Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Quartzite and Cataclasite Properties
Know all about Quartzite and Cataclasite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite and Cataclasite belong to Metamorphic Rocks.Texture of Quartzite is Foliated, Granular whereas that of Cataclasite is Clastic. Quartzite appears Lustrous and Cataclasite appears Dull and Banded. The luster of Quartzite and Cataclasite is vitreous. Quartzite and Cataclasite are available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums and that of Cataclasite are commemorative tablets, creating artwork.
