All about Limestone and Evaporite Properties
Know all about Limestone and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone and Evaporite belong to Sedimentary Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Evaporite is Earthy. Limestone appears Rough and Banded and Evaporite appears Glassy, Vesicular and Foilated. The luster of Limestone is dull to pearly while that of Evaporite is subvitreous to dull. Limestone and Evaporite 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 Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
