Представлены первые данные по изотопному составу стронция (87Sr/86Sr) для средне- и верхнедевонских отложений центральной части Волго-Уральской нефтегазоносной провин­ции, полученные на основе анализа рамиформных элементов конодонтовых аппаратов. Стратиграфическое положение боль­шинства образцов определено по содержащимся в них плат­форменным конодонтам. Значения 87Sr/86Sr демонстрируют хорошую согласованность с глобальной стронциевой кривой, что указывает на устойчивую связь исследуемого региона с Мировым океаном на протяжении среднего и позднего девона. Полученные данные подтверждают высокую степень стратигра­фической полноты регионального разреза, несмотря на много­численные перерывы осадконакопления и частое чередование доманиковых, терригенных и карбонатных отложений.

This study presents the first 87Sr/86Sr isotope data for the Middle–Upper Devonian strata of the central part of the Volga–Ural petroleum province, which are based on ramiform conodont elements. The stratigraphic position of most samples was verified using platform conodonts they contained. The 87Sr/86Sr values obtained are consistent with the global strontium curve, indicating a contiguous connection between this region and the world ocean throughout the Devonian. These results confirm general stratigraphic completeness of the regional succession despite numerous discontinuities and the complex intercalation of black shales, siliciclastics, and carbonates.
