The traditional H-κ method using grid search and RF stacking developed by Zhu and Kanamori (2000) has been applied for calculating H and κ of the crust globally. Accurate crustal thickness (H) and average crustal Vp/Vs ratio (κ) are essential for understanding the tectonic setting and other fundamental geological questions. However, the traditional H-κ method may provide some questionable results in regions where crustal structures are complex and uncertain, like crustal anisotropy and dipping crust. Recently, H-κ method with harmonic corrections, which corrects both Ps and crustal multiples by including crustal azimuthal anisotropy and dipping interfaces for multiple layers, was developed by Jiangtao Li, Xiaodong Song, and Pan Wang at the University of Illinois. We apply this new method to the dense Hi-CLIMB seismic array in western-central Tibetan Plateau, which covered Yarlung-Zangpo Suture (YZS) and Bangong-Nujiang Suture (BNS) linearly along approximately 85°E. With the improved H value, we can better interpret both past and present tectonic settings of the region, as improved κ value can offer better constraints for mineral composition and melting condition of the crust.","abstract_html":"Receiver function(RF) is commonly used for analyzing seismic waves generated at structural boundaries and imaging major interfaces of the Earth.
