A comprehensive sulfur and oxygen isotope study of sulfur cycling in a shallow, hyper-euxinic meromictic lake
William P. Gilhooly,William P. Gilhooly,Christopher T. Reinhard,Christopher T. Reinhard,Timothy W. Lyons +4 more
TL;DR: In this article, the isotopic composition of sulfate (δ34SSO4 and δ18OSO4), sulfide, and water column sulfate was analyzed to track the potentially coupled processes of dissimilatory sulfate reduction and phototrophic sulfide oxidation within an aquatic environment with extremely high sulfide concentrations (>30 mM).

Effect of Resuspension on the Release of Heavy Metals and Water Chemistry in Anoxic and Oxic Sediments
TL;DR: In this article, two types of river sediments with contrasting characteristics (anoxic or oxic) were resuspended and the release of heavy metals and changes in water chemistry were investigated.

Evidence for the development of local anoxia during the Cambrian SPICE event in eastern North America.
TL;DR: Whether changes in local oxygenation accompanied the onset of the SPICE in southern Laurentia using cores of the Nolichucky and Eau Claire Formations is explored, with features broadly consistent with a global expansion of anoxia playing a role in driving the isotopic trends and extinctions observed during the event.

Reconstruction of Local and Global Marine Redox Conditions During Deposition of Late Ordovician and Early Silurian Organic-Rich Mudrocks in the Siljan Ring District, Central Sweden
Xinze Lu,Brian Kendall,Chao Li,Holly J. Stein,Judith L. Hannah,Gwyneth W. Gordon,Jan Ove R. Ebbestad +6 more
TL;DR: The Siljan ring district in central Sweden was created by a bolide impact at 377±2 Ma that triggered oil generation from organic-richmudrocks (ORM) of the Late Ordovician (Katian) Fjacka Shale and/or...

Ocean redox conditions between the snowballs – Geochemical constraints from Arena Formation, East Greenland
Eva L. Scheller,Alex Dickson,Donald E. Canfield,Christoph Korte,Kasper K. Kristiansen,Tais W. Dahl +5 more
TL;DR: In this article, the authors used molybdenum (Mo), carbon (C), sulfur (S) isotopes and iron (Fe) speciation results from the Arena Fm, East Greenland, to constrain ocean redox conditions during the Cryogenian, after the Sturtian deglaciation and before the major radiation of animals.

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.

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.
