1.1 Definition

Anorthosite is a granular igneous rock composed largely of labradorite or plagioclase

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

5 Formation

5.1 Formation

Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

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.
