Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
