Formation

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

Sovites are formed due to low degrees of partial melting of rocks.

All about Quartzite and Sovite Properties

Know all about Quartzite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Sovite is Granular, Poikiloblastic. Quartzite appears Lustrous and Sovite appears Dull, Banded and Foilated. The luster of Quartzite is vitreous while that of Sovite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Sovite is available in black, brown, green, grey, pink, 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 Sovite are an oil and gas reservoir, as a feed additive for livestock, creating artwork, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
