摘要
对区内高压超高压榴辉岩的分布、分类,岩石、矿物特征,变质作用特征进行了系统研究。查明了榴辉岩产出和分布规律,在此基础上划分了榴辉岩相、退变质过程的变质矿物世代和变质作用演化阶段,并对榴辉岩的成因进行了探讨。认为高压绿帘～蓝片岩相、高压榴辉岩相、超高压榴辉岩相是在同一俯冲带内不同深度发生的同期变质作用产物。
This paper deals with high -and ultrahigh -pressureeclogite, its occurrence, classification, petrology and mineral features and metamorphism. The eclogite phases, retrograde metamorphic minerals and metamorphic stages have been discussed. The authors consider that high - pressure epidote - blueschist, high - pressure eclogite, and ultrahigh -pressure eclogite formed at the same time, but at different depths.
