| 摘 要： | 本文简述了国际上超高压变质岩研究领域中十年来的主要进展。含柯石英变沉积岩的发现暗示了上地壳物质可被迅速带至地下９０ｋｍ或更深处经受超高压变质作用，并在八千万年中很快折返出露地表。这一研究在实验岩石学、造岩矿物学、同位素年代学和大陆造山带的地球动力学等四个方面给固体地球科学领域带来了一系列重大突破。预计在今后五至十年内，这一研究将保持其热点地位，并围绕超高压变质作用过程和超高压变质岩折返的动力学过程展开工作。

| Abstract: | The paper reviews international developments in ultra-high-pressure metamorphism(UHPM ) in the last decade. Coesite bearing metasedimentary rocks were formed at depth of at least 90km, then exhumed during a short span of 80 Ma. The research on UHPM has caused much breakthrough in experimental petrology, rock-forming mineralogy, isotope chronology and orogenic geodynamics. It is believed that the UHPM will continue being a hot focus in the next decade. Future research will cover details of UHPM process and geodynamics behind the exhumation of UHPM rocks. |
