Description To investigate the roles of crustal architectures playing in controlling the genesis and nature of supergiant Jiaodong orogenic gold system via seismic imaging, we deployed a NWW-SEE trending broadband seismic linear array (NCISP9) from September 2017 to September 2018 across SJZ (Sansandao-Jiaojia-Zhaoping), Qixia and Muping ore clusters in the Jiaodong gold province. These stations were equipped with Reftek-130 digitizers and seismometers of Guralp CMG3ESP-30s, CMG-3ESP60s, or CMG3T-120s. The array spanned two clusters of Jiaobei and Muping and was comprised of 20 stations with a total length of about 170 km. Field data sampling rate was 40 Hz. Rayleigh wave phase velocity dispersion curves were measured at periods of 1.0~25.0 s with an interval of 0.5 s from cross-correlations of vertical components of seismic noise data. These cross-correlations have separations longer than two wavelengths and signal-to-noise ratios of surface waves larger than five. A total of 190 high quality Rayleigh wave phase velocity dispersion curves are finally archived in the directories as:
(e.g., ./CDisper/CDisp.T.ZZ.CF.JD01-JD02.0.5-30s.350days.dat).

Type All the Rayleigh wave phase velocity dispersion curves were sorted in data format. The first two lines are longitudes and latitudes of source and receive stations, respectively. The following lines are Period, Phase-velocity, Standard error, N. Only when N=1, we have measurements.
