The Azov rare-earth deposit of the Ukrainian Shield, based on the characteristic features (major and minor ore minerals, accessory minerals, minerals of ore-bearing metasomatic changes, geochemical features), has been compared with similar rare earth rare-earth deposits enriched with yttrium REE, HREE and zirconium associated with subalkaline granitoids. The results of the comparison showed, that the Azov deposit does not have direct analogs of this type (with the exception of the Yastrebetskoe ore occurrence of USH) among the rare-earth deposits of the world. At the same time, the Azov rare-earth deposit is a large deposit where the reserves of useful components exceed the reserves of rare-earth ores of known industrial deposits in Canada and North America. Preliminary geological and economic assessment of the Azov deposit unambiguously showed its industrial significance. For several decades the development of the deposit, depending on the method of development and the depth of the technological redistribution, can bring an annual net profit of tens of millions,and for the entire development period of several hundred million dollars.
Keywords: Azov rare-earth deposit, Ukrainian Shield, geochemistry, geological and economic assessment.
