Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
