5.1 Formation

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

Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
