Formation

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

Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

All about Sovite and Tuff Properties

Know all about Sovite and Tuff properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Tuff belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Tuff is Clastic, Pyroclastic. Sovite appears Dull, Banded and Foilated and Tuff appears Dull, Vesicular and Foilated. The luster of Sovite is subvitreous to dull while that of Tuff is vitreous to dull. Sovite is available in black, brown, green, grey, pink, white colors whereas Tuff is available in brown, grey, yellow colors. The commercial uses of Sovite and Tuff 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).
