| 摘 要： | 上地幔过渡带的结构形态对于研究上覆岩石圈的构造环境有十分重要的意义。本文通过对横跨华北克拉通中东部的一条北西向的测线L上分布的35个宽频带台站记录的远震数据进行接收函数的计算和共转换点叠加成像,得到了测线下方上地幔过渡带的结构。成像结果表明：华北克拉通的三个陆块处于不同的构造环境,西部陆块较为稳定,中部造山带位于地幔对...

| Abstract: | It is very important to study the structure of upper mantle transition zone to understand the tectonic environment of the lithosphere above.In this paper,we calculate the P receiver functions from the teleseismic events recorded by 35 stations in a line across the North China Craton(NCC),and then mapping the upper mantle structure from the method of common conversion points.The result shows that:the three blocks of the North China Craton stay in different tectonic environment,the western block stay in a sta... |
