Definition
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

Features
Available in lots of colors, Generally rough to touch, Is one of the oldest rock
Available in Lots of Colors and Patterns, Clasts are smooth to touch, Splintery, Very fine grained rock
Archaeological Significance
Formation
Sovites are formed due to low degrees of partial melting of rocks.
Felsite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Sovite and Felsite Properties
Know all about Sovite and Felsite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Felsite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Felsite is Arborescent Patterned, Vitreous. Sovite appears Dull, Banded and Foilated and Felsite appears Layered, Banded, Veined and Shiny. The luster of Sovite is subvitreous to dull while that of Felsite is vitreous. Sovite is available in black, brown, green, grey, pink, white colors whereas Felsite is available in black, blue, brown, green, orange, red, tan, yellow 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 Felsite are mirror, jewelry.
