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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Soapstone and Andesite
Here you can know more about Soapstone and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Andesite is Dull and Soft. Properties of rock is another aspect for Soapstone vs Andesite. The hardness of Soapstone is 1 and that of Andesite is 7. The types of Soapstone are Not Available whereas types of Andesite are Icelandite. 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 Andesite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
