Definition
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

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.

More about Soapstone and Oolite
Here you can know more about Soapstone and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Oolite consists of mineral content and compound content. The mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. 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. Appearance of Soapstone is Dull, Banded and Foilated and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Soapstone vs Oolite. The hardness of Soapstone is 1 and that of Oolite is 3-4. The types of Soapstone are Metamorphic rock whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Soapstone is black while that of Oolite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Oolite is 0.65 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Soapstone is heat resistant, pressure resistant whereas Oolite is heat resistant, wear resistant.
