Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

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.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
