Definition

Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation

Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Whiteschist and Quartzite Properties

Know all about Whiteschist and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Whiteschist and Quartzite belong to Metamorphic Rocks.Texture of Whiteschist is Foliated whereas that of Quartzite is Foliated, Granular. Whiteschist appears Banded and Foilated and Quartzite appears Lustrous. The luster of Whiteschist is subvitreous to dull while that of Quartzite is vitreous. Whiteschist is available in green, grey, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Whiteschist are creating artwork, gemstone, jewelry, production of lime and that 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.
