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.

Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
