Definition
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation
Monzonite 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.
