The accuracy of geophysical prospecting methods was limited. A combination of the audio magnetotelluric method and the nuclear magnetic resonance method was applied to aquifer division, enhancing the accuracy. Series of field tests for this method were carried out in an area of Bayanbaolige basin, Inner Mongolia, and the test results were compared with the hydrogeological profiles of the detailed hydrogeological survey for this tested area. The main conclusions were as follows: (1)The tested aquifer depth and thickness, within the depth of 100 m, were almost consistent with the hydrogeological profiles. (2)Based on this method, the decay times for mudstone, silty clay, silt, vesicular basalt and gravel were considered to be ≤30, 30-60, 60-120, 120-260 and 260-600 ms, respectively. This was highly consistent with the hydrogeological profiles. (3)The law of variation for aquifer water content was identical with that for water inflow represented in the hydrogeological profiles. Therefore, this method was feasible, and worthy to be promoted in production practices.
