Keywords:Garnet aggregation, Fluid infiltration , Ti-mobility, HP metamorphism

Garnet and rutile, providing useful information on P-T condition, fluid history as well as timing of metamorphism, are common minerals in eclogite. Although, behaviour of Ti, Nb, and Ta eclogite facies is well understood, the relationship between mobility of Ti and garnet texture is poorly studied. Therefore, garnet aggregates and Ti-bearing minerals will be discussed the Khungui eclogite in the Zavkhan terrane of western Mongolia.
