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

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.

Latite 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 Tachylite and Latite Properties

Know all about Tachylite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite and Latite belong to Igneous Rocks.Texture of Tachylite is Vitreous whereas that of Latite is Aphanitic to Porphyritic. Tachylite appears Glassy and Latite appears Rough. The luster of Tachylite is resinous while that of Latite is subvitreous to dull. Tachylite is available in black, dark brown colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Tachylite are cemetery markers, creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
