DIBROVSKOE URANIUM-TORIUM-RARE-EARTH ORE OCCURRENCE OF THE UKRAINIAN SHIELD (LITHO-STRATIGRAPHIC CRITERIА OF THE GENESIS AND LOCALIZATION OF ORE BODIES)

The paper compares the Dibrovskoe uranium-thorium-rare-earth ore occurrence of the Ukrainian shield (northern Azov region) by a num-ber of criteria (structural-tectonic, formational, stratigraphic, geochronological, lithological, mineral-petrographic, geochemical) with similar well-known objects of...
