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.

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
