В статье рассматриваются региональные проявления в шельфовых и батиальных разрезах Пай-Хоя эвстатического события Dasberg, приуроченного к интервалу зон Lower–Middle expansa фаменского яруса верхнего девона. В задачи исследования входила оценка проявлений этого события в области перехода от мелководно-отмельных отложений Пай-Хойского карбонатного паравтохтона к глубоководным (батиальным) разрезам Карского сланцевого аллохтона.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве основы исследования выступает серия разнофациальных разрезов верхнего фамена, расположенных в разных частях Пай-Хоя: на р. Силова-Яха и руч. Тальбейшор (юго-западный Пай-Хой), реках Лымбадъяха и Песчаная (северный Пай-Хой). Фациальная интерпретация и реконструкция трансгрессивно-регрессивных последовательностей основаны на разработанных ранее седиментационных моделях отмельной и батиальной зон. В качестве стратиграфической основы использованы данные по конодонтам, а также выявленные максимумы трансгрессий и особенности изотопной записи карбонатного углерода.</p></sec><sec><title>Результаты</title><p>Результаты. В пайхойских разрезах в интервале зон Lower–Middle expansa установлены четыре трансгрессивно-регрессивных последовательности. Максимум третьей, наиболее высокоамплитудной, трансгрессии отвечает эвстатическому событию Dasberg. В рассматриваемом регионе данное событие не сопровождается признаками бескислородных условий. Изотопно-геохимических данные по разрезу р. Силова-Яха демонстрируют наличие в изотопной записи углерода структуры, аналогичной полученной ранее для североамериканских разрезов. Вероятной причиной вариации δ13Cкарб в этом интервале являются изменения климата и глобальной океанической циркуляции.</p></sec><sec><title>Выводы</title><p>Выводы. Стратиграфический интервал Lower–Middle expansa или Lower–Upper expansa (expansa s. l.) опознается по конодонтам в разрезах Пай-Хоя в различных фациях. Его более детальное расчленение и достоверная корреляция в этом регионе возможны на базе прослеживания проявлений эвстатического события Dasberg: характерной трансгрессивно-регрессивной последовательности и вариаций изотопного состава карбонатного углерода.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Research subject</title><p>Research subject. Regional manifestations of the Dasberg eustatic event in the shelf and bathyal Pai-Khoi successions. The event appears in the Lower-Middle expansa zones interval (Upper Devonian, Famennian).</p></sec><sec><title>Aim</title><p>Aim. To evaluate the manifestations of the event in the realm of transition from the shallow-water shoal succession of the Pai-Khoi carbonate parautokhtone towards the deep-water (bathyal) successions of the Kara shale allokhtone.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A number of successions comprising different facies and located in different parts of Pai-Khoi were studied: the Silova-Yakha River section and Tal’beyshor Creek section (south-western Pai-Khoi), the Lymbad’yakha section and the Peschanaya River section (northern Pai-Khoi). The interpretation of facies and the reconstruction of transgression-regression couplets were conducted based on the previously developed models of shoal and bathyal sedimentation. The stratigraphic framework comprised data on conodonts, transgression acmes, and carbonate carbon isotopic record.</p></sec><sec><title>Results</title><p>Results. The Pai-Khoi successions comprising Lower–Middle expansa zones demonstrate four transgression-regression cycles. The transgression acme of the third cycle marks the Dasberg eustatic event. The absence of anoxia is characteristic of this event in the region under consideration. The carbonate carbon isotope record of the Silova-Yakha River section shows a structure similar to that of North American successions. Variations in δ13Cкарб were likely to be caused by climate changes and perturbations of the global oceanic circulation.</p></sec><sec><title>Conclusions</title><p>Conclusions. The stratigraphic interval comprising Lower–Middle expansa or Lower–Upper expansa (expansa s. l.) zones is detected clearly in different facies. A more detailed subdivision and correlation in the region under consideration is possible on the basis of evaluating manifestations of the Dasberg eustatic event: a characteristic eustatic succession and variations of the carbonate carbon isotopic composition.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>событие Dasberg</kwd><kwd>фаменский ярус</kwd><kwd>верхний девон</kwd><kwd>конодонты</kwd><kwd>остракоды</kwd><kwd>Пай-Хой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Dasberg Event</kwd><kwd>Famennian</kwd><kwd>Late Devonian</kwd><kwd>conodonts</kwd><kwd>ostracodes</kwd><kwd>Pai-Khoi</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Груздев Д.А., Плотицын А.Н., Журавлев А.В., Антропова Е.В., Ерофеевский А.В.
