Definition
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Soapstone and Eclogite
Here you can know more about Soapstone and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Eclogite 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 Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Eclogite, 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, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Soapstone vs Eclogite. The hardness of Soapstone is 1 and that of Eclogite is 3.5-4. The types of Soapstone are Metamorphic rock whereas types of Eclogite are Eclogite. 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 Eclogite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Eclogite is 0.75 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 Eclogite is heat resistant.
