5 Formation
5.1 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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Soapstone vs Skarn Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Soapstone and Skarn Reserves. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Soapstone vs Skarn information and Soapstone vs Skarn characteristics in the upcoming sections.

Soapstone vs Skarn Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Soapstone vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Soapstone and Properties of Skarn. Learn more about Soapstone vs Skarn in the next section. The interior uses of Soapstone include Bathrooms, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Soapstone and Skarn, they have various applications in construction industry. The uses of Soapstone in construction industry include Manufacture of magnesium and dolomite refractories and that of Skarn include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Gold and silver production, Manufacture of magnesium and dolomite refractories.

More about Soapstone and Skarn

Here you can know more about Soapstone and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Soapstone and Skarn 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 Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Metamorphic Rocks. When we have to compare Soapstone vs Skarn, 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, Skarn is available in black, brown, colourless, green, grey, white colors. Appearance of Soapstone is Dull, Banded and Foilated and that of Skarn is Dull. Properties of rock is another aspect for Soapstone vs Skarn. The hardness of Soapstone is 1 and that of Skarn is 6.5. The types of Soapstone are Not Available whereas types of Skarn are Endoskarns. 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 Skarn is light to dark brown. The specific heat capacity of Soapstone is 0.88 kJ/Kg K and that of Skarn is 0.92 kJ/Kg K.
