Formation

Formation
Lherzolite 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.   
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
