| 摘 要： | 榴辉岩作为板块边缘俯冲带中的高压变质岩石，现常以不同的产状零星出露。关于其呈面状暴露的机制，目前流行有三种模式。即造山楔模式、双轨模式和变质核杂岩模式。通过研究榴辉岩区的岩石组合和岩石的Ｐ－Ｔ－ｔ轨迹，可以了解区域构造及其演化背景。本文综述了研究进展，并以胶南一苏北一大别山榴辉岩带为例说明。

| Abstract: | Eclogites now distribute scatteredly in different attitudes along the orogene,acted as character-istic rocks in the high pressure subdutional metamorphic belt during the geological history stages. Concerningthe plane exhumation of them,many models were proposed :orogenic wedge,double paths,metamorphic corecomplex models. Having studied the petrology assemblagte of eclogite-cropped regions,the P-T-t paths of therocks, people get to understand their evolution and background of tectonics. Here illustrate the reaserch ad-vances in Jiaonan-Subei-Dabie eclogite belt. |
