1) eclogite-facies metamorphism
榴辉岩相变质
1.
Previous studies on ultrahigh-pressure (UHP) metamorphic rocks in the northern Dabie indicated that the eclogites experienced granulite-facies retrogression after eclogite-facies metamorphism, and the obtained mineral Sm-Nd isochron ages therefore represented the time of granulite-facies retrogr ession.

榴辉岩相变质泥质岩
4) eclogite facies

华北古陆块北缘退变榴辉岩呈透镜状产于角闪岩相变质的早元古宙红旗营子群黑云斜长片麻岩中,岩相学研究显示它经历了峰期榴辉岩相、减压过程中的高压麻粒岩相和角闪岩相变质作用。
补充资料：榴辉岩
| 榴辉岩 eclogite 一种变质岩。由区域变质作用形成。主要由绿辉石和富镁的石榴子石组成。典型的榴辉岩不含斜长石，可含少量石英、蓝晶石、金红石、尖晶石等。具不等粒变晶结构及块状构造。有3种产出状态：①呈包裹体产于金伯利岩和层状超基性岩中。②呈夹层状、透镜体产于角闪岩相和麻粒岩相的岩石中。③呈夹层或透镜体产于蓝闪石-硬柱石片岩相岩石中。通常认为它是在极高压条件下形成的岩石，但温度变化范围较大。金伯利岩中的榴辉岩包体波认为是地幔物质的产物。 |
