中文摘要：

化学地球动力学是地球化学与地球动力学之间的交叉学科，是二十世纪末期地幔地球化学研究的热点和前沿。随着人们对板片-地幔相互作用机制及其地球化学效应的认识，化学地球动力学研究已经从地幔不均一性本身拓展到具体俯冲板片对地幔成分的影响。这个拓展为我们认识地球内部的运作机制、俯冲带壳幔相互作用和地幔不均一性的尺度等重要科学问题做出了重大贡献。本文系统回顾了大洋玄武岩成因与地壳物质再循环、大洋玄武岩源区的岩石学性质、板块俯冲与大洋玄武岩成因、大陆镁铁质超镁铁质岩成因和板片-地幔相互作用以及花岗岩成因与大陆动力学等方面的突出进展，对化学地球动力学领域存在的重要科学问题和今后的研究方向也提出了建议。

英文摘要：

Chemical geodynamics, the hotspot and the forefront of mantle geochemistry in the past decade, is an in- terdiscipline subject of geochemistry and geodynamics. With advances in understanding the mechanism of slab-man- tle interaction and its geochemical effects, the study of chemical geodynamics has been extended from the mantle heterogeneity itself to the geochemical effects of subducted slabs on the mantle composition. Such an extension has contributed greatly to our understanding of many important issues in solid earth chemistry, especially the operation of Earth＇s interior, the slab-mantle interaction in subduction zones, and the spatial-temporal scale of mantle heter- ogeneity. In this paper, we have systematically reviewed remarkable progresses in the following issues., the origin of oceanic basalts and the recycling of crustal materials, the petrology of mantle sources for oceanic basalts, the slab-mantle interaction and its bearing on the origin of oceanic basalts and continental mafic-ultramafic rocks, and granite petrogenesis and continental dynamics. We have also raised important questions in the study of chemical ge- odynamics, and presented our personal perspectives on future studies.
