Formation

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

Schist 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 Sovite and Schist Properties

Know all about Sovite and Schist properties here. All properties of rocks are important as they define the type of rock and its application. Sovite belongs to Igneous Rocks while Schist belongs to Metamorphic Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Schist is Foliated, Platy. Sovite appears Dull, Banded and Foilated and Schist appears Layered and Shiny. The luster of Sovite is subvitreous to dull while that of Schist is shiny. Sovite is available in black, brown, green, grey, pink, white colors whereas Schist is available in black, blue, brown, dark brown, green, grey, silver colors. The commercial uses 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) and that of Schist are used in aquariums, writing slates.
