1.1 Definition

Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

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

5 Formation

5.1 Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

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.
