Jadeitite and Mylonite


Mylonite and Jadeitite


Definition

Definition
Jadeitite is a metamorphic rock usually found in blueschist grade metamorphic terrains   
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Formation

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.   
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
