Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
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
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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.

Whiteschist 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. Whiteschist vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Skarn. Learn more about Whiteschist vs Skarn in the next section. The interior uses of Whiteschist 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 Whiteschist and Skarn, they have various applications in construction industry. The uses of Whiteschist in construction industry include 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 Whiteschist and Skarn
Here you can know more about Whiteschist and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Skarn consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Whiteschist vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Skarn is available in black, brown, colourless, green, grey, white colors. Appearance of Whiteschist is Banded and Foilated and that of Skarn is Dull. Properties of rock is another aspect for Whiteschist vs Skarn. The hardness of Whiteschist is 1.5 and that of Skarn is 6.5. The types of Whiteschist 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 Whiteschist is white while that of Skarn is light to dark brown. The specific heat capacity of Whiteschist is 0.92 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.Whiteschist is heat resistant whereas Skarn is heat resistant.
