All about Laterite and Limestone Properties

Know all about Laterite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Laterite and Limestone belong to Sedimentary Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Limestone is Clastic or Non-Clastic. Laterite appears Rough and Banded and Limestone appears Rough and Banded. The luster of Laterite is dull while that of Limestone is dull to pearly. Laterite is available in brown, buff, red colors whereas Limestone is 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 Laterite are an oil and gas reservoir, source of bauxite, used in aquariums and that 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.
