Abstract: The results of the study of fluorspar, found in the recently drilled borehole, are presented. Thickness of fluorite-bearing beds is approximately 5 and 2 m at the depths of 160—170 m. According to X-ray analysis the fluorite content in the rock is mainly ≥65 % that corresponds to metallurgical ore grade. The deposit belongs to a rare type of metasomatic formations that appeared in the carbonate rocks of Tournaisian age (С1), owing to introduction into mineral formation medium of mainly one element — fluorine. Fluid flows with fluorine belong to the end products of magma degassing that participated in the development of Pokrovo-Kyriyivo gabbro-syenite massif. The temperature of fluorite formation as a result of decrepitation of gas-liquid inclusions (liquid ~90—95 %) is ≤120—160 °C. The contents of REE in fluorite were determined by ICP-MS analyzer using ELE MENT -2. Сhondrite-normalized REE patterns in fluorite and apatite Pokrovo-Kyriyivo deposit and massif are close to each other Eu/Eu * = 0.6—0.8 and 0.9.
Keywords: Pokrovo-Kyriyivo deposit, mineral composition, fluorite, calcite, dolomite, chondrite-normalized REE patterns.
