1.1 Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

5.1 Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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.
