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

A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

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.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Tachylite and Evaporite Properties

Know all about Tachylite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite belongs to Igneous Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Tachylite is Vitreous whereas that of Evaporite is Earthy. Tachylite appears Glassy and Evaporite appears Glassy, Vesicular and Foilated. The luster of Tachylite is resinous while that of Evaporite is subvitreous to dull. Tachylite is available in black, dark brown colors whereas Evaporite is available in colourless, green, grey, silver, white colors. The commercial uses of Tachylite are cemetery markers, creating artwork and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
