Definition

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

All about Limestone and Boninite Properties

Know all about Limestone and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Limestone belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Limestone is Clastic or Non-Clastic whereas that of Boninite is Aphanitic to Porphyritic. Limestone appears Rough and Banded and Boninite appears Dull and Soft. The luster of Limestone is dull to pearly while that of Boninite is vitreous. 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 Boninite is available in bluish - grey, brown, green, 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 Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
