Massive perturbations to atmospheric sulfur in the aftermath of the Chicxulub impact
Christopher K. Junium,Aubrey L. Zerkle,James D. Witts,Linda C. Ivany,Thomas E. Yancey,Chengjie Liu,Mark Claire +6 more
TL;DR: In this paper , the sulfur isotope anomalies are confined to beds containing ejecta and, in the immediately overlying sediments, are temporally unrelated to known episodes of volcanism that also bracket this event, further addressing the controversial role of the Deccan Traps in the extinction.

Multiple S-isotopic constraints on paleo-redox and sulfate concentrations across the Ediacaran-Cambrian transition in South China
Dandan Li,Xiaolin Zhang,Xiaolin Zhang,Dongping Hu,Da Li,Guijie Zhang,Xu Zhang,Hong-Fei Ling,Yilun Xu,Yanan Shen,Yanan Shen +10 more
TL;DR: In this paper, multiple S-isotopic compositions of pyrite (δ34Spy and Δ33Spy) from the Xiaotan section spanning the Ediacaran-Cambrian transition interval in South China are presented.

Origin and evolution of atmospheric xenon and other noble gases : geodynamical and atmospheric implications
TL;DR: The origin and evolution of l'atmosphere terrestre demeure enigmatique as discussed by the authors, i.e., it is difficult to define its origin and its evolution.

False negatives for remote life detection on ocean-bearing planets: Lessons from the early Earth
TL;DR: In this article, the authors summarize recent developments from geochemical proxy records and Earth system models that provide insight into the long-term evolution of the most readily detectable potential biosignature gases on Earth -oxy(O2), ozone (O3), and methane (CH4), and suggest that the canonical O2-CH4 disequilibrium biosignatures would perhaps have been challenging to detect remotely during Earth's ~45 billion year history and that in general atmospheric O2/O3 levels have been a poor proxy for the presence of Earth's biosphere for all but

Geochemistry of Hydrothermal Ore Deposits
TL;DR: In this paper, Skinner et al. discuss the relationship between hydrous alteration and its relationship to hydrous fluid composition in the formation of sulfide-sulfide ores.

Sedimentary pyrite formation: An update
TL;DR: In this article, it was shown that organic matter appears to be the major control on pyrite formation in normal (non-euxinic) terrigenous marine sediments where dissolved sulfate and iron minerals are abundant.
Journal ArticleDOI
The age curves of sulfur and oxygen isotopes in marine sulfate and their mutual interpretation
TL;DR: In this article, a model involving symmetrical fluxes is introduced to take advantage of the oxygen data, and the measured δ34S and δ18O correspond to variations in these isotopes in sulfate of the world ocean surface.
