Abstract：In view of the stratigraphic characteristics of the pediment hilly area of the Luliang Mountains, the authors conducted a selective study of the CSAMT data collection frequency, carried out comparative test and application based on the results of groundwater and geothermal exploration and, as a result, achieved satisfactory geological effects. Tests show that, for the relatively deeply buried but not very thick strata, the encryption of the data acquisition frequency density can improve the resolution capability and detect all significant small anomalies; Especially in the case that the exploration data are deep groundwater aquifers and thin layers, the application of high-density frequency to conducting data acquisition can increase the quantity of investigated information and achieve good geological results.
