The coesite-diamond-bearing eclogite distributed in the northern part of the UHPM belt suffered three stages of metamorphism. The first stage is the Ep amphibolite facies metamorphism, which is represented by the paragenesis of phe+Qtz+Cro/Bar Bar+Ep+Ab occurred as inclusions in Grt and Omp; The second stage is the peak metamorphism of eclogite facies with mineral assembledge of Grt+Omp+Coe±Dia±Ky±Zo±Phe+Rt. The P -T condition is 800±50℃,≥28Kb; The third stage is the amphibolite facies retrograded metamorphism from the peak one, which can be divided intothe early amphibolite facies stage with the mineral assembledge of Amp+ Pl+Di+Qtz±Ep+Ilm/Ttn and the late greenschist facies one with the mineral assembledge of Ep+Chl+Bi+Tr+Ab.
