Одна из неизученных генетических разновидностей Fe-оксидных-Cu-Au (IOCG) руд, связанная с покровами базальтов, была обнаружена во время полевых работ 2013–2015 г.г. в горном хребте Сетте-Дабан. В подошве покрова базальтов (проявление Хурат) присутствует пластовая залежь гематитовых брекчий с редкой сульфидной минерализацией. Руды являются комплексными и экономически привлекательными содержания FeOобщ – 15,11–43,29 %; Cu – 0,023–0,083 %; Au – 0,1–17,5 г/т, а главным минералом-концентратором золота является гематит. Установлено, что скопления Fe-оксидных руд образовались благодаря распаду ильменита на гематит, ульвошпинель, псевдорутил и рутил. Самородное золото в рудах содержит примесь железа и палладия и не содержит серебра совсем. Одной из важных генетических характеристик руд являются постоянное присутствие монацита-Ce, химический состав которого не постоянен и определяется количеством Ce, La, Pr, Nd, Sm, Eu, Gd, Tb. Его происхождение тесным образом связано с формированием Fe-оксидных руд, где монацит встречается повсеместно в срастаниях с Ti-гематитом и псевдорутилом.</p></abstract><trans-abstract xml:lang="en"><p>Manifestations with Fe-oxide-Cu-Au±REE ores is a new direction in mining geology of Russian North-East. One of unexplored genetic varieties of the Fe-oxide Cu-Au (IOCG) ores, associated with basalt covers was discovered during field works 2013-2015, Sette-Daban ridge. The sole of basaltic cover (manifestation Hurat) include a bedded deposit of hematite breccia with sparse sulfide mineralization. Ores are complex and economically attractive the content of FeOtot – 15.11–43.29 %; Cu – 0.023–0.083 %; Au – 0.1–17.5 g/t and the main mineral-concentrator of gold is hematite. It has been established that clusters of Fe-oxide ores were formed by the decomposition of ilmenite into hematite, ulvospinel, pseudorutile and rutile. Native gold in ores contain admixture of iron and palladium and does not contain any silver at all. One of the important genetic characteristics of ores are constant presence of monazite-Ce, the chemical composition of which is not constant and is determined by the amount of Ce, La, Pr, Nd, Sm, Eu, Gd, Tb. Its origin is closely connected with the formation of Fe-oxide ores, where monazite is found everywhere in intergrowths with Ti-hematite and pseudorutile.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Fe-оксидный-Cu-Au</kwd><kwd>базальты</kwd><kwd>проявление меди</kwd><kwd>золото</kwd><kwd>монацит</kwd><kwd>Восточная Якутия.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fe-oxide-Cu-Au</kwd><kwd>basalts</kwd><kwd>copper manifestation</kwd><kwd>gold</kwd><kwd>monazite</kwd><kwd>Eastern Yakutia.</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Статья подготовлена при финансовой поддержке проекта НИР № 0381-20160004 ИГАБМ СО РАН и проекта «Стратегически важные виды минерально-сырьевых ресурсов и особенности геологического строения инвестиционно-привлекательных территорий Республики Саха (Якутия): металлогения, тектоника, магматизм, геоэкология, совершенствование поисковых и прогнозных технологий» Программы комплексных научных исследований в Респулике Саха (Якутия), направленных на развитие ее производительных сил и социальной сферы на 2016–2020 годы».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>this work was carried out with financial support of the R&amp;D plan of IGABM SB RAS, project No. 0381-2016-0004 and «Strategically important types of mineral raw material resources and feature of a geological structure of investment-attractive territories of the Republic of Sakha (Yakutia): metallogeny, tectonics, magmatism, geoecology, improvement of search and prognostic technologies» program of the complex scientific research in the Republic of Sakha (Yakutia) aimed at the development of productive forces and the social sphere for 2016-2020.</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">Вотяков С.Л., Щапова Ю.В., Хиллер В.В.
