The interaction of phlogopite with carbonate melt resulted in the formation of a polymineral association of relic and newly formed phases of the phlogopite-carbonate-clinopyroxene-spinel-garnet composition coexisting with carbonate melt. By increasing the temperature from 1200 to 1300 °C in the carbonate melt increases the solubility of phlogopite and the concentrations of its components - Si, Al, Mg, K. The phase composition of the quenching phases of the carbonate melt varies from substantially carbonate with isolated microcrystals of apatite and phlogopite at 1200 °C to phlogopite-carbonate with a variety of texture ratios at 1300 °C, reflecting the spontaneous crystallization of the carbonate melt during quenching. In the studied <italic>P-T</italic>, close to the mantle adiabate, phlogopite remains stable in the presence of silicate-carbonate melt.</p></abstract><trans-abstract xml:lang="ru"><p>Изучены фазовые соотношения в системе флогопит-карбонат при Р = 3,8 ГПа, Т = 1200-1300 °С. При взаимодействии флогопита с карбонатным расплавом сформировалась полиминеральная ассоциация реликтовых и новообразованных фаз состава флогопит-карбонат-клинопироксен-шпинель-гранат, сосуществующая с карбонатным расплавом. При увеличении температуры от 1200 до 1300 °С в карбонатном расплаве увеличивается растворимость флогопита и концентраций его компонентов - Si, Al, Mg, K. Фазовый состав закалочных фаз карбонатного расплава изменяется от существенно карбонатного с изолированными микрокристаллами апатита и флогопита при 1200 °С до флогопит-карбонатного с разнообразными текстурными соотношениями при 1300 °C, отражающими спонтанную кристаллизацию карбонатного расплава при закалке. При изученных <italic>Р-Т</italic>, близких к мантийной адиабате, флогопит остается стабильным в присутствии силикатно-карбонатного расплава.</p></trans-abstract><kwd-group xml:lang="en"><kwd>phlogopite</kwd><kwd>carbonate</kwd><kwd>phase relations</kwd><kwd>experiment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>флогопит</kwd><kwd>карбонат</kwd><kwd>эксперимент</kwd><kwd>распределение элементов</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was performed on the basis of the Federal State Budgetary Science Institution “D.S.
