Аннотация: The results of interpreting magnetotelluric soundings performed in the Southern Ladoga region arepresented. When performing 3D inversion, both new data obtained by the LADOGA working group in 2018–2021 and data from the 1-EV profile (the “Loop” segment) worked out in the early 2000s were used. Basedon the results of automatic inversion carried out in the ModEM program (Egbert and Kelbert), a 3D geoelectric model of the Earth’s crust to a depth of 60 km has been constructed, which shows the complex inhomogeneous structure of the studied territory. Two anomalous zones of crustal electrical conductivity oriented SE and NE are distinguished in the geoelectric model; the first one is a continuation of the well-known Ladoga anomaly. The presence of the second conductive structure confirms the results of the single magnetovariational soundings performed by I.I. Rokityansky in the different segments of the East European Platform in the early 1980s.
