Formation
Larvikite 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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
