Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone

All about Limestone and Granite Properties
Know all about Limestone and Granite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Granite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Granite is Granular, Phaneritic. Limestone appears Rough and Banded and Granite appears Veined or Pebbled. The luster of Limestone is dull to pearly while that of Granite is dull to grainy with sporadic parts pearly and vitreous. 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 Granite 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 Granite are curling, gemstone, laboratory bench tops, tombstones, used in aquariums.
