Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
From Pantelleria, a volcanic island in the Strait of Sicily
Fine Grained Rock, Opaque Rock
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.
