Formation

Picrite 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.

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

All about Picrite and Sovite Properties

Know all about Picrite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Picrite and Sovite belong to Igneous Rocks.Texture of Picrite is Earthy, Rough whereas that of Sovite is Granular, Poikiloblastic. Picrite appears Rough and Shiny and Sovite appears Dull, Banded and Foilated. The luster of Picrite and Sovite is subvitreous to dull. Picrite and Sovite are available in black, brown, green, grey, pink, white, yellow colors. The commercial uses of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo) 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).
