Исследован материал донных отложений, датируемый 1908–1910 гг. Образцы для исследования были приготовлены в виде порошка, нанесенного на токопроводящую клейкую ленту, что позволило совместить данные оптических наблюдений, электронной микроскопии и микро-РФА сканирования. Эксперименты проводились с использованием УНУ «Курчатовский центр синхротронного излучения КИСИ» с использованием конфокального рентгеновского микроскопа, разработанного в ИЯФ СО РАН. Полученные данные свидетельствуют о наличии микрочастиц с повышенным отношением Ni/Fe, возможно имеющих внеземное происхождение. Используемые методики микро-РФА-СИ позволяют проводить поиск и изучение частиц с микрометровым пространственным разрешением в матрицах различного состава на основе данных о распределении породообразующих и следовых элементов.</p></abstract><trans-abstract xml:lang="en"><p>The SR-micro-XRF method was used to search for microparticles of extraterrestrial matter in the bottom sediments of Lake Zapovednoye, located 60 km from the epicentre of the explosion of the Tunguska cosmic body (TCB) in 1908. The material of bottom sediments dating back to 1908–1910 was studied. The samples for the study were prepared in the form of a powder applied to a conductive adhesive tape, which made it possible to combine the data of optical observations, electron microscopy, and micro-XRF scanning. The experiments were carried out at the Large-Scale Research Facilities "Kurchatov Centre for Synchrotron Research" using a confocal X-ray microscope developed at the Budker Institute of Nuclear Physics SB RAS. The data obtained indicate the presence of microparticles with an increased Ni/Fe ratio, possibly of extraterrestrial origin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синхротронное излучение</kwd><kwd>микро-РФА</kwd><kwd>донные осадки</kwd><kwd>микрочастицы</kwd><kwd>Тунгусский заповедник</kwd><kwd>внеземное вещество</kwd></kwd-group><kwd-group xml:lang="en"><kwd>synchrotron radiation</kwd><kwd>micro-XRF</kwd><kwd>bottom sediments</kwd><kwd>microparticles</kwd><kwd>Tunguska Nature Reserve</kwd><kwd>extraterrestrial matter</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ИГМ СО РАН при поддержке РФФИ, грант № 19-05-50046 (микро-РФА-СИ).</funding-statement><funding-statement xml:lang="en">The work was performed as part of the state assignment of the IGM SB RAS and with RFBR support, grant 19-05-50046 (synchrotron-based XRF analyses).</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">Chandrakasan G., Ayala M.T., Trejo J.F.G., Marcus G., Carroll D.L., 2021.
