“…Radioisotopic uranium-lead (U-Pb) dating of individual zircon grains, including Thermal Ionisation Mass Spectrometry with Isotope Dilution and Chemical Abrasion (CA-ID-TIMS), has been successfully applied to detailed coal basin stratigraphy for more than two decades. The radioisotopic ages facilitated intra-basin correlation and direct comparison with the International Chronostratigraphic Scale of coal seams in Australia [1,2], China [3], Eastern Europe (Donetsk Basin) [4,5], North America [6], South America [7][8][9][10] and Western Europe [11,12]. This article continues to present the results of the radioisotopic dating (CA-ID-TIMS) of coal-bearing sediments of the Kuznetsk Basin, which was started several years ago [13,14].…”

The Kuznetsk Basin (Kuzbass) is one of the largest coal basins in Siberia and a reference area for the ancient Angaraland continent. The proximity of the Kuzbass and Siberian platform caused their biotic similarities in the Late Palaeozoic. However, due to biota endemism, the Kuzbass Upper Palaeozoic does not correlate directly with the International Chronostratigraphic Chart (ICC). This paper discusses radioisotopic (CA-ID-TIMS) dating of zircons from a volcanic tuff located in the Starokuznetsk Formation. This level matches the interval of the Balakhonka/Kolchugino (B/K) floral change in Kuzbass, i.e. the gradual replacement of cordaitoid-dominated wet forests (Balakhonka flora) by more arid fern-pteridosperm-cordaitoid assemblages (Kolchugino flora). New age (276.9 ± 0.4 Ma) directly correlates the Starokuznetsk Fm with the Upper Kungurian of the ICS. We compared the Kuzbass data with data of the Western Verkhoyanie, where Middle Permian ammonoids (Sverdrupites assemblage) occur in strata recording the B/K floral change. Available (ICC) and new datings indicate the lag between the B/K floral change in low (Kuzbass) and high (Verkhoyanie) latitudes of Angaraland. The B/K floral change in the Kuzbass began in the early Late Kungurian and was completed by the end of this age. In contrast, the B/K floral change in Verkhoyanie began at the end of the Late Kungurian and was completed in the Late Wordian. The delay in the floral changes at different latitudes of Angaraland suggests that existing interregional correlations need further improvement.

“…Dates from the Paraná Basin are now abundant (e.g., Rocha-Campos et al, 2006, 2007Guerra Sommer et al, 2008a, b, c;Griffis et al, 2018Griffis et al, , 2019Santos et al, 2006;Simas et al, 2012;Jurigan et al, 2019;Cagliari et al, 2020), but vary greatly in precision. Those concentrating on the Vittatina costabilis palynological biozone are most relevant to the Dal'ny Tulkas section because several high precision CA-ID-TIMS radiometric dates (see Souza et al, 2021) indicate that the zone ranges in age from the Asselian to the early Artinskian.…”

Global Stratotype Section and Point (GSSP) for the base-Artinskian Stage (Lower Permian)

et al. 2023

The base-Artinskian Stage GSSP is defined at 0.6 m above the base of bed 4b at the Dal'ny Tulkas section in the southern Urals of Russia (53.88847N and 056.51615E). This point corresponds to the First Appearance Datum of the conodont Sweetognathus asymmetricus, which is part of a well-defined and widely distributed lineage. Additional markers for correlation include a radioisotopic age interpolated between 290.1 and 290.5 Ma, a strontium isotopic ratio of .70767, and many additional fossils groups, particularly ammonoids and fusulines, but also including small foraminiferans, radiolarians, and palynomorphs. Finally, the boundary occurs within a transgressive succession, near, or at a maximum flooding surface in many sections, thereby forming a distinctive sequence stratigraphic signature in the field. The Artinskian Stage is the third stage of the Lower Permian or Cisuralian Series.

A origem dessa rocha é a Bacia do Paraná, em pedreiras localizadas no estado de São Paulo e foi datada entre aproximadamente 301 e 357 milhões de anos (Jurigan, Ricardi-Branco, Negerato & Santos, 2019), estando relacionada a um delta fluvial em ambiente glacial (Mansur & Polk, 2018).

The landscape of Rio de Janeiro manifests a controversial relationship between urbanization and geodiversity, which can be unveiled through geotouristic tours around the city. The local geodiversity set limits and provided possibilities for the occupation of the city, as observed in the transformations during its urbanization and in the presence of rocks and fossils of different origins in the local buildings and monuments. To stimulate the conservation and dissemination of the Natural and Cultural Heritage, the Geotouristic Tour by the Historic Center of the City of Rio de Janeiro was structured to highlight the relationships between geodiversity and urbanization through the integration of Geosciences, History, and Arts
