Abstract: The deficiency of drinking water is a common problem in mountain areas of China. It is urgent to solve the problem of serious water shortages in arid areas. Based on the 1∶50 000 hydrogeological map, the fractured water storage structures were found in the studied area. The water target area for the Zhaolaoyuan village was determined from three aspects: water supply spaces, watersheds and runoff channels. Based on the EH4 profiles, seven polarized sounding points and two symmetrical quadrupole sounding points were obtained by the EH4 and symmetric quadrupole excitation polarization. By analyzing the EH4 continuous conductance speed profiles and the measured depth curves, locations of the mining wells were determined, which can be used as an example of efficiently finding groundwater in water scarcity mountain areas. This joint technology has advantages of reducing the interpreted solutions of geophysical data and the exploration cost and risks. The interpreted results show that the groundwater storage zones are intrusive rocks and the surrounding rock alteration zones and the fault structured zones. The results may provide technical references for locating groundwater in magmatic rock areas of serious water scarcity.
