【摘要】 利用上海地震台阵16个台站记录的远震资料,采用接收函数线性反演方法,对台阵下的地壳速度结构进行研究,获得了研究区域内地壳厚度和地壳速度的分布特征。研究结果表明,研究区域Moho面深度约为33±2 km,Moho面深度基本不变,地幔顶部S波速度约4.4 km/s,地壳内没有发现明显的低速层。更多还原

【Abstract】 We selected broadband teleseismic waveform data recorded by the Shanghai seismic array to study the crustal thickness and structure in Shanghai region by modeling the teleseismic P wave receiver function.The results show that beneath the studied area, the depth of Moho discontinuity is about 33±2 km, without obvious variation.S wave velocity gets up to 4.4 km/s at the depth of Moho discontinuity.There is no obviously low velocity layer in the crust.更多还原
