The evolution of Earth's biogeochemical nitrogen cycle
Nitrogen is an essential nutrient for all life on Earth and it acts as a major control on
biological productivity in the modern ocean. Accurate reconstructions of the evolution of life …

Neoproterozoic postglacial paleoenvironment and hydrocarbon potential: A review and new insights from the Doushantuo Formation Sichuan Basin, China
D **ao, J Cao, B Luo, X Tan, W **ao, Y He, K Li - Earth-Science Reviews, 2021 - Elsevier
The Neoproterozoic provides an important record of glacial–postglacial paleoenvironments,
organic carbon cycling, and hydrocarbon accumulation. Here, to better understand the …

Uranium and molybdenum isotope evidence for an episode of widespread ocean oxygenation during the late Ediacaran Period
To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period,
we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic …

Ocean redox structure across the Late Neoproterozoic Oxygenation Event: a nitrogen isotope perspective
The end of the Neoproterozoic Era (1000 to 541 Ma) is widely believed to have seen the
transition from a dominantly anoxic to an oxygenated deep ocean. This purported redox …

Extensive primary production promoted the recovery of the Ediacaran Shuram excursion
Member IV of the Ediacaran Doushantuo Formation records the recovery from the most
negative carbon isotope excursion in Earth history. However, the main biogeochemical …

Palaeoceanographic controls on spatial redox distribution over the Yangtze Platform during the Ediacaran–Cambrian transition
Abstract The Ediacaran–Cambrian interval was an eventful transitional period, when
dynamic interactions between the biosphere and its physical environment allowed the Earth …

Integrated carbon, sulfur, and nitrogen isotope chemostratigraphy of the Ediacaran Lantian Formation in South China: Spatial gradient, ocean redox oscillation, and …
Abstract The Ediacaran Doushantuo Formation in South China is a prime target for
geobiological investigation because it offers opportunities to integrate chemostratigraphic …

New chronological constraints for Cryogenian to Cambrian rocks in the Three Gorges, Weng'an and Chengjiang areas, South China
Abstract The Neoproterozoic and Cambrian were two of the most dramatic periods in the
history of the Earth, because large multi-cellular animals first appeared then in the so-called …

Evidence for ca. 560 Ma Ediacaran glaciation in the Kahar formation, central Alborz Mountains, northern Iran
We report evidence for possible Ediacaran (ca. 560 Ma) glaciation from two localities of the
late Neoproterozoic Kahar Formation in the central Alborz Mountains of northern Iran. Here …
