Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

More about Metapelite and Soapstone
Here you can know more about Metapelite and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Soapstone consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Metapelite is Banded and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Metapelite vs Soapstone. The hardness of Metapelite is 5-6 and that of Soapstone is 1. The types of Metapelite are Metamorphic rock whereas types of Soapstone are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Soapstone is black. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Soapstone is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Metapelite is heat resistant, impact resistant, pressure resistant whereas Soapstone is heat resistant, pressure resistant.
