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.
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.

More about Soapstone and Diatomite
Here you can know more about Soapstone and Diatomite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Diatomite 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 Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Diatomite, 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, Diatomite is available in grey, white, yellow colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Diatomite is Soft. Properties of rock is another aspect for Soapstone vs Diatomite. Hardness of Soapstone and Diatomite is 1. The types of Soapstone are Metamorphic rock whereas types of Diatomite are Diatomite. 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 Diatomite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Diatomite is 0.90 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 Diatomite is heat resistant.
