Ambient-noise cross-correlation data for imaging the Lianhuashan Fault Zone, South China

This dataset supports the manuscript “Inherited upper-crustal architecture controls the structural localization of the Lianhuashan W–Sn metallogenic system.” It contains 7,684 vertical-component ambient-noise cross-correlation functions obtained from two temporary dense linear seismic arrays across the Lianhuashan Fault Zone in South China. The dataset includes 5,460 cross-correlation functions for the JX1 array and 2,224 for the JX2 array, together with the station identifiers and geographic coordinates used in the analysis. The cross-correlation functions are provided in SAC format. Continuous records were divided into 12-hour windows with a 2-hour overlap, demeaned, detrended, band-pass filtered between 0.05 and 5 Hz, spectrally whitened, normalized, and combined using phase-weighted stacking. These data support the double-beamforming analysis, Rayleigh-wave dispersion measurements, and shear-wave velocity inversions reported in the associated study.
