Definition
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

Skarn vs Suevite 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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Skarn and Properties of Suevite. Learn more about Skarn vs Suevite in the next section. The interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Skarn and Suevite, they have various applications in construction industry. The uses of Skarn in construction industry 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 and that of Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Skarn and Suevite
Here you can know more about Skarn and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Skarn and Suevite consists of mineral content and compound content. The mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Metamorphic Rocks. When we have to compare Skarn vs Suevite, 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, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Skarn is Dull and that of Suevite is Banded. Properties of rock is another aspect for Skarn vs Suevite. The hardness of Skarn is 6.5 and that of Suevite is 5.5. The types of Skarn are Endoskarns whereas types of Suevite are Phyllosilicates, Calcite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Skarn and Suevite is light to dark brown. The specific heat capacity of Skarn is 0.92 kJ/Kg K and that of Suevite 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.Skarn is heat resistant whereas Suevite is heat resistant.
