Приведены результаты Sm-Nd и Rb-Sr изотопного датирования пирохлоровых карбонатитов Вишневогорского ниобиевого месторождения, Ильмено-Вишневогорский щелочной комплекс (ИВК), Южный Урал. ИВК является представителем карбонатитовых комплексов линейного типа, с которым связаны редкометалльные (Nb-Zr-TR) месторождения и рудопроявления, время и продолжительность формирования которых остается предметом дискуссий. В целях определения возраста карбонатитов и связанного с ними ниобиевого оруденения проведены измерения Sm-Nd и Rb-Sr изотопных составов и концентраций элементов в валовых пробах пирохлоровых карбонатитов и слагающих их минералах (пирохлоре, кальците, апатите, биотите). Методы. Измерения изотопного состава и концентраций Sm и Nd проводились на семиканальном массспектрометре Finnigan MAT-262 RPQ (TIMS) в статическом режиме (ГИ КНЦ РАН, г. Апатиты). Изотопный состав и концентрации Rb и Sr измерялись на термоионизационном масс-спектрометре Triton Plus (ЦКП “Геоаналитик”, ИГГ УрО РАН, г. Екатеринбург).  Результаты. C использованием Sm-Nd и Rb-Sr изотопных систем определен возраст кристаллизации пирохлоровых карбонатитов рудной зоны 140 Вишневогорского месторождения. Минеральная Sm-Nd изохрона (5 точек) показала возраст 229 ± 16 млн лет, минеральная Rb-Sr изохрона (5 точек) дала близкий возраст 250.5 ± 1.2 млн лет.  Заключение. Результаты Sm-Nd и Rb-Sr датирования свидетельствуют о том, что пирохлоровые карбонатиты рудной зоны 140 кристаллизовались ≈250 млн лет назад на этапе постколлизионного растяжения, возможно, в связи с эксгумацией комплекса, сопровождающейся декомпрессией, участием флюидов, частичным плавлением пород, растворением и переотложением вещества ордовикско-силурийских щелочно-карбонатитовых комплексов.</p></abstract><trans-abstract xml:lang="en"><p>Research subject. In this research, we carried out Sm-Nd- и Rb-Sr-dating of pyrochlore carbonatite from the Vishnevogorsky niobium deposit, Ilmeno-Vishnevogorsky Alkaline Complex, Southern Urals. IVC is located in the Ural fold region and is a carbonatite complex of the linear type. Rare metal (Nb-Zr-TR) deposits and occurrences are related to IVC. The age and the duration of IVC deposits formation remains a matter of debate. To determine the age of IVC carbonatites and related niobium ore, we measured Sm-Nd and Rb-Sr isotopic compositions and concentrations of the elements in the minerals (pyrochlore, calcite, apatite, biotite) and bulk sample of pyrochlore carbonatite.  Materials and methods. The Sm and Nd isotopic compositions and concentrations were determined on a Finnigan MAT-262L (RPQ) seven-collector mass spectrometer in the static regime at the Geological Institute of the Kola Scientific Center, Apatity, Russia. The Sr and Rb isotopic compositions and concentrations were determined on thermos-ionization mass spectrometer Triton Plus (“Geoanalitik”, IGG UD RAN, Ekaterinburg, Russia).  Results. Age of pyrochlore carbonatites from ore zone 140 (Vishnevogorsky deposit, IVC) defined by Sm-Nd and Rb-Sr isotopic methods. Mineral Sm-Nd-isochron (5 points) indicated age 229 ± 16 Ma, mineral Rb-Sr-isochron (5 points) showed similar age 250.5 ± 1.2 Ma.  Conclusions. Results Sm-Nd и Rb-Sr dating indicate that the pyrochlore сarbonatites of ore zone 140 crystallized ≈ 250 Ma ago, at the stage of the postcollisional extension, possibly, in connection with exhumation complex, which was accompanied by decompression, partial melting of rocks, involving fluids, dissolution and precipitation of Ordovician-Silurian alkaline-carbonatitе complex. Thus, the formation of the IVC carbonatites and related Nb-ore, which began in Silurian (S), continued in Permian (P) and Triassic (T1-2) and was associated with the post-collision stage of tectonic activity in the Ural Fold Belt.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонатиты</kwd><kwd>пирохлор</kwd><kwd>Nb месторождения</kwd><kwd>Sm-Nd и Rb-Sr датирование</kwd><kwd>Урал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbonatites</kwd><kwd>pyrochlore</kwd><kwd>Nb-deposits</kwd><kwd>Sm-Nd- and Rb-Sr-dating</kwd><kwd>Urals</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РФФИ № 17-05-00154 и темы государственного задания ИГГ УрО РАН № АААА-А18-118052590028-9</funding-statement><funding-statement xml:lang="en">This work supported by grant RFFI No. 17-05-00154 and in accordance with the theme No. AAAA-A18-118052590028-9 of the IGG UB RAS state assignment</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Баженов А.Г.
