The geological and deep structure of the Kalba-Narym tectonic zone is considered based on the analysis of geological and geophysical materials and paleometallogenic reconstructions. Regional geophysical studies of previous years (gravity and magnetic surveys, seismic and electrical surveys) were studied. The Kalba-Narym zone is characterized by a regional gravity minimum according to gravity survey data, (this is due to the subsidence of the Mohorovichic and Konrad surfaces). It has been established that local negative gravity anomalies (linear-nodal form, predominantly northwestern orientation) correspond to the granitoid massifs of the Kalba-Narym pluton. The known pegmatite deposits of the Kalba-Narym zone are spatially associated with granitoids. Carrying out the necessary geophysical surveys can become a search criterion for discovering new deposits
