Abstract

The present study firstly analyzed surface waveform fittings for 8 wave paths crossing through four different regions of the Chinese mainland (eastern,central,northern and western China), and then inverted for ID pathaveraged S-velocities for such paths. The inverted crustal and upper-mantle Svelocities showed obvious region-related features, which are well consistent with known geotectonic units and previous research results. Such analyses showed that surface waveform modeling is a reliable method to get crustal and upper-mantle velocity structure. Furthermore, this method has a prominent advantage in detection upper-mantle structure compared with fundamental-mode surface-wave dispersion method.
