Definition

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

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Quartzite and Serpentinite Properties

Know all about Quartzite and Serpentinite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite and Serpentinite belong to Metamorphic Rocks.Texture of Quartzite is Foliated, Granular whereas that of Serpentinite is Earthy. Quartzite appears Lustrous and Serpentinite appears Rough and Dull. The luster of Quartzite is vitreous while that of Serpentinite is waxy and dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Serpentinite is available in black, brown, 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 Serpentinite are commemorative tablets, creating artwork.
