1 Definition
1.1 Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

5.1 Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
