1.1 Definition

Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows

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

All about Ignimbrite and Limestone Properties

Know all about Ignimbrite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Ignimbrite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Ignimbrite is Aphanitic whereas that of Limestone is Clastic or Non-Clastic. Ignimbrite appears Dull, Vesicular and Foilated and Limestone appears Rough and Banded. The luster of Ignimbrite is vitreous to dull while that of Limestone is dull to pearly. Ignimbrite is available in beige, black, brown, 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 Ignimbrite are cemetery markers, commemorative tablets, creating artwork 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.
