5 Formation

5.1 Formation

Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

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