5 Formation
5.1 Formation
Porphyry is formed in two stages: the magma cools slowly deep within the crust or the magma is cools rapidly as it erupts from a volcano, creating small grains that are usually invisible to naked eye.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
