Реферат:	eng: In a group of natural marine apatites Ca5(PO4)3(F, OH), organic ĊH3, ĊH2-R, HOĊHR, (CH3)2-ĊR, and -Ċorg radicals are identified by EPR. The relation between the EPR spectra of the observed organic radicals, the valence form, and the structural location of impurity vanadium ions (V4+ (VO2+) on the Ca2+ II site or V5+ (VO4)3- → (PO4)3-) is established. The structure of organic radicals correlates with the type of organic matter in the sample under analysis: sapropelic or humic, depending on the climatic conditions of mineral genesis. © 2010 Pleiades Publishing, Ltd.
