Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Pantellerite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pantellerite and Properties of Serpentinite. Learn more about Pantellerite vs Serpentinite in the next section. The interior uses of Pantellerite include whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Pantellerite and Serpentinite, they have various applications in construction industry. The uses of Pantellerite in construction industry include and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Pantellerite and Serpentinite
Here you can know more about Pantellerite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Serpentinite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Pantellerite is Layered and Foliated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Pantellerite vs Serpentinite. The hardness of Pantellerite is 6-7 and that of Serpentinite is 3-5. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pantellerite is while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
