The data include the cross-correlation function extracted from the continuous seismic background noise data of vertical component recorded by 54 fixed seismic stations and 17 mobile seismic stations in Jiuyishan and its adjacent area from May 2016 to June 2017, and the final inversion of crustal S-wave velocity. The dispersion curves of group velocity and phase velocity of 2-40s are obtained by time-frequency analysis. The inversion imaging results show that the structural characteristics of the crust and upper mantle of the Yangtze block and the Cathaysian Block are significantly different. The S-wave velocity distribution map of 10-20km shows linear and continuous low velocity anomalies, which may be the specific boundary between the Yangtze block and the Cathaysian Block. The imaging results provide seismological constraints for understanding the tectonic evolution history of South China. The uploaded data provide valuable data and information for others to further study the structural characteristics of Jiuyi mountain and its adjacent areas.
