同时,根据特征变质矿物的出现及镁在石榴石-黑云母矿物对的分配与温度的关系计算,变质温度为550700℃,压力为400800MPa,相当于中压角闪岩相。
According to the appearence of characteristic metamorphic mineral and the relation of distribution of Mg in garnet-biotite to temperature , the metamorphic temperature is about 550 & 700 ℃ , the pressure is about 400-800 MPa .

该高压变质带以发育大量的高压脉为特征。高压脉与其他脉体相比,具有特征的高压变质矿物组合,包括石榴子石、绿辉石、多硅白云母、黝帘石等。
This high-pressure metamorphic belt is characterized by the assemblages of high-pressure metamorphic minerals , comparing with other veins , it composed garnet , omphacite , phengite , zoisite and so on .
