Formation
Sovites are formed due to low degrees of partial melting of rocks.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

All about Sovite and Chert Properties
Know all about Sovite and Chert properties here. All properties of rocks are important as they define the type of rock and its application. Sovite belongs to Igneous Rocks while Chert belongs to Sedimentary Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Chert is Banded, Rough. Sovite appears Dull, Banded and Foilated and Chert appears Glassy or Pearly. The luster of Sovite is subvitreous to dull while that of Chert is waxy and dull. Sovite is available in black, brown, colourless, green, grey, pink, white colors whereas Chert is available in black, brown, green, grey, red, white 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 Chert are creating artwork, gemstone, in fire-starting tools, jewelry, to ignite fire, used in flintlock firearms.
