Formation

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