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