本文介绍了利用宽频带瑞雷波和勒夫波频散对欧亚大陆的地壳和上地幔进行层析成像系统研究的结果。多数周期的分辨率为 5°～ 7 5°。解释结果表明 ,塔里木盆地、四川盆地以及西藏高原的地壳显示低速异常 ;以乌拉尔山脉为界的东欧地台和西伯利亚地盾之下有延伸到上地幔的大陆根
This paper presents the results of a systematic study of the tomography of the crust and upper mantle in Eurasia using broadband Rayleigh and Loeff-wave dispersion. Most of the cycle of the resolution of 5 ° ~ 7 5 °. Interpretation results show that the crust in the Tarim Basin, the Sichuan Basin and the Tibet Plateau show low-velocity anomalies. The eastern continental platform bounded by the Ural Mountains and the continental root extending to the upper mantle below the Siberian Shield
