Abstract: A geochemical study of elemental migration from granulite-facies rocks to amphibolite-facies rocks during retrograde metamorphism has been carried out through the analyses both of petrochemical data for whole rocks and electronic microprobe data for essential minerals(e．g．hypersthene，augite andhornblende)in the rocks．The removal variations of compositions for major elements in the whole rocks and their essential minerals are similar，which suggests that such changes were most likely controlled by the transformation of main mineralogical phases and the fluid／rock interaction during the retrograde metamorphism．Abundances of K，Rb，Cs，Fe3+ ，Ti，LREE of whole rocks are gradualy increased from Tongde granulites to biotite-hornblende plagiogneisses，while abundances of Li，Ca，Mg，Fe2+，V，Co，Pb，P and HREE decreased In addition，the elements such as Na, Be, Rb, Y, Nb, Ta, Th, U, Cr, Ni，REE are increased from Shaba granulites to epidote-hornblende plagiogneisses，while Li，K，Ti，Fe，Mn，Mg，V，Co，Zn，Pb decreased ． Many lithophile elements and LREE are enriched and some transitional elements are depleted in the highly retrograded rocks from granulites，therefore the authors suppose that the metamorphic fluids in the retrograde metamorphic process could be derived from upper-crust reservoirs．Due to the fluid／rock interaction many chemical elements in granulites including REE were activated and migrated in the prolonged duration of retrograde metamorphism．
