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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

More about Pantellerite and Andesite
Here you can know more about Pantellerite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Andesite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Andesite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Pantellerite is Layered and Foliated and that of Andesite is Dull and Soft. Properties of rock is another aspect for Pantellerite vs Andesite. The hardness of Pantellerite is 6-7 and that of Andesite is 7. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Andesite are Icelandite. 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 Andesite is white. The specific heat capacity of Pantellerite is 0.84 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
