Definition

Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains

Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

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.

Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
