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.
  
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Soapstone and Teschenite
Here you can know more about Soapstone and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Teschenite 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 Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Soapstone vs Teschenite. The hardness of Soapstone is 1 and that of Teschenite is 7. The types of Soapstone are Not Available whereas types of Teschenite are Not Available.
