Definition

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Formation

Pyrolite 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.
