| 英文摘要 | We probe lowermost mantle seismic anisotropy beneath Southeast Asia based on S and ScS differential splitting measurements of the broadband teleseismic data recorded by the Chinese Digital Seismic Network (CDSN) and the International Federation of Digital Seismograph Networks (FDSN). Twenty-four pairs of high-quality S and ScS shear wave splitting parameters from 7 deep events (>400 km) are obtained. Splitting parameters of S phases agree well with previous work, indicating upper mantle anisotropy beneath seismic stations. After correction for the upper mantle anisotropy and further analysis of the splitting parameters, we obtain 24 reliable ScS residual splitting parameters. Our results show Null splitting in the area between 107 degrees-112 degrees while non-Null splitting dominating to the east and west. Our results suggest that the distributions of splitting parameters indicate regional variation of the lowermost mantle anisotropy, which may be related with stagnant ancient Tethys and/or Pacific plates. |
