Для расчета температур используются результаты микрозондового (EPMA) анализа главных и примесных элементов в оливине и хромшпинелиде метеоритов Каргаполье, Орловка, Саратов, Еленовка, Бушхов, Бюрбёлле и Княгиня. Полученные температуры согласуются с концентрической моделью строения планетезималей, при которой наиболее метаморфизованные хондриты находятся ближе к источнику нагрева (Бушхов, L6 – 734 °С), метеориты 5-го петрографического типа (п.т.) занимали промежуточную позицию (Орловка, H5 – 687 °С; Еленовка, L5 – 691 °С; Княгиня, LL5 – 700 °С), а хондриты 4-го п.т. находились ближе к поверхности (Каргаполье, H4 – 691 °С; Саратов, L4 – 670 °С; Бюрбёлле, LL4 – 682 °С). Метеориты Каргаполье и Саратов характеризуются несогласными с концентрической моделью оценками температур уравновешивания Mg и Fe, что объясняется индивидуальной историей метеорита (например, импактный метаморфизм, медленный и продолжительный нагрев).</p></abstract><trans-abstract xml:lang="en"><p>The article provides an evaluation of thermal metamorphism temperatures on chondrite parent bodies using an olivine-Сr spinel geothermometer. To calculate temperatures, the results of EPMA analysis of the major and trace elements in olivine and Cr spinel of Kargapole, Orlovka, Saratov, Elenovka, Buschhof, Bjurböle and Knyahinya meteorites are used. The obtained temperatures are consistent with the onion-shell model of the planetesimal structure, in which the most metamorphosed chondrites are closer to the heating source (Buschhof, L6-734 °C), meteorites of the 5th petrologic type (p.t.) occupied an intermediate position (Orlovka, H5 – 687 °С; Elenovka, L5 – 691 °С; Knyaginya, LL5 – 700 °C), and the chondrites of the 4th p.t. were closer to the surface (Kargapole, H4 – 691 °C; Saratov, L4 – 670 °С; Bjurböle, LL4 – 682 °C). The Kargapole and Saratov meteorites are characterized by evaluation of Mg and Fe equilibrium temperatures that disagree with the onion-shell model, which can be explained by the individual history of the meteorite (for example, impact metamorphism, slow and prolonged heating).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метеорит</kwd><kwd>равновесный обыкновенный хондрит</kwd><kwd>микрозондовый анализ</kwd><kwd>хромшпинелид</kwd><kwd>оливин</kwd><kwd>геотермометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meteorite</kwd><kwd>equilibrated ordinary chondrite</kwd><kwd>microprobe analysis</kwd><kwd>Cr spinel</kwd><kwd>olivine</kwd><kwd>geothermometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках темы НИР ИГГД РАН № FMUW-2022-0005.
