Formation

Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
