Description The dataset was acquired by a dense array of 436 three‑component short‑period seismometers deployed in the Ordos Basin from 23 September to 28 December 2024. To investigate basin‑scale Vp/Vs structure, receiver functions (RFs) and coherent receiver functions (CRFs) were derived from teleseismic events with magnitude ≥ 5.0 and epicentral distances between 30° and 90°. Waveforms were rotated into radial, transverse and vertical components, windowed from 50 s before to 150 s after the theoretical P‑arrival, and band‑pass filtered between 0.1 and 1.0 Hz. RFs were computed by iterative time‑domain deconvolution of the vertical component from the radial and transverse components using a Gaussian low‑pass filter (width parameter = 5.0). CRFs were obtained through a Bayesian Markov‑Chain Monte Carlo (MCMC) inversion applied within overlapping subarrays of five stations. For each subarray, the inversion was parallelized over 200 CPUs, each running 15,000 MCMC iterations. The first 5,000 iterations were used for model burn‑in; thereafter every 10th iteration of the final 10,000 was retained. The best‑fitting model from the posterior distribution was used to generate the final CRF estimates.
