Formation
Sovites are formed due to low degrees of partial melting of rocks.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Sovite and Comendite Properties
Know all about Sovite and Comendite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Comendite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Comendite is Porphyritic. Sovite appears Dull, Banded and Foilated and Comendite appears Foliated. The luster of Sovite is subvitreous to dull while that of Comendite is dull. Sovite is available in black, brown, colourless, green, grey, pink, white colors whereas Comendite is available in blue, bluish - grey 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 Comendite are cemetery markers.
