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
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

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.

Metapelite 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. Metapelite vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Skarn. Learn more about Metapelite vs Skarn in the next section. The interior uses of Metapelite include Decorative aggregates and Interior decoration whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Metapelite and Skarn, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate 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 Metapelite and Skarn
Here you can know more about Metapelite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Skarn consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, 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 Metapelite vs Skarn, 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, Skarn is available in black, brown, colourless, green, grey, white colors. Appearance of Metapelite is Banded and that of Skarn is Dull. Properties of rock is another aspect for Metapelite vs Skarn. The hardness of Metapelite is 5-6 and that of Skarn is 6.5. The types of Metapelite 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 Metapelite is unknown while that of Skarn is light to dark brown. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Skarn is 0.92 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 Skarn is heat resistant.
