Atmospheric sulfur rearrangement 2.7 billion years ago: evidence for oxygenic photosynthesis.
Florian Kurzweil,Mark Claire,Christophe Thomazo,Marc Peters,Mark D. Hannington,Harald Strauss +5 more
TL;DR: In this paper, the authors present multiple sulfur isotopes for 2.71 Ga pyritic black shales derived from the Kidd Creek area, Ontario, Canada, and show that these samples display high positive Δ33S values up to 3.8 and the typical late Archean slope in Δ36S/Δ33S of −0.9.

Early diagenetic behaviour of selenium in freshwater sediments
TL;DR: The vertical distributions of dissolved Se species [Se(IV), Se(VI) and organic Se] and diagenetic constituents [Fe(II) and Mn(II)] were obtained in porewater samples of two Sudbury area lakes (Clearwater and McFarlane).
Journal ArticleDOI
Weak coupling between sulfate reduction and the anaerobic oxidation of methane in methane-rich seafloor sediments during ex situ incubation
TL;DR: The authors investigated coupling between sulfate reduction (SR) and anaerobic oxidation of methane (AOM) by quantifying pore water geochemical profiles, determining rates of microbial processes, and examining microbial community structure at two sites within Mississippi Canyon lease block 118 (MC118) in the Northern Gulf of Mexico.

Isotopic evidence for oxygenated Mesoarchaean shallow oceans
Benjamin Eickmann,Benjamin Eickmann,Axel Hofmann,Martin Wille,Martin Wille,Thi Hao Bui,Boswell A. Wing,Boswell A. Wing,Ronny Schoenberg +8 more
TL;DR: In this article, the authors present multiple sulfur and iron isotope data of early diagenetic pyrites from 2.97-Gyr-old stromatolitic dolomites deposited in a tidal flat environment of the Nsuze Group, Pongola Supergroup, South Africa.
Journal ArticleDOI
A hydrogeochemical transport model for an oxidation experiment with pyrite/calcite/exchangers/organic matter containing sand.
TL;DR: In this article, the authors report the hydrogeochemical modeling of a complicated suite of reactions that take place during the oxidation of pyrite in a marine sediment, including dissolution of calcite, cation and proton exchange, and CO2 sorption.

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 Sulfur Cycle
TL;DR: The authors' model of the sulfur cycle can draw some conclusions that man is now contributing about one half as much as nature to the total atmospheric burden of sulfur compounds, but by A.D. 2000 he will be contributing about as much, and in the Northern Hemisphere alone he is more than matching nature.

Pyrite: Its Rapid Formation in a Salt Marsh and Its Importance In Ecosystem Metabolism
TL;DR: Pyrite formation in salt-marsh peat occurs more rapidly than is generally thought for any natural system, and the rates of sulfate reduction and ecosystem respiration may be grossly underestimated.
Book
Rock and mineral analysis
TL;DR: In this paper, the authors provide an up-to-date treatment of the problems associated with the analysis of geological materials, including the requesite steps from selection of the sample and choice of elements to the facilities needed, preparation of sample, methods for the determination of individual constituens and reporting of the results of the analysis.
