| Abstract: | We have inverted Rayleigh wave dispersion data to produce a high resolution image of the S-wave velocity structure of the lithosphere beneath northeast boundary region of the North China Craton and adjacent areas.Based on waveform data recorded from 60 stations and 11 events,Rayleigh wave phase velocities were measured at periods from 25 to 150 s.The phase velocities were utilized in subsequent inversion to solve for the S-wave velocity structure from 40 km down to 300 km depth.The result shows strong later... |
