Sovite and Hornfels
Definition
Definition
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

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

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