Abstract:Through the method of keywords co-occurrence analysis, we carry out an analysis of the development and application status of deep seismic sounding (DSS) technology in China. The results show that the data processing of deep seismic sounding is mainly based on the forward modeling method of 2D dynamic ray tracing, while the 3D crustal model is mainly constructed by Kriging interpolation. DSS method can reveal the seismogenic tectonic, but rarely summarizes the relationship between the regional crustal structure and earthquake distribution and activities. In terms of seismic sounding results, including the type of crustal structure and crustal thickness, are closely related to the formation of geothermal, metal, and oil and gas mineral resources. However, there are no available DSS database or data products for mineral resources exploration. Ocean deep exploration has become a focused area in the application of DSS method. The onshore and offshore deep seismic experiment should be strengthened to give full play to the advantages of the two different observation modes.
