Based on the experience of exploration of geothermal deposits, performed with high efficiency, it is possible to show the sequence of application of electrical exploration methods of magnetotelluric and audiomagnetotelluric sounding.
The first stage is AMT and MT sounding along the regional profile. As a result, a geoelectric section is constructed, reflecting the presence of an anomalously low-resistivity horizon in the depth interval from 0 to 500 m.
At the second stage, AMT and MT soundings are carried out in the areal version, due to which maps of the total longitudinal conductivity are constructed with the identification of anomalous areas.
At the third stage, anomalous areas are detailed and a field model is built with recommendations for drilling.
