Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Limestone and Granulite Properties
Know all about Limestone and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Granulite is Granoblastic. Limestone appears Rough and Banded and Granulite appears Veined or Pebbled. The luster of Limestone is dull to pearly while that of Granulite is vitreous. Limestone and Granulite are 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 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
