Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Trachyandesite 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 Trachyandesite Properties
Know all about Limestone and Trachyandesite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Trachyandesite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Trachyandesite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Limestone appears Rough and Banded and Trachyandesite appears Dull and Soft. The luster of Limestone is dull to pearly while that of Trachyandesite is earthy. 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 Trachyandesite is available in black, brown, light to dark grey 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 Trachyandesite are creating artwork, pottery.
