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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Soapstone vs Dolomite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Soapstone vs Dolomite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Soapstone and Properties of Dolomite. Learn more about Soapstone vs Dolomite in the next section. The interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Soapstone and Dolomite, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Dolomite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
More about Soapstone and Dolomite
Here you can know more about Soapstone and Dolomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Dolomite 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 Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Dolomite, 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, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Soapstone vs Dolomite. The hardness of Soapstone is 1 and that of Dolomite is 3.5-4. The types of Soapstone are Not Available whereas types of Dolomite are Boninite and Jasperoid. 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 Dolomite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Dolomite is 0.92 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 Dolomite is heat resistant, pressure resistant, wear resistant.
