Definition

Ijolite is an intrusive igneous rock which is composed mainly of nepheline and an alkali pyroxene, usually aegirine-augite

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

Formation

Ijolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Ijolite and Limestone Properties

Know all about Ijolite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Ijolite belongs to Igneous Rocks while Limestone belongs to Sedimentary Rocks.Texture of Ijolite is Earthy, Granular whereas that of Limestone is Clastic or Non-Clastic. Ijolite appears Banded and Foilated and Limestone appears Rough and Banded. The luster of Ijolite is greasy to dull while that of Limestone is dull to pearly. Ijolite 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 Ijolite are cemetery markers, 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.
