Definition

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Sovite is a coarse-grained variety of carbonatite which belongs to intrusive igneous rock

Formation

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.

Sovites are formed due to low degrees of partial melting of rocks.

All about Tachylite and Sovite Properties

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