Archaeological Significance
Formation
Pyrolite 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.
Sovites are formed due to low degrees of partial melting of rocks.

All about Pyrolite and Sovite Properties
Know all about Pyrolite and Sovite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite and Sovite belong to Igneous Rocks.Texture of Pyrolite is Phaneritic whereas that of Sovite is Granular, Poikiloblastic. Pyrolite appears Rough and Shiny and Sovite appears Dull, Banded and Foilated. The luster of Pyrolite is shiny while that of Sovite is subvitreous to dull. Pyrolite is available in dark greenish - grey colors whereas Sovite is available in black, brown, green, grey, pink, white colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds 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).
