- Аннотация: The radioholographic method is the promising tool for solving problems of ore geophysics. Holographic reconstruction of geoelectric inhomogeneities in the earth's crust allows to effectively localize in space anomalous regions with high electrical conductivity, associated with local ore bodies, by using areal surface observations of the electromagnetic field. However, the analysis of previous experimental and model results demonstrated the possibility of "false" anomalies in the holographic reconstruction of the distribution of inhomogeneities. It was suggested to conduct observations at several frequencies as one of the ways of rejection of such "false" anomalies. So in 2017 extended field works were conducted at the site Loipishnjun in the Monchegorsk ore region by using the two-frequency radioholographic method. Results of field experimental studies have shown that the two-frequency modification of radioholographic method greatly improves the reliability of the holographic reconstruction of distribution of inhomogeneities in the earth's crust. The comparison of results of the holographic reconstruction at different frequencies allows one to reject "false" anomalies, and to identify anomalous zones, which can be associated with ore bodies
