Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.
Felsite 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 Pantellerite and Felsite
Here you can know more about Pantellerite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pantellerite and Felsite consists of mineral content and compound content. The mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all . When we have to compare Pantellerite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Pantellerite is available in dark greenish - grey colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Pantellerite is Layered and Foliated and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Pantellerite vs Felsite. The hardness of Pantellerite is 6-7 and that of Felsite is 5-5.5. The types of Pantellerite are Pantelleritic Ignimbrite whereas types of Felsite are Not Available. 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 Felsite is white.
