地球内部结构探测研究——以华北克拉通为例

Deep Earth exploration——A case study from the North China Craton

本文立足对地球物理学科发展态势的分析认识,通过解剖华北克拉通研究实例,对地球内部结构探测研究,特别对壳幔结构的地震学探测研究,对中国近20多年的发展做了回顾;探讨了从区域问题认识全球构造的研究思路.

This paper reviewed the progresses in studying the Earth＇s deep interior already made in China during the past 20 years, with the North China Craton as an example. Particular descriptions were given on the seismologically retrieved crustal and mantle structures of the region. From a systematic geodynamic perspective, the linkage between local and global tectonics and therefore the possibility of understanding the geodynamic evolution of the Earth as a whole on the basis of regional behaviors were further discussed.
