Сборник научных трудов «Вопросы палеонтологии и региональной стратиграфии фанерозоя Европейской части России» является результатом исследований ученых и практиков из различных городов России и других стран, которые были представлены на всероссийской научно–практической конференции 22-25 сентября 2023 года. В нем представлены мнения по широкому кругу вопросов по следующим направлениям палеонтология, палеоэкология и тафономия, региональная стратиграфия фанерозоя Европейской части России, палеобиогеография, история палеонтологии России, сохранение геологического наследия, геотуризм, палеонтологические коллекции музеев России.
Geochronology, including thermochronology, is an essential component of practically all modern Earth and planetary science and provides fundamental information for many other areas, including archeology, marine sciences, and ecology. Geochronology establishes the timing of critical events ranging from the age of the Earth to stratigraphic boundaries, and it provides unique constraints on the pace and dynamics of processes ranging from condensation of the solar nebula to planetary differentiation to surface exposure to biologic evolution. Given that Earth and planetary scientists commonly seek to understand relationships between events or phenomena for which physical evidence is incomplete or ambiguous, establishing temporal relationships through geochronology often provides a substantial basis for causality arguments.
Although the concept of geochronology has existed for millennia, and the particular name has been around since 1893, most scientists would probably agree that the modern practice or discipline is based on application of radioisotopic (or cosmogenic) systems in natural materials, which has existed for only a little more than a century (or less). Even into the 20th century, the geologic timescale floated freely in time. Geologists had established sequences of evolutionary and orogenic events in the rock record, but numerical estimates ranged widely, more so further back in geologic history. Without precise dates, only poorly constrained arguments could be made about the relative durations and the time separating major events in the geologic record. Likewise, prior to radioisotopic methods, the best available estimates for the age of the Earth (and solar system) disagreed by several orders of magnitude. The rather sudden recognition of nuclear structure and radioactive decay around the beginning of the 20th century, changed Earth and planetary science fundamentally. The very first radioisotopic dates measured increased the previously deduced minimum age of the Earth by about an order of magnitude, and subsequent work, less than 100 years ago, increased it by another factor of ten. <...>
This Atlas is designed to be a useful work of reference in an easily-handled format amenable to future expansion both by the E.A.E.G. and the users themselves. It is intended for geoscientists in both the industrial and academic spheres who are at an early career stage, and who would find it of value to see how the interpretation of a wide variety of types of structure is approached on actual examples. The notes accompanying the examples have been kept as concise as is consistent with clarity, and some guidance for further study has been given in the form of a list of key words, and brief references with each group of examples; these in turn will open up the literature.
Палеонтология Эукариоты докембрия Вендская система: предкембрийская геобиологическая среда Вендская фауна севера Русской платформы О центрах происхождения кембрийских фаун Сравнительная классификация современных и ископаемых органогенных построек Эволюция Cnidaria К вопросу об исследовании микроструктуры хиолительминтов
Работа посвящена обоснованию стратиграфической схемы верхнедокембрнйскнх и кембрийских отложений Восточно-Европейской платформы. В составе венда и кембрия выделены стратиграфические горизонты, прослеженные на обширных площадях. Эти горизонты, выделенные для верхов докембрия и кембрия имеют четкое палеонтологическое обоснование и являются основой для корреляции разрезов.
