Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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 Scoria and Pantellerite
Here you can know more about Scoria and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Pantellerite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, 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 Scoria vs Pantellerite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Pantellerite is available in dark greenish - grey colors. Appearance of Scoria is Glassy and Vesicular and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Scoria vs Pantellerite. The hardness of Scoria is 5-6 and that of Pantellerite is 6-7. The types of Scoria are Basaltic Scoria and Andesitic 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 Scoria is white while that of Pantellerite is .
