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.

分布于超高压变质带北侧的柯石英榴辉岩经历了3个阶段的变质作用：(1)早期绿帘—角闪岩相阶段，以出现在石榴石和绿辉石中的包体矿物多硅白云母、石英、冰蓝闪石或青铝闪石、钠长石等为代表；(2)峰期柯石英榴辉岩相阶段，其矿物组合为Grt+Omp+Ky+Phe±Zo+Coe±Dia+Rt，其变质温度压力为800±50℃，≥28Kb；(3)退化变质作用阶段，早期为角闪岩相，以Amp+Pl+Di±Ep+Qtz+Tit等退变矿物组合为代表；晚期为绿片岩相，以绿帘石、绿泥石、黑云母、透闪石及钠长石等矿物为代表。
