The Xiangxi UNESCO Global Geopark (XUGG) contained the largest karst red stone forest landscape and Standard Stratotype-section Points (GSSPs) in Cambrian System. Those geoheritage contribute to a better understanding of Earth’s evolution. Therefore, it is great significance conduct geoscience research geosciences popularization XUGG. In this study, we took XUGG as object, analyzed situation st...

Most of the Frasnian regional stages Ukhta region, South Timan, Russia, are composed basinal deposits, however, hassi and jamieae zones Standard Conodont Zonation cannot be easily recognised in this region. A revision previously elaborated succession Timan-Pechora associations revealed that correlation problems connected with taxonomic interpretation zonal species Palmatolepis . Analysis conodo...

Abstract— The complete sections of the Lower and Upper Vendian East European Platform were opened in boreholes Belarus. This allows us to consider this region as a stratotype area. In order update paleontological characteristics Vendian, organic-walled microfossils from Bogushevsk-1, Bogushevsk-2 (Liozno), Lepel-1 reference drilled north Orsha Depression studied. transitive assemblage I with Le...

New high-resolution U-Pb dates indicate a duration of 89 ± 38 kyr for the Permian hiatus and of 14 ± 57 kyr for the overlying Triassic microbial limestone in shallow water settings of the Nanpanjiang Basin, South China. The age and duration of the hiatus coincides with the Permian-Triassic boundary (PTB) and the extinction interval in the Meishan Global Stratotype Section and Point, and strongl...

The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...

Benthic foraminifera were studied as part of an investigation of the Fortuna Section (Betic Cordillera, Southeastern Spain), undertaken to document a candidate section for the Global Stratotype Section and Point (GSSP) for the base of the Lutetian Stage (Ypresian/Lutetian boundary). Benthic foraminiferal assemblages in this section are mostly dominated by calcareous taxa (~50-96%) and by infaun...
