Qingshan Provincial Geopark in Jiaxiang County, with a total area of 2.43 km², is rich in geological relics. It is a small geopark mainly composed of typical Sanshanzi Formation stratigraphic profile, rich structural traces, spring landscape and cave type geological relics. In order to further promote the development of tourism and expand the landscape area of karst caves, the authors used comprehensive geophysical methods to look for hidden karst caves, and utilized microgravity survey methods to delineate three anomalies, all of which are of continuous low gravity characteristics. At the same time, the high-density resistivity method was used to verify the delineated anomalies. Finally, three karst caves with a certain scale were found, and good exploration results were achieved.
