Formation
Sovites are formed due to low degrees of partial melting of rocks.
  
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

All about Sovite and Rhyolite Properties
Know all about Sovite and Rhyolite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Rhyolite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Rhyolite is Aphanitic, Glassy, Porphyritic. Sovite appears Dull, Banded and Foilated and Rhyolite appears Banded. The luster of Sovite is subvitreous to dull while that of Rhyolite is earthy. Sovite is available in black, brown, colourless, green, grey, pink, white colors whereas Rhyolite is available in grey, white, light black 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 Rhyolite are gemstone, laboratory bench tops, jewelry.
