“…The Yunmengshan IF samples have markedly positive δ 53 Cr auth values (δ 53 Cr auth = 1.11-2.53‰), higher than records of the BSE (−0.12‰) and the shale and other ironstones before 1.6 Ga (δ 53 Cr auth < 0‰; Figure S4 in Supporting Information S1), while compatible with the highly positively fractionated δ 53 Cr auth record of sediments shales between 1.45 and 1.33 Ga, but lower than the shales formed in a more oxidized atmosphere between 0.8 and 0.63 Ga with the atmospheric oxygen concentration >10% (Figure S4 in Supporting Information S1; Canfield et al, 2018;Cole et al, 2016;Gilleaudeau et al, 2016; N.

“…In the ferric oxide‐rich deposits, Cr(VI) species can be reduced back to Cr(III) efficiently by Fe(II), and effectively scavenged into Fe(III)‐Cr(III) oxyhydroxides, preserving the original Cr isotopic composition of the reacted Cr(VI) (Døssing et al., 2011). Therefore, the accumulation of isotopically heavier authigenic Cr isotopes in a ferric oxide‐rich deposit could be linked to the atmospheric oxygen level in the past (W. Wei et al., 2021). The positive linear relationship between EF Fe and EF Cr values ( R 2 = 0.71, Figure S3 in Supporting Information ) implies that Cr is strongly associated with the ferric oxyhydroxide and scavenged by the ferric oxyhydroxide from water into the IF.…”

Various iron formation (IFs) document the interplay between the geosphere and the early biosphere during their co‐evolution. At the transition between the Paleo‐ and Mesoproterozoic eras, the oxidation of the atmosphere and ocean resulted in the waning of the typical marine deposited banded IFs. Here, we report the ∼1.7 Ga Yunmengshan IF at the southern margin of the North China Craton deposited in the intertidal to upper subtidal zone belonging to river delta of coastal environments. The combined REE + Y patterns and negative δ56Fe with positive δ53Cr values reveal terrestrial precipitation of iron oxide and an enhanced continental oxidative weathering at the end of Paleoproterozoic era due to increased atmospheric oxygen level. The oxygen level happened to have facilitated the early prosperity of microaerophilic Fe(II)‐oxidation bacteria on Earth's terrestrial surface, which is recorded by the coastal shallow water iron deposits globally characterized by their small scale and subaerial features.

“…The occurrence of the Mango Mn deposits in the ~1.4 Ga Ullawarra Formation in the Edmund Basin (Figure 1) is consistent with that observed in the Ilgarari Formation, and while we were unable to access unweathered material, we postulate that the stratiform Mn mineralization there is also sedimentary in origin. Widespread oxidative-driven Mn deposition in the Ilgarari Formation (1.11 Ga), and potentially in the Ullawarra Fm (1.45 Ga), thus adds to a growing collection of evidence for oxygenated surface environments at ~1.1 and 1.4 Ga (Canfield et al, 2018;Diamond & Lyons, 2018;Gilleaudeau et al, 2016;Gilleaudeau & Kah, 2015;Hardisty et al, 2017;Parnell et al, 2010Parnell et al, , 2015Sheen et al, 2018;Sperling et al, 2014;Wei et al, 2021;Zhang et al, 2018).…”

Mesoproterozoic surface oxygenation accompanied major sedimentary manganese deposition at 1.4 and 1.1 Ga

Manganese (Mn) oxidation in marine environments requires oxygen (O 2 ) or other reactive oxygen species in the water column, and widespread Mn oxide deposition in ancient sedimentary rocks has long been used as a proxy for oxidation. The oxygenation of Earth's atmosphere and oceans across the Archean-Proterozoic boundary are associated with massive Mn deposits, whereas the interval from 1.8-1.0 Ga is generally believed to be a time of low atmospheric oxygen with an apparent hiatus in sedimentary Mn deposition. Here, we report geochemical and mineralogical analyses from 1.1 Ga manganiferous marine-shelf siltstones from the Bangemall Supergroup, Western Australia, which underlie recently discovered economically significant manganese deposits. Layers bearing Mn carbonate microspheres, comparable with major global Mn deposits, reveal that intense periods of sedimentary Mn deposition occurred in the late Mesoproterozoic. Iron geochemical data suggest anoxic-ferruginous seafloor conditions at the onset of Mn deposition, followed by oxic conditions in the water column as Mn deposition persisted and eventually ceased. These data imply there was spatially widespread surface oxygenation ~1.1 Ga with sufficiently oxic conditions in shelf environments to oxidize marine Mn(II). Comparable large stratiform Mn carbonate deposits also occur in ~1.4 Ga marine siltstones hosted in underlying sedimentary units. These deposits are greater or at least commensurate in scale (tonnage) to those that followed the major oxygenation transitions from the Neoproterozoic. Such a period of sedimentary manganogenesis is inconsistent with a model of persistently low O 2 throughout the entirety of the Mesoproterozoic and provides robust evidence for dynamic redox changes in the mid to late Mesoproterozoic.

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 these happened at ∼1.4 Ga, and it is speculated that this event may link to the emplacement of large igneous province (LIP) at this time. However, direct evidence for this relationship remains to be proved. Here, we report Hg/TOC, P, and trace element concentrations across the ∼1.4 Ga oxygenation event in the Xiamaling Formation of North China. A prominent increase in Hg/TOC is slightly earlier than that of nutrient contents (especially P), pyrite and TOC abundances, suggesting that this distinct oxygenation event was likely the result of LIP activity at ∼1.4 Ga, which increased nutrient and sulfate supply from continental weathering to the ocean, sustaining elevated primary productivity, organic carbon and pyrite burial. This study indicates that LIP weathering could trigger transient oxygenation events during the mid‐Proterozoic.
