Definition
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.

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.
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.

More about Soapstone and Luxullianite
Here you can know more about Soapstone and Luxullianite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Luxullianite 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 Luxullianite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Luxullianite, 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, Luxullianite is available in black, grey, orange, pink, white colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Luxullianite is Veined or Pebbled. Properties of rock is another aspect for Soapstone vs Luxullianite. The hardness of Soapstone is 1 and that of Luxullianite is 6-7. The types of Soapstone are Not Available whereas types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite. 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 Luxullianite is white. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Luxullianite is 0.79 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 Luxullianite is heat resistant, wear resistant.
