Weathering, alteration and reconstructing Earth's oxygenation.
TL;DR: An analysis of a large shale geochemistry database reveals significant differences in cerium (Ce) anomalies, a common palaeoredox proxy, between outcrop and drill core samples, providing support for the idea that geochemical data from altered samples are frequently published in the peer-reviewed literature.
Journal ArticleDOI
Automatic mechanism generation for pyrolysis of di-tert-butyl sulfide
TL;DR: The concerted unimolecular decomposition of di-tert- butyl sulfide to form isobutene and tert-butyl thiol was found to be a key reaction in both cases, as it explained the first-order sulfide decomposition.

TL;DR: It is concluded that this iron isotope systematic derives from microbial respiration of iron oxides during early diagenesis, extending the geological record of dissimilatory iron reduction back more than 560 million years and confirming that micro‐organisms closely related to the last common ancestor had the ability to reduce Fe(III).

Multiple sulfur-isotopic evidence for a shallowly stratified ocean following the Triassic-Jurassic boundary mass extinction
Genming Luo,Genming Luo,Sylvain Richoz,Sylvain Richoz,Bas van de Schootbrugge,Thomas J. Algeo,Thomas J. Algeo,Shucheng Xie,Shuhei Ono,Roger E. Summons +9 more
TL;DR: The cause of the Triassic-Jurassic boundary biotic crisis, one of the ‘Big Five’ mass extinctions of the Phanerozoic, remains controversial as discussed by the authors.

A multistage origin for Neoarchean layered hematite-magnetite iron formation from the Weld Range, Yilgarn Craton, Western Australia
Andrew D. Czaja,Andrew D. Czaja,Martin J. Van Kranendonk,Martin J. Van Kranendonk,Brian L. Beard,Brian L. Beard,Clark M. Johnson,Clark M. Johnson +7 more
TL;DR: In this article, the authors describe a formation pathway for an Algoma-type banded iron formation (BIF) from the 2.75 billion-year-old Weld Range of Western Australia, based on petrographic and Fe isotope analyses of drill core samples.

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.
Journal ArticleDOI
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.
