5 Formation
5.1 Formation
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 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.

Skarn vs Soapstone 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 Skarn and Soapstone Reserves. Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. 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 Skarn vs Soapstone information and Skarn vs Soapstone characteristics in the upcoming sections.

Skarn vs Soapstone 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. Skarn vs Soapstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Soapstone. Learn more about Skarn vs Soapstone in the next section.

More about Skarn and Soapstone

Here you can know more about Skarn and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Soapstone consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite 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 Skarn vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Skarn is available in black, brown, colourless, green, grey, white colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Skarn is Dull and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Skarn vs Soapstone. The hardness of Skarn is 6.5 and that of Soapstone is 1. The types of Skarn are Endoskarns whereas types of Soapstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn is light to dark brown while that of Soapstone is black. The specific heat capacity of Skarn is 0.92 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.Skarn is heat resistant whereas Soapstone is heat resistant, pressure resistant.
