      <abstract xml:lang="ru">
        <p>В результате впервые проведенного изотопно-геохимического исследования рутила из полиминерального рудопроявления Ичетъю на Среднем Тимане, выполненного локальным методом LA-ICP-MS и «классическим» методом TIMS, установлено, что поступивший из различных источников разновозрастный (предположительно с возрастом около 1000, 1660, 1860 и 1980 млн лет) рутил претерпел общее для всех его разновидностей термальное воздействие в результате процесса с возрастом около 580 млн лет. Результаты геохронологического исследования рутила согласуются с проведенным ранее U-Pb датированием циркона из проявления Ичетъю и Пижемского месторождения. Cогласно современным представлениям температура закрытия U-Pb системы в рутиле превышает 500 °С, что предполагает достаточно высокотемпературные условия гидротермальной переработки рутила при формировании рассматриваемых месторождений в рифейское время.</p>

      <abstract xml:lang="en">
        <p>A study on the U-Pb age of rutile from the Ichetju polymineral occurrence has been done for the first time by LA-ICP-MS and TIMS methods. It was established that rutile originates from various sources with different ages (presumably, ca. 1000, 1660, 1860 and 1980 Ma), but all the rutile types have undergone a common thermal event at ca. 580 Ma. Obtained results are consistent with U-Pb zircon data for the Ichetju occurrence and the Pizhemskoe deposit. According to modern concepts, the closure temperature for the U-Pb system in rutile is higher than 500 °С, which suggests fairly high-temperature conditions of the rutile hydrothermal transformation during the formation of the deposits in Riphean. Obviously, a placer hypothesis of formation of titanium deposits of the Middle Timan which is supported by a number of researchers does not explain such temperature of rutile alteration.</p>
