基于接收函数方位变化的青藏高原地壳各向异性研究进展
Review on crustal anisotropy investigations beneath the Qinghai-Xizang Plateau based on azimuthal variations of receiver functions
摘要
Abstract
Seismic anisotropy provides key information about the past and present deformations of the crust and mantle below and is crucial for understanding the interior structure of the Earth and deep dynamic processes.Receiver function is a frequently used method with high lateral resolution to detect velocity discontinuity,composi-tion and anisotropy.In recent years,investigating crustal azimuthal anisotropy based on the azimuthal variations of receiver functions has been widely applied to the study of the uplift and expansion mechanisms of the Qinghai-Xi-zang Plateau.This paper first briefly introduces several main models regarding the uplift and expansion of the Qinghai-Xizang Plateau,the formation mechanisms of seismic anisotropy,and the methods for analyzing crustal anisotropy using receiver functions.Then the recent advances in studying crustal anisotropy of the Qinghai-Xizang Plateau based on the azimuthal variations of receiver functions are introduced in detail.Finally,based on the cur-rent research status,this paper briefly summarizes the challenges and conclusions.Although the formation mecha-nisms of the observed crustal anisotropy remain controversial,these studies provide important observational con-straints on the crustal anisotropy characteristics of the Qinghai-Xizang Plateau and significant implications into its uplift and expansion mechanisms.Based on the high lateral resolution of the receiver function method and an in-creasing number of dense seismic array observations,it is expected that more details of crustal deformation will be observed in the future,which will play a significant role in the study of deep dynamic processes.关键词
