В статье приведены результаты изучения карбонатно-терригенного разреза венлока в бассейне р. Щугор мощностью 197.8 м, который предложен в качестве стратотипа регионального горизонта. Материалы и методы. Основой для исследований послужили многочисленные коллекции образцов из отложений нижнего силура, собранных авторами в разные годы во время полевых работ на западном склоне Приполярного Урала, поднятиях Чернова и Чернышева, и полученные биостратиграфические, палеонтологические, литологические и С-изотопные данные. Результаты. Полученные данные позволили пересмотреть некоторые сложившиеся представления о строении разреза нижнего силура и положения уровня границы между лландовери и венлоком на Приполярном Урале и выделить новое региональное подразделение с названием “войвывский”. Прослеженные условия формирования мелководных карбонатных отложений войвывского горизонта, последовательная смена зональных таксонов морской фауны в стратотипическом разрезе указывают на сходство с одновозрастными толщами на поднятиях Чернова, Чернышева и острова Долгий. Выводы. Результаты изучения венлокских отложениий на территории Тимано-Североуральского региона показали, что разрез в бассейне р. Щугор (обнажении 10ц) по степени обнаженности, установленной стратиграфической полноте и сохранности остатков макро- и микрофауны может считаться наиболее информативным на территории Североуральского региона.</p></abstract><trans-abstract xml:lang="en"><p>Research subject. The paper presents the results of a study into the carbonate-terrigenous section of 197.8 m-thick Wenlockian section in the Shchugor River basin, which is proposed as the stratotype of the regional horizon. Materials and methods. The study was based on numerous samples from Lower Silurian deposits collected by the authors in different years during fieldwork on the Western slope of the Circumpolar Urals and the Chernov and Chernyshev uplifts, as well as the biostratigraphic, paleontological, lithological, and C-isotopic data obtained during these works. Results. The obtained data allowed revising some of the established ideas about the structure of the Lower Silurian section and the position of the boundary level between the Llandoverian and Wenlockian in the Subpolar Urals and to identify a new regional subdivision with the name “Voyvyv”. The traced formation conditions of shallow carbonate sediments of the Voyvyv horizon and the consistent change of zonal taxa of marine fauna in the stratotype section indicate similarity with coeval strata on the Chernov and Chernyshev uplifts and Dolgy Island. Conclusions. The results of the study of Wenlockian Voyvyv deposits in the Timan-North Urals region showed that the section in the Shchugor River basin in outcrop 10c can be considered the most informative in the Northern Urals region in terms of exposure degree, established stratigraphic completeness, and preservation of macro- and microfauna.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нижний силур</kwd><kwd>венлок</kwd><kwd>войвывский горизонт</kwd><kwd>Приполярный Урал</kwd><kwd>поднятие Чернова</kwd><kwd>гряда Чернышева</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Lower Silurian</kwd><kwd>Wenlock</kwd><kwd>Voyvyv horizon</kwd><kwd>Subpolar Urals</kwd><kwd>Chernov Uplift</kwd><kwd>Chernyshev Ridge</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">Абушик А.Ф.
