The gold deposit in Jiuzhanggou area, Songxian County, Henan Province is a tectonic altered rock type deposit. With the continuous exploitation of the mine in recent years, the amount of resources has gradually decreased. Deep and edge prospecting is an important exploration direction at present. The near north-south trending fault structure F1 is the main ore-bearing (ore-controlling) structure in the mining area. Along the F1 of the ore-bearing (ore-controlling) structure, there is still a possibility of large-scale mineralization in the deep part. The detection depth of traditional geophysical prospecting method is limited, and the conventional large depth detection method is restricted by various factors in the study area to varying degrees, which makes it difficult to carry out deep exploration. The microtremor exploration method collects the natural source surface wave information and uses its dispersion characteristics to invert and calculate the S-wave velocity structure of the underground medium, and infers the underground geological structure and structure to achieve the purpose of exploration. It has the characteristics of high resolution, large detection depth, no electromagnetic background interference, high efficiency and low cost, and provides technical support for deep exploration in the study area. In order to explore the geological structure and metallogenic potential of the deep and edge of the research region, the microtremor exploration test was carried out at the location of the previous geophysical profile, and the apparent S-wave velocity structure below 2.5 km of the profile was obtained. There are obvious low-velocity anomalies and velocity differences on the two-dimensional micro-motion S-wave velocity section. Combined with the previous geological and geophysical survey data, the fracture morphology of the inland graben boundary, the deep extension characteristics of the ore-bearing fracture structure F1 and the intrusion range of the rock mass are inferred. The results are in good agreement with the previous geophysical profile results and the known geological profile, indicating that the micro-motion exploration can provide important geophysical information for the deep and edge prospecting work in the research region, which is of great guiding significance for the realization of the prospecting breakthrough of alternative resources.
