摘　　要：自大陆地壳中发现柯石英和金刚石以来,大陆深俯冲研究一直是固体地球科学研究的前沿和热点领域之一。大陆俯冲带超高压变质岩的发现,掀起了板块构造理论的一场革命,促进了大陆动力学研究。近三十年来,大陆深俯冲研究在大陆地壳的俯冲深度、大陆碰撞带的p-T-t演化、大陆碰撞过程中的流体体制、大陆碰撞带深部的元素活动性、同位素定年和示踪俯冲带变质作用、超高压变质岩地质测温、俯冲隧道内部板片-地幔相互作用、大陆地壳深俯冲和折返的驱动力等方面都取得了许多重要成果。这些研究成果极大丰富了大陆动力学的内涵,发展了板块构造理论,深化了对地球内部层圈运作机制的理解。本文着重选取近三十年来大陆深俯冲研究取得的经典成果和最新进展进行评述,对存在的重要科学问题和研究方向也提出了建议。The study of continental deep subduction has been the forefront and the hotspot of solid earth sciences since findings of coesite and diamond in metamorphic rocks of supracrustal origin. Identification of ultrahigh-pres- sure （UHP） metamorphic rocks in continental subduction zones led to the revolution of the plate tectonic theory, remarkably promoting the study of continental geodynamics. In the past three decades, the study of continental deep subduction has made great achievements, especially on the depth of continental subduction, p-T-t path recon- struction during continental subduction and exhumation, fluid regime and element mobility during continental colli- sion, geochronology and isotope tracing in continental subduction zones, geothermometry of UHP rocks, slab-man- tle interaction in continental subduction channels, and driving force for continental deep subduction and exhuma- tion. Such achievements have greatly expanded the research areas of continental geodynamics, developed the plate tectonics theory, and deepened the understanding of the operation of Earth＇s interior. In this paper, we have re-viewed the studies of continental deep subduetion and UHP metamorphism in the past classic studies and the newest, exciting developments. We have also raised important tinental deep subduction, and given possible perspectives on future studies.
