Advances in Teleseismic Body-wave Imaging of Intracrustal Interface Structures
摘要
Abstract
Fine-scale intracrustal interface structures record regional tectonic deformation and evolutionary history and constitute critical constraints for seismic hazard assessment and mineral resource exploration.In recent years,teleseismic body-wave imaging has advanced substantially,transcending their limitations in mantle and bulk crust studies to reveal,with unprecedented precision,multiscale crustal interfaces from sedimentary layers to the Moho.Here,we review the latest research progress in teleseismic body-wave imaging of crustal interfaces from two perspectives,teleseismic converted-and reflected-wave imaging,focusing on receiver function and teleseismic virtual-source reflection techniques.For receiver functions,we emphasize methodological advances and applications in imaging shallow crustal structures while examining current trends such as dense array deployments,migration imaging,and multi-method joint inversions.We discuss the fundamental principles and field applications of teleseismic virtual source reflection imaging using four key techniques:deconvolution,autocorrelation,cross-correlation,and reverse-time migration.Finally,we summarize the current research status and emerging trends in the teleseismic imaging of intracrustal interfaces and discuss future directions.关键词
