摘要
Based on the data of a dense linear array of a passive seismic experiment crossing the Longmenshan Fault in the east margin of Qinghai-Tibet Plateau, the authors measured the splitting parameters of Moho-converted Ps phases (Pms) for 147 teleseismic events recorded by 28 stations, and then analyzed the crustal anisotropy of this strong basin-range interaction zone. The results demonstrate that the crustal anisotropy of study area has significantly different characteristics in different subregions. The azimuthal variation of FPD in different blocks indicates that the crustal deformation is accommodated or controlled by the major boundary faults between the blocks.
