Показано, что температура метаморфизма составляла 450–626 °С, а давление – 3.7–9.1 кбар, т.е. PT-условия доходили до амфиболитовой фации. Геохимически амфиболиты хараматолоуской свиты разделяются на две группы. По спектрам распределения лантаноидов и современному изотопному составу Nd одна из них имеет характеристики, сходные с деплетированными базальтами N-MORB, εNd(0)=+7.0, а другая – с умеренно обогащенными базальтами E-MORB, εNd(0)=+(4.5–2.4). Установлено, что Хараматолоуская структура сложена ранне- и среднепалеозойскими толщами, вероятно, континентального подножья Русской платформы, которые претерпели основной этап складчатости и метаморфизма в позднем девоне (Rb-Sr, 366±11 млн лет). Показано, что габбро-ультрабазитовые массивы Рай-Из и Войкаро-Сыньинский на протяжении большей части своей истории (в дотриасовое время) представляли собой единый массив. Сейчас эти массивы ультрабазитов разделены молодым (триасовым) Хараматолоуским поднятием, которое является эрозионно-тектоническим полуокном, в нем обнажилась подложка надвига ультрабазитов Полярно-Уральского пояса. Хараматолоуская структура является одним из «поперечных» поднятий Урала, сформировавшихся в среднем – позднем триасе, вероятно в результате сжатия вдоль Урала. В среднепозднетриасовое время метаморфиты Хараматолоу приподнялись и те ультрабазиты, которые ранее были над этими метаморфитами, оказались смыты эрозией. Наблюдающиеся в центре Хараматолоуской структуры меланжированные серпентиниты являются сохранившимся от эрозии останцом исчезнувшей перемычки между Рай-Изом и Войкаро-Сыньинским массивами. Это существенно повышает металлогенический потенциал Войкаро-Сыньинского массива, поскольку на Рай-Изе уже найдены наиболее крупные в России месторождения хромитов.</p></abstract><trans-abstract xml:lang="en"><p>There have been petrographic, geochemical, geochronological (Rb-Sr, Ar-Ar) and isotopic (Sm-Nd) studies done on the metamorphic formations of the Kharamatolou structure of the Polar Urals, which were usually assigned to the Precambrian. The temperatures of metamorphism have been shown to range from 450 to 626 °C, and the pressures – from 3.7–9.1 kbar once PT-conditions reached the amphibolite facies. The amphibolites of the Kharamatolou formation are geochemically divided into two groups. According to the distribution spectra of lanthanides and Nd isotope composition, one group has the characteristics similar to depleted N-MORB basalts εNd(0)=+7.0, and another group – those similar to moderately enriched E-MORB basalts εNd(0)=+(4.5–2.4). It has been found that the Kharamatolou structure is probably composed of the Early to Middle Paleozoic continental rise deposit of the Russian Platform, which passed the main stage of folding and metamorphism in the Late Devonian (Rb-Sr, 366±11 Ma). The gabbro-ultrabasic Ray-Iz and Voykar-Synya massifs have been shown to be one during most of their Pre-Triassic history. Now these ultrabasite massifs are separated by the young (Triassic) Kharamatolou uplift which is an erosive-tectonic semi-window where ultrabasic rocks of the Polar-Ural belt are exposed at the base of the thrust fault. The Kharamatolou structure is one of the transverse uplifts of the Urals which probably resulted from the Middle to Late Triassic compression therealong. As a result of the Middle to Late Triassic uplift of the Haramatolou metamorphites, the overlying ultrabasites were washed away by erosion. The mélange serpentinites observed in the center of the Kharamatolou structure are uneroded remnants of the link that once existed between the Ray-Iz and Voikar-Synya massifs. This significantly increases the metallogenic potential of the Voikar-Synya massif, as the Ray-Iz hosts the largest known chromite deposits in Russia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тектоника</kwd><kwd>ультрабазитовые массивы Полярного Урала</kwd><kwd>рубидий-стронциевый метод абсолютного возраста</kwd><kwd>метаморфические сланцы</kwd><kwd>конодонты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tectonics</kwd><kwd>ultrabasic massifs of the Polar Urals</kwd><kwd>rubidium-strontium dating method</kwd><kwd>metamorphic schists</kwd><kwd>conodonts</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 22-17-00027, https://rscf.ru/project/22-17-00027/</funding-statement><funding-statement xml:lang="en">The research was carried out at the expense of the grant of the Russian Science Foundation 22-17-00027, https://rscf.ru/project/22-17-00027/.</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">Birck J.L., 1986.
