Skarn and Sovite
Definition
Definition
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Sovites are formed due to low degrees of partial melting of rocks.

All about Skarn and Sovite Properties
Know all about Skarn and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Skarn belongs to Metamorphic Rocks while Sovite belongs to Igneous Rocks.Texture of Skarn is Earthy, Mud-rich, Rough whereas that of Sovite is Granular, Poikiloblastic. Skarn appears Dull and Sovite appears Dull, Banded and Foilated. The luster of Skarn is waxy and dull while that of Sovite is subvitreous to dull. Skarn is available in black, brown, colourless, green, grey, white colors whereas Sovite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Skarn are creating artwork, gemstone, jewelry, metallurgical flux, 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).
