Formation
Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Sovites are formed due to low degrees of partial melting of rocks.

All about Diabase and Sovite Properties
Know all about Diabase and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Diabase and Sovite belong to Igneous Rocks.Texture of Diabase is Aphanitic, Granular whereas that of Sovite is Granular, Poikiloblastic. Diabase appears Vesicular and Sovite appears Dull, Banded and Foilated. The luster of Diabase is not available while that of Sovite is subvitreous to dull. Diabase is available in dark grey to black colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Diabase are an oil and gas reservoir, cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones 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).
