Formation

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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
