      <abstract xml:lang="ru">
        <p>Представлены данные по содержанию и распределению редких и редкоземельных элементов (метод SIMS) в секторах и зонах роста крупного кристалла циркона из миаскитовых пегматитов Вишневогорского массива. Морфология кристалла циркона представляет собой комбинацию дипирамиды {111} и призмы {010}. Установлено, что для сектора роста дипирамиды {111} свойственно почти на порядок более высокое содержание Y, Nb, REE, Th; бóльшая величина Th/U отношения и значения Eu/Eu*; спектры распределения REE демонстрируют более пологий характер по сравнению с сектором роста призмы {010}. Выявлено закономерное уменьшение содержания редких и редкоземельных элементов в направлении от центральной к краевой зоне роста кристалла. Установлена плавная тенденция к регрессии температуры кристаллизации циркона от 960 °С в центральной зоне до 740 °С в краевой зоне сектора дипирамиды и 700-650 °С в секторе призмы, что может быть отражением термальной эволюции процесса кристаллизации. Предполагается, что кристаллизация центральной зоны циркона происходила на ранних этапах из сравнительно обогащенного редкими элементами расплава. Завершалась кристаллизация при более низких температурах, вероятно, одновременно с образованием минералов-концентраторов REE, что привело к закономерному снижению содержания редких и редкоземельных элементов в расплаве и, как следствие, в кристаллизующемся из него цирконе.</p>

        <p>Data on the content and distribution of trace and rare-earth elements (SIMS method) in sectors and growth zones of a large zircon crystal from miaskite pegmatites of the Vishnegogorsky massif are presented. The morphology of the zircon crystal is a combination of a dipyramid {111} and prism {010}. It has been established that the growth sector of dipyramid {111} is characterized by almost one order of magnitude higher contents of Y, Nb, REE, Th; higher Th/U and Eu/Eu* values; REE distribution spectra are flatter compared to prism {010} growth sector. A regular decrease in the content of trace and rare-earth elements in the direction from the central zone to the marginal zone of crystal growth was revealed. A smooth regression of zircon crystallization temperature of zircon from 960 °C in the central zone to 740 °C in the marginal zone of the dipyramid sector and 700-650 °C in the prism sector has been revealed, which may be a reflection of thermal evolution of the crystallization process. It is assumed that crystallization of the central zone of zircon occurred at early stages from a relatively trace-еlement-rich melt. The crystallization was completed at lower temperatures, probably, simultaneously with the formation of REE-concentrating minerals, which resulted in natural decrease of content of trace and rare-earth elements in the melt and, consequently, in zircon crystallizing from it.</p>
