Formation
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

All about Limestone and Marl Properties
Know all about Limestone and Marl properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Marl belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Marl is Earthy. Limestone appears Rough and Banded and Marl appears Rough and Dull. The luster of Limestone is dull to pearly while that of Marl is dull. Limestone and Marl 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 Marl are creating artwork, soil conditioner.
