Definition
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar
Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

All about Minette and Limestone Properties
Know all about Minette and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Minette belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Minette is Porphyritic whereas that of Limestone is Clastic or Non-Clastic. Minette appears Dull, Banded and Foilated and Limestone appears Rough and Banded. The luster of Minette is subvitreous to dull while that of Limestone is dull to pearly. Minette is available in black, bluish - grey, brown, dark greenish - grey, 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 Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, 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.
