Аннотация:RussianIn May 2019, along a line in the area of the village of Aleksandrovka (Kaluga Region), a integrated electrical exploration was performed, which included the method of audiomagnetotelluric sounding (AMT), the resistivity method, and the method of induced polarization (IP). The resistivity method is performed in the modification of vertical electrical sounding (VES) and electrical tomography (ET). The paper presents the methodological features of data analysis and interpretation. A comparison of the results of time and frequency IP measurements was done. The results of the interpretation of the data of AMTZ VES and ET were compared. A joint inversion of AMT-ET-VP data was performed.
