Based on the continuous seismic ambient noise data from 48 stations in Wuhan-Ezhou-Huanggang-Huangshi (WEHH) metropolitan area and adjacent regions, we use ambient noise tomography method to obtain Rayleigh-wave phase velocity structure at periods of 5 s to 40 s. The results show that phase velocity structure of the upper to middle crust is closely correlated with regional tectonic units. The low-velocity anomalies are observed along the eastern margin of Jianghan basin and the southern margin of Dabie mountain, whereas the Dabie orogen is marked by high-velocity anomalies. In the middle to lower crust, the Moho topography influences the phase velocity structure, with a crust-penetrating low-velocity anomaly near the Wulongquan fault, suggesting a potential pathway for deep material upwelling. The Dabie orogen retains high-velocity anomalies associated with its metamorphic basement. At greater depths, from the lower crust to the uppermost mantle, widespread low-velocity anomalies are observed, which may be attributed to lithospheric delamination or mantle-derived material upwelling. The low-velocity anomalies on both sides of Yangtze river are closely linked to the formation of middle-lower Yangtze metallogenic belt, reflecting a spatiotemporal coupling between deep geodynamic processes and shallow mineralization. This study has higher resolution than previous imaging results, which can provide more reliable insights for revealing the deep geodynamic mechanisms of regional tectonic evolution and mineralization.
