榴辉岩相(eclogite facies)是一个高压(P>1GPa)变质相,以典型岩石榴辉岩(eclogite)而得名。进一步划分高压和超高压榴辉岩相,或以温度高低划分为低温、中温、高温榴辉岩相。 典型的榴辉岩的矿物组合为镁铝石榴石+绿辉石。呈块状构造,不等粒变晶结构。
根据熔浆-矿物平衡热力学,岩浆被认为起源于榴辉岩相条件下俯冲板片的部分熔融。
Based on the melt-mineral equilibrium thermodynamics, it is believed that the adakitic magma originated by partial .
研究结果表明:各类榴辉岩相岩石的流体包裹体均程度不同地发生了次生变化。未发现原生包裹体。
The studied results show that different secondary changes occurred in fluid inclusions of various rocks and no primary inclusion has been found.
因此,岩浆起源于加厚地壳底部榴辉岩相镁铁质岩石的低度部分熔融,且岩浆源区受到了流体的影响。
Therefore, the magmas were the product of low partial melting of mafic eclogite at the base of the thickened crust, and their magma sources were affected by fluids.
