Semenenko Institute of Geochemistry, mineralogy and Ore Formation popup.description2 Rare-earth elements (REE) and yttrium (lantanides) belong to the category of strategic metals, demand on which grows owing to the expansion of their application domain. All REE have a practical value. At the estimation of REE object the level of profitability of their development has a deciding value. There are the numerous areas of REE mineralization and the negligible quantity potentially ore-bearing object found on the Azov and Voliniya blocks. Azov Zr-REE deposit is the uniqueby by resources and specific by character of REE mineralization The main mineral of REE is magmatic britolite.The intensive fluorine-carbonic avtometasomatism took place on the postmagmatic stage, The britolite is replacement into mixture of bastnaesite and monacite. These minerals as the pseudomorph replacement by britolite are the main component of rare earth ore of Azov deposit. There are two is probed perspective rare earth object explored In surrounded of October alkaline massif. The Anadol REE ore deposit is unique industrial is represented by almost mineral allanite rock and has high temperature hydrothermal genesis. It is possible to forecast rich REE ores of hydrothermal-metasomatic genesis in the areas of surroundings of October alkaline massif . There are two objects with rare - earth mineralization known on the north-west the Ukrainian shield (USCH) : 1) metasomatite (apogranite) of Suschano-Perzhanskaya area (SPZ) and 2) Yastrubetskiy intrusive syenites stratified stock. The complex of fluorine rare metals ( REE, Y, Zr, Hf, Ta, Nb) associated with metasomatite of SPZ. As the metasomatitie is not magmatic (pegmatite) , there were not process of deep differentiation with the accumulation of REE and formation the industrial concentrations of REE minerals in them .
