of the northern Mojave Desert, in Inyo County, California and Nye County, Nevada. [ 1 ] [ 2 ] It is named for its occurrence at Zabriskie Point , located on the eastern slopes of Death Valley in Death Valley National Park .
