Золото-сульфидно-кварцевые месторождения Центрального Чили - типичные объекты для старательской добычи с небольшими мощностями рудных интервалов (от первых десятков см до 1 м), прерывистым и гнездовым распределением руды и крайне неравномерными содержаниями золота.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Рассмотрены закономерности размещениия рудной минерализации на фоне результатов современных геофизических исследований литосферы: поверхности Мохо, плотности и термального режима верхней мантии. Детальные исследования золото-сульфидно-кварцевого оруденения проведены на рудном поле Япин.</p></sec><sec><title>Результаты</title><p>Результаты. Анализ металлогенической зональности территории позволил выделить центральную полосу развития золото-сульфиднокварцевых месторождений. Геодинамическая обстановка на период рудообразования характеризуется субдукцией постепенно выполаживающейся холодной океанической плиты. Показано, что разломы, контролирующие золотосульфидно-кварцевую минерализацию, - производные сдвиговой тектоники в условиях транспрессионного режима вдоль Чилийской активной окраины. На раннем этапе они развивались в правосдвиговой обстановке, что сопровождалось внедрением даек диабазов в северо-восточные разломы, а в левосдвиговый этап отлагалась золотосульфидно-кварцевая минерализация, наложенная на дайки. Приведена характеристика геологического строения месторождений рудного поля Япин. Показано, что на рудном поле развита разнообразная минерализация: меднопорфировая, IOCG (Iron oxide copper доМ)-типа и золото-сульфидно-кварцевая. По геохимическим данным, последняя характеризуется явным обогащением халькофильными элементами (Au, As, Ag, Cd, Cu, Bi, Pb, Zn, Te, Со). Заметная обогащенность руд Bi, Te и Со указывает на участие в рудообразовании магматического флюида и на сходство минерализации месторождения Эскондида с типом месторождений золота, связанных с интрузивами гранитоидов. По геохимическим особенностям золото-сульфидно-кварцевая минерализация в общей схеме зональности занимает пограничное положение между объектами ЮCG-типа и медно-порфировыми месторождениями.</p></sec><sec><title>Выводы</title><p>Выводы. Сделан вывод о самостоятельности золото-сульфидно-кварцевой минерализации и ее отличии от эпитермальных золотых месторождений. Отмечено, что в вулканических поясах Северо-Востока России весьма реальны перспективы открытия золото-сульфидно-кварцевых месторождений нетрадиционного типа, аналогичных центрально-чилийским.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Research subject</title><p>Research subject. The gold-sulphide-quartz deposits of Central Chile are typical prospecting objects, having small ore intervals (from the first tens of centimetres to 1 m), intermittent and nested ore distribution and extremely uneven gold contents.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The patterns of ore mineralization distribution are considered against the background of the results of modern geophysical studies of the lithosphere: the Moho surface, density and thermal regime of the upper mantle. Detailed studies were conducted on the Yapin ore field.</p></sec><sec><title>Results</title><p>Results. It was shown that the faults controlling gold-sulphidequartz mineralization are derivatives of shear tectonics under the conditions of a transpression regime along the Chilean active margin. At an early stage, these faults developed in a right-shift environment, which was accompanied by the introduction of diabase dikes into the northeastern faults, and gold-sulfide-quartz mineralization superimposed on the dikes was deposited during the left-shift stage. The geological structure of the deposits in the ore field Yapin was characterized. It was shown that a diverse mineralization is developed in the ore field - copper-porphyry, IOCG-type and gold-sulphide-quartz. According to geochemical data, the latter is characterized by a clear enrichment of chalcophilic elements (Au, As, Ag, Cd, Cu, Bi, Pb, Zn, Te, Co). The marked enrichment of Bi, Te and Co ores indicates the participation of magmatic fluid in ore formation and the similarity of the mineralization of the Escondida deposit with the type of gold deposits associated with granitoid intrusions. According to geochemical features, gold-sulphide-quartz mineralization in the general zoning pattern occupies a boundary position between IOCG-type objects and copper-porphyry deposits.</p></sec><sec><title>Conclusions</title><p>Conclusions. The conclusion is drawn about the independence of gold-sulphide-quartz mineralization and its difference from epithermal gold deposits. It is noted that, in the volcanic belts of the North-East of Russia, the prospects for discovering unconventional gold-sulphidequartz deposits similar to those of Central Chile are rather real.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Центральное Чили</kwd><kwd>рудное поле Япин</kwd><kwd>магматическая дуга</kwd><kwd>медно-порфировый</kwd><kwd>эпитермальный</kwd><kwd>золото-сульфидно-кварцевый</kwd><kwd>железо-оксидный</kwd><kwd>типы минерализации</kwd><kwd>геохимические особенности</kwd><kwd>зональность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Central Chile</kwd><kwd>Yapin ore field</kwd><kwd>magmatic arc</kwd><kwd>porphyry copper</kwd><kwd>epithermal</kwd><kwd>gold-sulfide-quartz mineralization</kwd><kwd>IOCG-type</kwd><kwd>deposit</kwd><kwd>geochemical features</kwd><kwd>zonation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работы выполнены при финансовой поддержке темы госзадания ИГЕМ РАН</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was financially supported by the State Project of IGEM RAS</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">Волков А.В., Сидоров А.А.
