TLDR
In this article, the Yangtze Platform of South China has been investigated for the purpose of constructing a framework for global chronostratigraphic correlation of Ediacaran strata, and the results indicated that the earliest known metazoan biotas do not constitute two temporally separate evolutionary lineages preceding the Cambrian explosion of animal life.About:

Pulsed oxidation and biological evolution in the Ediacaran Doushantuo Formation
Kathleen A. McFadden,Jing Huang,Xuelei Chu,Ganqing Jiang,Alan J. Kaufman,Chuanming Zhou,Xunlai Yuan,Shuhai Xiao +7 more
TL;DR: High-resolution geochemical data from the fossil-rich Doushantuo Formation in South China are reported that confirm trends from other broadly equivalent sections and highlight key features that have not been observed in most sections or have received little attention.

A Stratified Redox Model for the Ediacaran Ocean
TL;DR: A detailed spatial and temporal record of Ediacaran ocean chemistry for the Doushantuo Formation in the Nanhua Basin, South China is presented, finding evidence for a metastable zone of euxinic (anoxic and sulfidic) waters impinging on the continental shelf and sandwiched within ferruginous [Fe(II)-enriched] deep waters.
Journal ArticleDOI
Stratigraphy and paleogeography of the Ediacaran Doushantuo Formation (ca. 635-551Ma) in South China
TL;DR: The Doushantuo Formation (ca. 635-551 ǫ Ma) is one of the most intensively investigated Ediacaran units in the world.

Ocean oxygenation in the wake of the Marinoan glaciation

TL;DR: The data provide evidence for an early Ediacaran oxygenation event, which pre-dates the previous estimates for post-Marinoan oxygenation by more than 50 million years, and seem to support a link between the most severe glaciations in Earth’s history, the oxygenation of the Earth's surface environments, and the earliest diversification of animals.
Journal ArticleDOI
A burial diagenesis origin for the Ediacaran Shuram–Wonoka carbon isotope anomaly
TL;DR: In this article, the presence of negative δ13C excursions in Ediacaran-age carbonate sediments has been identified in several sections globally, but are not recognized in all sections of similar age.

A Neoproterozoic Snowball Earth
TL;DR: Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity in the surface ocean collapsed for millions of years.
Journal ArticleDOI
U-Pb ages from the neoproterozoic Doushantuo Formation, China
TL;DR: U-Pb zircon dates from volcanic ash beds within the Doushantuo Formation (China) indicate that its deposition occurred between 635 and 551 million years ago, indicating synchronous deglaciation.

Geochronology of Neoproterozoic syn-rift magmatism in the Yangtze Craton, South China and correlations with other continents: evidence for a mantle superplume that broke up Rodinia
TL;DR: In this article, the authors showed that there were two major phases of widespread bimodal magmatism in South China during the Neoproterozoic, one starting before the continental rift but continued into the first two stages of the rifting.
Journal ArticleDOI
History of Neoproterozoic rift basins in South China: implications for Rodinia break-up
TL;DR: In this paper, a first-order analysis of the Neoproterozoic continental rift basins in South China is presented, focusing on the north-south trending Kangdian basin in the western part, and the Yangtze-side of the northeasterly-trending Nanhua basin.

Neoproterozoic variations in the C-isotopic composition of seawater: stratigraphic and biogeochemical implications.
Alan J. Kaufman,Andrew H. Knoll +1 more
TL;DR: The recent proliferation of stratigraphic studies of delta 13C variation in carbonates and organic C in later Neoproterozoic and basal Cambrian successions indicates a strong oscillating trend in the C-isotopic composition of surface seawater.
