Abstract：Geophysical exploration technology is one of the essential technical means of hydrogeological in-vestigation and plays an irreplaceable role in obtaining geological information,such as stratigraphic struc-ture and geological structure.In general,the magmatic rock area has poor water richness,so it is necessa-ry to adopt more reasonable geophysical exploration technology to complete the underground water source exploration.In this paper In this paper,a combined geophysical exploration model utilizing microtremor methods and Controlled Source Audio Magnetotellurics(CSAMT)is employed to investigate the granite formations within the study area,allowing for the acquisition of seismic wave velocity and resistivity pa-rameters.The practice has proved that the two approaches are effective in interpreting stratigraphic struc-ture and water-bearing structure and have better complementarity in geological interpretation.Based on the results of the geophysical interpretation,hydrological analysis revealed a high-quality water source with a single well yielding up to 291.54 m3/d within the study area.,which not only solved the actual wa-ter demand of the local area,but also provided a certain reference for groundwater exploration in this kind of area in the future.
