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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Soapstone and Oolite Properties
Know all about Soapstone and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Soapstone belongs to Metamorphic Rocks while Oolite belongs to Sedimentary Rocks.Texture of Soapstone is Polished whereas that of Oolite is Clastic or Non-Clastic. Soapstone appears Dull, Banded and Foilated and Oolite appears Rounded and Rough. The luster of Soapstone is greasy while that of Oolite is pearly to shiny. Soapstone is available in black, black to grey, green, grey colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow 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 Oolite are creating artwork, jewelry, used in aquariums.
