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.

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