Definition
Definition
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Limestone and Lherzolite Properties
Know all about Limestone and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Lherzolite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Lherzolite is Grenue. Limestone appears Rough and Banded and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Limestone is dull to pearly while that of Lherzolite is subvitreous to dull. 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 Lherzolite is available in black, dark greenish - grey, green, pink, purple 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 Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
