利用S KS波分裂研究上地幔各向异性及其在中国东部的应用
Study on Upper Mantle Anisotropy Using SKS Wave Splitting and Its Application in Eastern China
摘要
Abstract
Seismic anisotropy is one of the most direct and valid ways to study mantle flow and lithospheric deformation.Using teleseismic events to identify SKS phases,which travel along an almost perpendicular ray path,can directly reveal the upper mantle anisotropy beneath receiver stations.In recent years,the SKS wave splitting measurement has gradually become a useful tool to investigate continental dynamics and its evolution,as well as the characteristics of the mantle deformation,since this measurement is sensitive to azimuthal anisotropy and characterized by low ambiguity.In the present study,we assemble the SKS wave splitting results in Eastern China of the last 20 years and discuss their evolution in Eastern China and their deficiencies and problems to be solved.This high-quality and high-density seismic network includes 102 broadband tempora-ry stations located in the middle-lower Yangtze River and 262 permanent stations in the same re-gion operated by China National Digital Seismograph Network.Our results refine the deformation characteristics of the upper mantle anisotropy.关键词
