| 摘 要： | 本文主要从三个方面反映１９８７年以来国内外变质地质学研究的新进展：（１）变质Ｐ－Ｔ－ｔ轨迹与区域岩石学研究；（２）变质流体与岩石的相互作用；（３）高压、超高压变质。变质ｐ－Ｔ－ｔ轨迹按地壳拉张区、地壳增厚区、俯冲带和麻粒岩相变质地区等不同构造环境予以论列；变质流体岩石的相互关系是按区域变质、接触变质和麻粒岩相变质地区等三个类型对比描述。高压、超高压变质研究近年来得到快速发展，也提出了许多问题。本文主要介绍柯石英榴辉岩岩石学和榴辉岩相岩石学的主要问题。

| Abstract: | The paper gives a thorough review of the new advances in metamorphic geologymade since 1987.The major topics are:1)metamorphic p-T-t path and regional study;2) the interaction between metamorphic fluids and rocks;3)the petrology of high and uLtra-high pressure metamorphism. The contents of metamorphic p-T-t path are discussedusing a tectonic setting framework of 1)the region of crustal extension;2)the region ofcrustal thickening;3)the subduction zone and 4)the granulite facies metamorphic terrain. Metamorphic fluid-rock interactions are discussed in terms of regional,contact andgranulite facies metamorphism in that order. The current boom in the study of high andultra-high pressure metamorphism offers many challenges to all geological disciplines.This paper concentrates on the petrology of coesite eclogite and the prospects for research in high pressure and ultra-high pressure metamorphism. |
