Условно магматический минглинг разделен на две основные группы. Первая группа («плутоническая») – это небольшие базитовые включения, равномерно распределенные в объеме гранитоидных тел, либо вытянутые рои и шлейфы мелких тел. Вторая группа («комбинированные дайки») представлена композитными дайками, в пределах которых наблюдаются признаки механического смешения базитовых и кислых расплавов. Несмотря на сходство структурно‐текстурных особенностей и признаков механического смешения расплавов, обе группы имеют явные различия: пропорции объемов контрастных расплавов, длительность становления, место смешения расплавов, тектонические обстановки. Существующие модели не могут объяснить появление структур магматического минглинга в отдельных дайках. В данной работе вопросы механизмов смешения контрастных по составу расплавов рассмотрены на примере геологических объектов Западного Сангилена (ЦАСП). Рассмотрены общие и частные параметры комбинированных даек участков «Тавыт‐Даг» и «Сайзырал». Предложены модели сдвиговой дилатации и диспергирования для объяснения механизмов магматического минглинга в композитных дайках жильного типа.</p></abstract><trans-abstract xml:lang="en"><p>This article is focused on the intrusion and formation of combined dykes. Two main groups of conventionally magmatic mingling are distinguished: (1) plutonic bodies, and (2) combined dykes. The first group is represented by small basite inclusions that are uniformly scattered in granitoid bodies, and includes elongated swarms and tails of small bodies. The second group includes composite dykes with the indicators of mechanical mingling of basic and acid melts. Despite the similarities in the structural and textural features and the indicators of mechanical mingling of melts, these two groups are characterized by clearly different proportions of the volumes of contrasting melts and differ in the duration of formation, place of melt mingling, and tectonic setting. None of the available models was able to explain the occurrence of magmatic mingling structures in individual dykes. In our study, the mingling mechanisms of contrasting melts are discussed using the data on the geological objects located in West Sangilen, an area of the Central Asian Orogenic Belt (CAOB). The general and specific parameters of combined dikes of the Saizyral and Tavyt‐ Dag sites are considered. The models of shear dilatation and dispersion are proposed for explaining the mechanisms of magmatic mingling in combined dykes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>минглинг</kwd><kwd>комбинированная дайка</kwd><kwd>сетчатая интрузия</kwd><kwd>сдвиговая зона</kwd><kwd>тектономагматическая эволюция</kwd><kwd>Сангилен</kwd><kwd>Юго‐Восточная Тува</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mingling</kwd><kwd>combined dike</kwd><kwd>net‐veined intrusion</kwd><kwd>shear zone</kwd><kwd>tectono‐magmatic evolution</kwd><kwd>Sangilen</kwd><kwd>South‐East Tuva</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке РФФИ (проекты № 16‐05‐01011, 18‐35‐00467), ИГМ СО РАН (проект № 0330‐2016‐0003), а также Министерства образования и науки РФ (проект № 5.1688. 2017/ПЧ)</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">Биндеман И.Н.
