Definition

Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation

Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

All about Carbonatite and Soapstone Properties

Know all about Carbonatite and Soapstone properties here. All properties of rocks are important as they define the type of rock and its application. Carbonatite belongs to Igneous Rocks while Soapstone belongs to Metamorphic Rocks.Texture of Carbonatite is Granular, Poikiloblastic whereas that of Soapstone is Polished. Carbonatite appears Dull, Banded and Foilated and Soapstone appears Dull, Banded and Foilated. The luster of Carbonatite is subvitreous to dull while that of Soapstone is greasy. Carbonatite is available in black, brown, green, grey, pink, white colors whereas Soapstone is available in black, black to grey, green, grey colors. The commercial uses of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux and that of Soapstone are cemetery markers, creating artwork, gemstone, jewelry, manufacture of soap, solvents, dyes, plastics and fibres, production of lime, source of magnesia (mgo).
