5.1 Formation

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

All about Limestone and Pumice Properties

Know all about Limestone and Pumice properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Pumice belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Pumice is Vesicular. Limestone appears Rough and Banded and Pumice appears Vesicular. The luster of Limestone is dull to pearly while that of Pumice is earthy. 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 Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey 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 Pumice are as a traction material on snow-covered roads, as an abrasive in pencil erasers, fine abrasive used for polishing, manufacture of soap, solvents, dyes, plastics and fibres, used in aquariums.
