【摘要】 简要总结了近年在欧亚大陆发现的超高压变质岩地质产状、岩石类型、结晶条件和构造位置等基本特征，对超高压变质作用及其地球动力学机制的研究现状及存在的问题进行了评述。基于对大别－苏鲁超高压变质带的研究成果，认为超高压变质作用可能是一种新型的区域变质作用，而目前所建立的任何一种地球动力学模型都不完善。建议今后在岩石学和矿物学研究基础上，加强对超高压变质杂岩的地球化学、构造地质学、实验岩石学及地球物理学等方面的研究。更多还原

【Abstract】 The general features of ultrahigh-pressure metamorphic rocks discovered recentlyfrom Eurasian continent, including occurrence, rock type, crystalline condition and tec-tonic location, are summarized briefly and the progresses and problems of ultrahigh-pres-sure metamorphism and geodynamics are reviewed in this paper.According to the charac-teristics of protolith of eclogites,the discovery of the different types of non-mafic ultra-high-pressure metamorphic rocks and the correlation of both P-T condition and age be-tween retrograde metamorphism of eclogites and regional metamorphism of country rocksin the Dabie-Sulu district, ultrahigh-pressure metamorphism is considered to be a newtype of regional metamorphism. The sequence of high-pressure metamorphic belt in theDabie Mountains and the occurrence of coesite-bearing granulite retrograded from eclogitein eastern Shangdong suggest that the satisfactory geodynamic model for ultrahigh-pres-sure metamorphism has not been established up to now. On the basis of petrological andmineralogical works , the authors emphasize that geochemical,tectonic,experimentalpetrological and geophysical studies of ultrahigh-pressure metamorphic coniplex should bestrengthened in the future.更多还原
