Definition
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Formation
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.
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.

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