Formation
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.
Sovites are formed due to low degrees of partial melting of rocks.

All about Blueschist and Sovite Properties
Know all about Blueschist and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Blueschist belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Blueschist is Foliated whereas that of Sovite is Granular, Poikiloblastic. Blueschist appears Dull and Banded and Sovite appears Dull, Banded and Foilated. The luster of Blueschist is dull while that of Sovite is subvitreous to dull. Blueschist is available in blue, bluish - grey, purple, shades of blue colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Blueschist are cemetery markers, commemorative tablets, creating artwork, curling, 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).
