Formation

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

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
