Definition
Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

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

All about Tachylite and Limestone Properties
Know all about Tachylite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Tachylite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Tachylite is Vitreous whereas that of Limestone is Clastic or Non-Clastic. Tachylite appears Glassy and Limestone appears Rough and Banded. The luster of Tachylite is resinous while that of Limestone is dull to pearly. Tachylite is available in black, dark brown colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses of Tachylite are cemetery markers, creating artwork and that 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.
