1.1 Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

5.1 Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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.
