接收函数方法研究进展
|
摘要
远震P波波形数据中包含了大量的地震台站下方地壳和上地幔速度间断面所产生的PS转换波及其多次反射波的信息,由此提取的接收函数是了解地壳上地幔速度精细结构的重要步骤之一。本文介绍了目前在提高接收函数结果的稳定性和精度方面的研究进展,包括石油勘探中一些成熟的地震反射处理方法逐步渗透到接收函数的研究领域。这些处理方法以前所未有的分辨率展示了地壳上地幔结构的横向非均匀性。
The data of teleseismic P waveform include a lot of informations of P-S converted wave and P multiple reflection wave produced by the interface of crust and mantle underneath the stations. The receiver function obtained from the waveforms offers an approach to understanding of the crust and mantle fine velocity structures. In this paper, the new progress in increasing the stability and precision of the receiver function is introduced. Many mature methods in oil exploration have been lead into the receiver function research field. Application of all these methods shows the inhomogeneity of crust and upper mantle with high resolution.
