| 英文摘要 | The Poisson's ratio, an important parameter to understand the interior of the earth, can be dertermined from the ratio of P- to S- seismic wave velocity. Teleseismic P waveform contains much information about the Ps converted wave and its multiples from discontinuities in the crust and the mantle, which can be used to acquire the average thickness and the Poisson' s ratio of the crust by the H-k stacking method. Data from 68 broadband seismic stations located in the northwestern basin-mountain boundary of the Bohai Bay Basin are processed, and the distributions of the average crustal thickness and Poisson 7 s ratios are determined. We find that there is a distinct differentiation of Poisson' s ratios in the study area. The distribution of Poisson' s ratios on the flank of the mountain is rather uniform, while on the flank of the basin much variable. The comparison between Poisson's ratios and the surface geology manifests that there is an apparent response in the lower crust to the intense extension of the Bohai Bay Basin during Cenozoic. The Poisson' s ratios deduced from seismology can be used to constrain the compostion of the crust in the study area. |
