Definition

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

Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
