Simultaneous magnetotelluric and magnetovariation soundings carried out recently at the western slope of the Voronezh Massif in
the network of the international project KIROVOGRAD outlined bright quasi-linear conductivity anomalies in the lower
crust, having a complex junction southwards from Briansk. The nature of these anomalies is clarified in the correlation study
of electromagnetic (primarily, horizontal magnetovariation) responses and related geoelectrical models with anomalies of the
permanent magnetic field resulted from the ground and satellite observations. The approaches for distinction of relatively low frequency
lithosphere magnetic anomalies produced by low-crustal sources are further discussed.
