5.1 Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
