Реферат: | eng: An analysis of a number of samples from the Tomtor deposit of Nb and rare-earth elements (Republic of Saha (Yakutia)) by X-ray diffractometry, IR spectroscopy, and Raman spectroscopy makes it possible to cover the structural organization of minerals and their components from the long-range to the mid- and short-range orders. The apatites present in the samples are characterized by a large variety of anion and cation substitutions (including rare-earth elements) in various structural sites. Raman microspectroscopy revealed some specific features, inherent in molecular biomarkers (specifically, a band due to double bonds -C=C- in the central part of the polyene chain of carotenoids, which characterize cyanobacteria associated with apatite), which is a direct proof of participation of microorganisms in the formation of apatites in rocks of this deposit.
