Definition
Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Archaeological Significance
Formation
Sovites are formed due to low degrees of partial melting of rocks.
Tachylite 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 Tachylite Properties
Know all about Sovite and Tachylite properties here. All properties of rocks are important as they define the type of rock and its application. Sovite and Tachylite belong to Igneous Rocks.Texture of Sovite is Granular, Poikiloblastic whereas that of Tachylite is Vitreous. Sovite appears Dull, Banded and Foilated and Tachylite appears Glassy. The luster of Sovite is subvitreous to dull while that of Tachylite is resinous. Sovite is available in black, brown, green, grey, pink, white colors whereas Tachylite is available in black, dark 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 Tachylite are cemetery markers, creating artwork.
