岩石圈结构与大陆动力学

LITHOSPHERIC STRUCTURE AND CONTINENTAL GEODYNAMICS

对 1999年 7月第 2 2届IUGG大会以后的 4年期内 ,中国地球物理研究在岩石圈结构和大陆动力学方面的主要进展作了简要评述 .这些研究进展主要表现在以下几个方面 :区域性岩石圈物性结构的研究 ,利用深地震测深剖面对地壳、上地幔速度结构的勘查 ,利用GPS观测研究大陆内部的现今运动和变形 ,青藏高原动力学研究 ,大别—苏鲁超高压变质带的地球物理勘查及动力学机理研究 ,沉积盆地的地球物理勘查及演化过程研究 ,以及板块动力学研究 ,等等 .

This paper briefly reviews main progress in the research on lithospheric structure and continental geodynamics made by Chinese geophysicists during last 4 years since 22nd IUGG General Assembly in July 1999. The research mainly covers the following fields: investigations on regional lithospheric structure, DSS survey of crust and upper mantle velocity structure, study on present day inner movement and deformation of China continent by analyzing GPS observations, geodynamics of Qingzang (Tibetan) plateau, geophysical survey of the Dabie mountain and Jiangsu Shandong border ultra high pressure metamorphic belt and probing into its formation mechanism, geophysical observations in sedimentary basins and study on their evolution process, and plate dynamics, etc.
