Целью исследований было определение эволюции состава айликитового расплава и идентификация изученных лампрофиров Большетагнинского массива. Изучены шпинелиды из трех даек Большетагнинского массива, имеющих разный минеральный состав основной массы, но схожие текстурно-структурные особенности (BTG 2/21, TGK 3, BTG 6/21). С помощью электронного микроскопа и микрозонда определено содержание основных элементов и микрокомпонентов в шпинелидах. Все кристаллы шпинелидов зональные, и по составу авторами были выделены следующие типы: хромиты (Chr), алюмохромиты (Al-Chr), хромистые магнетиты (Cr-Mgt), титаномагнетиты (Ti-Mgt), магнетиты (Mgt). Состав шпинелидов из образца BTG 2/21 ультраосновных лампрофиров Большетагнинского массива показывает следующий тренд изменения: хромит→ алюмохромит→ хромистый магнетит→ титаномагнетит→ магнетит. Образец TGK 3 содержит шпинелиды с изменением состава от хромитов к хромистым магнетитам. Хромитовые ядра из образца BTG 6/21 обрастают хромистыми магнетитами, затем титаномагнетитами.</p><p>Предполагается, что первичный расплав, из которого кристаллизовались первичные хромиты, для всех изученных образцов был один и тот же. После формирования хромитов из единого расплава (возможно в единой камере) каждая порция расплава переживает свою историю становления, что подтверждается исследованиями шпинелидов.</p></abstract><trans-abstract xml:lang="en"><p>This paper provides the results on spinel sampled from ailikites of the Bolshetagninskii massif of the East Sayan region. The study aimed to determine the history of formation of ultramafic lamprophyres of the Ziminsky complex. Spinel from three dikes of the Bolshetagninskii massif with different mineral compositions of the groundmass but similar textural and structural features (BTG 2/21, TGK 3, BTG 6/21) was analyzed. The content of the main elements and microcomponents in spinel was determined using electron microscope and microprobe. All spinel crystals are zonal, the following types have been identified with regard to the composition: chromites (Chr), aluminum-chromites (Al-Chr), chromium magnetites (Cr-Mgt), titanomagnetites (Ti-Mgt) and magnetites (Mgt). The composition of spinel from sample BTG 2/21 of ultramafic lamprophyres of the Bolshetagninskii massif shows the following trend: chromite→ aluminum-chromite→ chromium magnetite→ titanomagnetite→ magnetite. Sample TGK 3 contains spinel with compositional change from chromite→ chromium magnetite. Chromite cores from sample BTG 6/21 are overgrown with chromium magnetite, as well as titanomagnetite.</p><p>We assume the primary melt, from which the primary chromite crystallized, to be the same for all samples studied. After chromite formed from the same melt and possibly in the same chamber, each melt portion experiences its own history of formation as evidenced by spinel study.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>шпинелиды</kwd><kwd>кимберлитоподобные породы</kwd><kwd>зональные кристаллы</kwd><kwd>айликиты</kwd><kwd>зиминский комплекс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spinel</kwd><kwd>kimberlite-like rocks</kwd><kwd>zonal crystals</kwd><kwd>ailikite</kwd><kwd>Ziminsky complex</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Петрографические исследования проводились за счет средств проектов НИР ИГМ СО РАН (FWZN-2022-2025) и ГИН СО РАН (АААА-А21-121011390002-2), состав шпинелидов изучался за счет средств проекта РНФ 19-17-10004.
