Formation
Formation
Ijolite 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 Ijolite and Sovite Properties
Know all about Ijolite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Ijolite and Sovite belong to Igneous Rocks.Texture of Ijolite is Earthy, Granular whereas that of Sovite is Granular, Poikiloblastic. Ijolite appears Banded and Foilated and Sovite appears Dull, Banded and Foilated. The luster of Ijolite is greasy to dull while that of Sovite is subvitreous to dull. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Ijolite are cemetery markers, creating artwork 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).
