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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

More about Pantellerite and Pumice
Here you can know more about Pantellerite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Pumice consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Pantellerite vs Pumice, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Pantellerite is Layered and Foliated and that of Pumice is Vesicular. Properties of rock is another aspect for Pantellerite vs Pumice. The hardness of Pantellerite is 6-7 and that of Pumice is 6. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Pantellerite is Not Available and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
