Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Borolanite and Limestone Properties
Know all about Borolanite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Borolanite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Borolanite is Granular whereas that of Limestone is Clastic or Non-Clastic. Borolanite appears Banded and Foilated and Limestone appears Rough and Banded. The luster of Borolanite is greasy to dull while that of Limestone is dull to pearly. Borolanite is available in brown, buff, cream, green, grey, pink, white 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 Borolanite are cemetery markers 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.
