利用宽频带流动台站(YSBSN)记录的远震波形数据和远震接收函数方法,反演了黄海东、西两侧地壳上地幔的S波速度结构.结果表明,莫霍面深度在30～38 km之间变化,位于中方一侧的JNN台下方地壳厚度最大,可以归因于华北板块和扬子板块的碰撞;韩方一侧的地壳厚度自北向南逐渐变厚,但仍然难以厘定朝鲜半岛南部潜在碰撞带的位置,这些问题的解决需要更大范围的流动台站观测.由于部分台站位于巨厚的沉积层和多孔的火山岩之上,与浅部构造的相关性使得接收函数表现出较大振幅的混响,从而影响了来自深部结构的转换震相.
The S-wave velocities of the crust and upper mantle in the east and west sides of the Huanghai Sea were retrieved using teleseismic waveform data and teleseismic receiver function recorded by a broadband mobile station (YSBSN). The results show that the depth of the Moho is between 30 ~ 38 km. The crust thickness below the JNN station on the Chinese side is the largest, which can be attributed to the collision between the North China Plate and the Yangtze Plate. The crust thickness on the South side gradually becomes thicker from north to south, but it is still difficult to determine the North Korean Peninsula The solution of these problems requires a wider range of mobile station observations due to the location of the potential collision zones in the southern part of the country.The correlation with the shallow structure allows the receiver function to be characterized by the fact that some of the stations are located above the thick sediments and porous volcanic rocks The larger amplitude of the reverberation, which affects the transition phase from the deep structure.
