Formation

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.

Earth movements can cause rocks to be either deeply buried or squeezed and hence the rocks are heated and put under great pressure.
