Definition

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

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

All about Boninite and Limestone Properties

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