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

More about Pumice and Pantellerite
Here you can know more about Pumice and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pumice and Pantellerite consists of mineral content and compound content. The mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Pumice vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Pumice is Vesicular and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Pumice vs Pantellerite. The hardness of Pumice is 6 and that of Pantellerite is 6-7. The types of Pumice are Scoria whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pumice is white, greenish white or grey while that of Pantellerite is .
