Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

All about Limestone and Charnockite Properties
Know all about Limestone and Charnockite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Charnockite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Charnockite is Granular. Limestone appears Rough and Banded and Charnockite appears Veined or Pebbled. The luster of Limestone is dull to pearly while that of Charnockite is not available. 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 Charnockite is available in black, grey, orange, pink, 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 Charnockite are curling, gemstone, laboratory bench tops, tombstones.
