1 Definition

1.1 Definition

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

Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished

5 Formation

5.1 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.

The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

All about Tachylite and Appinite Properties

Know all about Tachylite and Appinite properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite and Appinite belong to Igneous Rocks.Texture of Tachylite is Vitreous whereas that of Appinite is Porphyritic. Tachylite appears Glassy and Appinite appears Dull, Banded and Foilated. The luster of Tachylite is resinous while that of Appinite is subvitreous to dull. Tachylite is available in black, dark brown colors whereas Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. The commercial uses of Tachylite are cemetery markers, creating artwork and that of Appinite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner.
