All of them belong to one of three metallogenic types: alkaligranitic, foidic or carbonatitic. The distribution of their resources on the scale of geological time is distinctly discrete. The deposits were formed from the Middle Paleoproterozoic to the Cenozoic. The Rodinian, Pangean and Amasian supercontinent cycles are the most productive ones in terms of accumulated niobium resources. These three cycles stand out in a leading role of the deposits related to carbonatite complexes.</p></abstract><trans-abstract xml:lang="ru"><p>Проведён анализ металлогении ниобия на протяжении геологической истории на основе данных по 45 крупнейшим месторождениям мира. Все они принадлежат к одному из трёх типов: щёлочно-гранитному, фоидному или карбонатитовому. Месторождения формировались с переменной интенсивностью в интервале от середины палеопротерозоя до кайнозоя. Больше всего ресурсов ниобия накоплено в объектах, формировавшихся в течение родинийского, пангейского и амазийского суперконтинентальных циклов. Эти циклы выделяются ведущей ролью месторождений, связанных с карбонатитовыми комплексами.</p></trans-abstract><kwd-group xml:lang="en"><kwd>niobium deposits</kwd><kwd>metallogeny</kwd><kwd>carbonatite</kwd><kwd>nepheline syenite</kwd><kwd>alkaline granite</kwd><kwd>geological history</kwd><kwd>supercontinent cycle</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>месторождения ниобия</kwd><kwd>металлогения</kwd><kwd>карбонатиты</kwd><kwd>нефелиновые сиениты</kwd><kwd>щелочные граниты</kwd><kwd>геологическая история</kwd><kwd>суперконтинентальный цикл</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Presidium of the Russian Academy of Sciences</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Президиум РАН</institution></institution-wrap></funding-source><award-id></award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Presidium of the Russian Academy of Sciences</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Президиум РАН</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Schulz K. J., Piatak N. M., Papp J. F.
