| 摘 要： | 利用宁夏区域数字地震台网记录到的远震提取接收函数,用H-Kappa叠加方法反演得到宁夏区域数字地震台网子台下方的地壳厚度和波速比。结果显示,宁夏地区地壳平均厚度约为46km,并且由西南向东北逐渐减薄,南北两端地壳厚度差异达15km,东西两端地壳厚度差异达8km。泊松比计算结果显示,宁夏北部和中南部的泊松比值较高,中北部泊松比值较低。

| Abstract: | Receiver functions were calculated by using teleseismic records of Ningxia Digital Seismic Network,and crustal thickness in Ningxia area is obtained by stacking receiver functions with H-Kappa technique.The results reveal that the average crustal thickness in Ningxia is about 46 km,and the crust becomes thinner from Southwest to Northeast.The crust in the South is 15 km thicker than that in the North,while the one in the West is 8 km thicker than that in the East.The Poisson ratio in the North and the middl... |
