5 Formation

5.1 Formation

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.

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
