Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

All about Limestone and Trachyte Properties
Know all about Limestone and Trachyte properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Trachyte belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Trachyte is Aphanitic to Porphyritic. Limestone appears Rough and Banded and Trachyte appears Banded. The luster of Limestone is dull to pearly while that of Trachyte is metallic. 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 Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white 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 Trachyte are cemetery markers, creating artwork.
