Neoproterozoic chemostratigraphy
Precambrian Research, 2010 Chemostratigraphy has diverse applications to investigating the rock record, such as reconstructing paleoenvironments, determining the tectonic setting of sedimentary basins, indirect dating, and establishing regional or global correlations. Chemostratigraphy is thus an integral component of many investigations of the ancient sedimentary record.

Carbonate successions are principal geochemical archives of the extraordinary environmental changes that occurred during the Neoproterozoic Era. In this study, we present a stratigraphic record of carbonate rare earth element (REE) compositions from Neoproterozoic and Cambrian strata in central and southern Australia.

Neoproterozoic timescales and stratigraphy
Geological Society, London, Special Publications, 2009 Abstract The Infracambrian is a term for mostly Neoproterozoic successions in North Africa and areas to the east. Its base lies within the middle Neoproterozoic period, or Cryogenian, includes the youngest Neoproterozoic period, or Ediacaran, and continues into the early Cambrian to the level at which trilobites first appear.

Reconciling proxy records and models of Earth's oxygenation during the Neoproterozoic and Palaeozoic
Interface Focus, 2020 A hypothesized rise in oxygen levels in the Neoproterozoic, dubbed the Neoproterozoic Oxygenation Event, has been repeatedly linked to the origin and rise of animal life.

Two or four Neoproterozoic glaciations?
Geology, 1998 A thick Neoproterozoic carbonate and glaciogenic succession of the southern Congo craton has yielded δ 13 C and 87 Sr/ 86 Sr records through the later Cryogenian (ca. 750–600 Ma) and earlier part of the Terminal Proterozoic (ca. 600–570 Ma). Sizeable negative δ 13 C excursions (to less than–5‰) occur above each of two glacial intervals and the 87 Sr/

The emergence and diversification of early animals is commonly thought to have coincided with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early Paleozoic, during which oxygen levels on Earth’s surface were sufficient to ...

We report Neoproterozoic (ca. 785-780 Ma) granites from the western margin of the Yangtze Block that are characterised by magmatic zircons with δ 18 O values as low as 2.98‰. The lack of low- δ 18 O magmatic zircons in the ca. 820-805 Ma rhyolite samples

Extending full-plate tectonic models into deep time: Linking the Neoproterozoic and the Phanerozoic
Earth-Science Reviews, 2020Recent progress in plate tectonic reconstructions has seen models move beyond the classical idea of continental drift by attempting to reconstruct the full evolving configuration of tectonic plates and plate boundaries.
