宁夏银川基准台下方地壳厚度研究

The Analysis on Moho Depth beneath Ningxia Yinchuan Station

    摘要
  • 摘要: 提取宁夏银川台远震P波接收函数,计算了台站下方地壳厚度和波速比,得出银川台下方地壳厚度为48.0 km,体波波速比为1.72。分析认为银川台下方地壳分层结构明显,地壳厚度起伏剧烈,具有较明显的各向异性特征。

     

    Abstract: The teleseismic receiver functions of Ningxia Yinchuan seismic station are calculated with two different Gauss filter factors using H-Kappa stacking method. The results show that the Moho depth beneath the seismic station is 48.0 km and Vp to Vs ratio in there is 1.72. Carring out more analysis, we found the crust in the studied area has complex stratification structures with obvious anisotropic characteristic and crust thickness changes dramatically.
