Formation
Sovites are formed due to low degrees of partial melting of rocks.
Tephrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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