The main results are in the regional forecast accumulations of ore minerals on the basis of the construction of the bulk conductivity in the geoelectric models in the Azov and Ingulmegablock of the Ukrainian shield, in Golovanevsk and Nemirov-Kocherov suture zone. For time 2012-2016 years were carried out a detailed study of the geoelectrical conductivity anomalies associated with regional metasomatiс zones of the Ukrainian shield.In the Azov block of the promising areas for the discovery of rare-metal mineralization in the Central Azov region are the areas of distribution of rare-metal granites Kamennayamogila complex with a widely developed zones of autometasomatic (greisenization). In the East Azov region are zones of fenitization associated with alkaline magmatism, particularly widespread on the Oktyabrskiyarrea.In Ingul block of the Ukrainian shield metasomatiсzone dedicated to Kirovohrad deep break with gold ore deposits within Klintsy-Ingul metasomatic zones and zones of albitites with uranium deposits.In the Golovanevsk suture zone with widespread zones of metasomatic (Khmelnitsky and Talnov deep breaks) disseminated gold deposits of Savran ore field.In the Western part of the Ukrainian shield titanium-zirconium and tantalum-niobium ore occurence gravitate mainly to the deep fault zones Nemirov-Kocherov suture zone.Regional and local metasomatic zones within them are allocated in the form of a low-resistivity anomalies of electrical resistivity (high electrical conductivity). Built bulk conductivity model to allow these regions to identify the most promising areas in search of occurrences associated with metasomatic. Carrying zones metasomatic detailed geoelectric studies will highlight the area, promising to further prospecting activities.
Keywords: metasomatites, prediction, ore occurrence, geoelectric model, Ukrainian shield.
