Definition
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic
  
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

All about Phonolite and Limestone Properties
Know all about Phonolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Phonolite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Phonolite is Granular whereas that of Limestone is Clastic or Non-Clastic. Phonolite appears Banded and Foilated and Limestone appears Rough and Banded. The luster of Phonolite is greasy to dull while that of Limestone is dull to pearly. Phonolite is available in brown, buff, cream, green, grey, pink, white 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 Phonolite 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.
