Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
  
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
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
  
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.

Pantellerite 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. Pantellerite vs Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Skarn. Learn more about Pantellerite vs Skarn in the next section. The interior uses of Pantellerite include Not yet used whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Pantellerite and Skarn, they have various applications in construction industry. The uses of Pantellerite in construction industry include Na 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 Pantellerite and Skarn
Here you can know more about Pantellerite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Skarn consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Skarn, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Skarn is available in black, brown, colourless, green, grey, white colors. Appearance of Pantellerite is Layered and Foliated and that of Skarn is Dull. Properties of rock is another aspect for Pantellerite vs Skarn. The hardness of Pantellerite is 6-7 and that of Skarn is 6.5. The types of Pantellerite are Pantelleritic Ignimbrite 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 Pantellerite is unknown while that of Skarn is light to dark brown. The specific heat capacity of Pantellerite is Not Available 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.Pantellerite is heat resistant whereas Skarn is heat resistant.
