The Ediacaran Global Stratotype Section and Point has now been defined at the base of the Nuccaleena Formation in the Flinders Ranges National Park, South Australia. This GSSP marks the end of a major glacial epoch. In the absence of definitive biozones marking the base of the Ediacaran, the utility of this “cap carbonate’ for correlation will depend on the verification of a global fingerprint ...

In the Late Paleozoic paleogeography, the Laibin area, South China, locates in the south-eastern margin of the Laibin-Heshan isolated carbonate platform. One global stratotype section for The Guadalupian–Lopingian (G/L) (The end of the Mid-Permian) transition is located in the Tieqiao section in Laibin area, which is regarded as appropriate one for the study. Based on the analysis, seven facies...
