The Neoproterozoic oxygenation event: Environmental perturbations and biogeochemical cycling
LM Och, GA Shields-Zhou - Earth-Science Reviews, 2012 - Elsevier
The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …

Oceanic oxygenation events in the anoxic Ediacaran ocean
The ocean‐atmosphere system is typically envisioned to have gone through a unidirectional
oxygenation with significant oxygen increases in the earliest (ca. 635 Ma), middle (ca. 580 …

Progress towards an improved Precambrian seawater 87Sr/86Sr curve
The secular trend of seawater strontium isotope ratio (87 Sr/86 Sr) reflects changes in the
relative contributions of continental versus mantle reservoirs to ocean composition, and …

Extensive marine anoxia during the terminal Ediacaran Period
The terminal Ediacaran Period witnessed the decline of the Ediacara biota (which may have
included many stem-group animals). To test whether oceanic anoxia might have played a …

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 …

An early Ediacaran assemblage of macroscopic and morphologically differentiated eukaryotes
The deep-water Avalon biota (about 579 to 565 million years old) is often regarded as the
earliest-known fossil assemblage with macroscopic and morphologically complex life forms …
