“…1). Presences of detrital pyrite and uraninite in the lower units of the Huronian Supergroup suggest low O 2 levels in the atmosphere at the time of deposition 1 ; meanwhile, both presence of redbeds and disappearance of mass-independent fractionation in sulphur in the upper units suggest that a significant rise in atmospheric O 2 would have occurred around the second glaciation in the Huronian Supergroup 1,8 (Fig. 1a).…”

“…E arth's atmosphere is suggested to have shifted from anoxic to oxic in early Palaeoproterozoic during ~2.45-2.2 billion years ago (Ga) [1][2][3][4][5][6][7][8] . Any increase in O 2 would have resulted in reduced atmospheric methane levels, triggering glaciations 2 .…”

Osmium evidence for synchronicity between a rise in atmospheric oxygen and Palaeoproterozoic deglaciation

Early Palaeoproterozoic (2.5-2.0 billion years ago) was a critical phase in Earth's history, characterized by multiple severe glaciations and a rise in atmospheric o 2 (the Great oxidation Event). Although glaciations occurred at the time of o 2 increase, the relationship between climatic and atmospheric transitions remains poorly understood. Here we report high concentrations of the redox-sensitive element os with high initial 187 os/ 188 os values in a sandstone-siltstone interval that spans the transition from glacial diamictite to overlying carbonate in the Huronian supergroup, Canada. Together with the results of Re, mo and s analyses of the sediments, we suggest that immediately after the second Palaeoproterozoic glaciation, atmospheric o 2 levels became sufficiently high to deliver radiogenic continental os to shallow-marine environments, indicating the synchronicity of an episode of increasing o 2 and deglaciation. This result supports the hypothesis that climatic recovery from the glaciations acted to accelerate the Great oxidation Event.

“…In Canada, the ca. 2.4-2.2 Ga Huronian Supergroup records three glaciations (Crowell, 1999;Young et al, 2001). Deposits of the 600-1700 m thick Gowganda Formation are the youngest and most widespread, covering at least 400 200 km, with correlates elsewhere in North America.…”

Secular changes in sedimentation systems and sequence stratigraphy

________________________________________________________________________The ephemeral nature of most sedimentation processes and the fragmentary character of the sedimentary record are of first-order importance. Despite a basic uniformity of external controls on sedimentation resulting in markedly similar lithologies, facies, facies associations and depositional elements within the rock record across time, there are a number of secular changes, particularly in rates and intensities of processes that resulted in contrasts between preserved Precambrian and Phanerozoic successions. Secular change encompassed (1) variations in mantle heat, rates of plate drift and of continental crustal growth, the gravitational effects of the Moon, and in rates of weathering, erosion, transport, deposition and diagenesis;(2) a decreasing planetary rotation rate over time; (3) no vegetation in the Precambrian, but prolific microbial mats, with the opposite pertaining to the Phanerozoic; (4) the long-term evolution of the hydrosphere-atmosphere-biosphere system. A relatively abrupt and sharp turning point was reached in the Neoarchaean, with spikes in mantle plume flux and tectonothermal activity and possibly concomitant onset of the supercontinent cycle. Substantial and irreversible change occurred subsequently in the Palaeoproterozoic, whereby the dramatic change from reducing to oxidising volcanic gases ushered in change to an oxic environment, to be followed at ca. 2.4-2.3 Ga by the "Great Oxidation Event" (GOE); rise in atmospheric oxygen was accompanied by expansion of oxygenic photosynthesis in the cyanobacteria. A possible global tectono-thermal "slowdown" from ca. 2.45-2.2 Ga may have separated a preceding plate regime which interacted with a higher energy mantle from a ca. 2.2-2.0 Ga Phanerozoicstyle plate tectonic regime; the "slowdown" period also encompassed the first known global-scale glaciation and overlapped with the GOE. While large palaeodeserts emerged from ca. 2.0 -1.8 Ga, possibly associated with the evolution of the supercontinent cycle, widespread euxinia by ca. 1.85 Ga

“…These 2442-Ma rocks show a transition from MIF to mass-dependently fractionated sulfur isotopes (Reuschel et al, 2008); thus, they offer new constraints on the S-isotope cycle at the dawn of the GOE. Moreover, isotope geochemistry of marine carbonate rocks interbedded with shales may represent a robust proxy for the global carbon cycle prior to the Huronian-age glaciation (Young et al, 2001). Huronian-age global glaciation.…”

With support of the International Continental Scientific Drilling Program (ICDP) and other funding organizations, the Fennoscandia Arctic Russia – Drilling Early Earth Project (FAR-DEEP) operations have been successfully completed during 2007. A total of 3650 meters of core have been recovered from fifteen holes drilled through sedimentary and volcanic formations in Fennoscandia (Fig. 1), recording several global environmental changes spanning the time interval 2500–2000 Ma, including the Great Oxidation Event (GOE) (Holland, 2002). The core was meanwhile curated and archived in Trondheim, Norway, and it has been sampled by an international team of scientists
