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

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