The accumulation of oxygen is one of the most important characteristics that distinguish
Earth from other planets in the solar system, which is also considered to be the key factor …

Abstract Early Cambrian basin in South China has deposited successive sedimentary rocks,
which not only recorded geochemical information of the variation of palaeo-ocean …

The redox structure of the water column in anoxic basins through geological time remains
poorly resolved despite its importance to biological evolution/extinction and biogeochemical …

Oxygen availability is crucial for the evolution of eukaryotes in geological history, but the
redox conditions of the mid-Proterozoic atmospheric-oceanic system remain vigorously …

Controls on Mesoproterozoic ocean redox heterogeneity, and links to nutrient cycling and
oxygenation feedbacks, remain poorly resolved. Here, we report ocean redox and …

The later stages of Earth's transition to a permanently oxygenated atmosphere during the
Great Oxidation Event (GOE;∼ 2.43–2.06 Ga) is commonly linked with the suggestion of an …

The Mesoproterozoic ocean was previously proposed to be characterized by low oxygen
concentrations that may have resulted in a stasis in eukaryotic evolution. Recent studies …

The stratigraphic correlation of the ca. 2353±18 Ma to 2316±7 Ma Duitschland and
Rooihoogte formations, Transvaal Supergroup, South Africa, becomes critically important …

Enhanced continental phosphorus input into the ocean has been suggested as a potential
trigger for the transient oxygenation events during the mid‐Proterozoic; however, the …

Abstract The mid‐Proterozoic (∼ 1.8–0.8 Ga) ocean‐atmosphere system is hypothesized to
have experienced fluctuations in redox conditions with transient oxygenation events. One of …
