A large, global positive excursion in δ 13 C (from ∼0.5 to 4.5‰) during the Late Cambrian Pterocephaliid biomere/Steptoean Stage (Aphelaspis-Elvinia zones) is documented at high stratigraphic resolution in three sections in the eastern Great Basin.

We have constructed a eustatic sea-level curve based on the stratigraphy of the tectonically stable Russian Platform. Sea-level variations measured against this reference frame were chosen as reliably representing the long-term relation of global ocean ...

We report a high-resolution stable isotope, carbonate, magnetostratigraphic, and biostratigraphic record from a 175-m drill core from the Sale Briqueterie, which is part of the Bou Regreg section in northwestern Morocco.

Abstract Detailed mapping of 150 km2 area of pediment south of Glenormiston Station Homestead, western Queensland has shown that the lower Upper Cambrian Georgina Limestone comprises over 400 m of interbedded limestone and clastic lithologies. Limestone accounts for some 30% of the formation and constitutes two distinct facies: abundantly fossiliferous,

A sequence stratigraphic framework for the late Jurassic Kimmeridgian and Bolonian stages of the Wessex–Weald Basin, southern England is proposed, based on the integration of sedimentological, geophysical and geochemical data. The NERC-funded Rapid Global Geological Events (RGGE) boreholes of Swanworth Quarry 1 and 2, and Metherhills 1, are used as ...
