Short summary
This study compares four regularization methods for deep seismic reflection data from the Jiangnan Orogenic Belt, South China. The optimal method regularizes and interpolates shot gathers at 100-meter intervals, improving signal-to-noise ratio and resolution, reducing artifacts, and yielding clearer seismic images. Results show data regularization is critical in deep seismic imaging for reliable geological interpretation and accurate mineral deposit detection.
