1 Definition

1.1 Definition

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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

5.1 Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

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 Limestone and Tachylite Properties

Know all about Limestone and Tachylite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Tachylite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Tachylite is Vitreous. Limestone appears Rough and Banded and Tachylite appears Glassy. The luster of Limestone is dull to pearly while that of Tachylite is resinous. Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors whereas Tachylite is available in black, dark brown colors. The commercial uses of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper and that of Tachylite are cemetery markers, creating artwork.
