Carbon-sulfur-iron systematics of the uppermost deep-water sediments of the Black Sea
TL;DR: In this article, carbon-sulfur relationships (evaluated on a calcium carbonate-free basis to avoid spurious correlations resulting from dilution effects) demonstrate that organic carbon and pyrite-S are essentially decoupled.

An emerging picture of Neoproterozoic ocean chemistry: Insights from the Chuar Group, Grand Canyon, USA
David T. Johnston,Simon W. Poulton,Carol M. Dehler,Susannah M. Porter,Jon M. Husson,Donald E. Canfield,Andrew H. Knoll +6 more
TL;DR: In this article, a detailed analysis of the > 742 million year old Chuar Group reveals a marine basin dominated by anoxic and ferrous iron-rich bottom waters punctuated, late in the basin's development, by an intrusion of sulfide-rich (euxinic) conditions.

Sulfate-reducing bacteria and their activities in cyanobacterial mats of Solar Lake (Sinai, Egypt)
Andreas P Teske,Niels B. Ramsing,Kirsten Silvia Habicht,Manabu Fukui,Jan Küver,Bo Barker Jørgensen,Yehuda Cohen +6 more
TL;DR: In this article, the sulfate reducing bacteria within the surface layer of the hypersaline cyanobacterial mat of Solar Lake (Sinai, Egypt) were investigated with combined microbiological, molecular, and biogeochemical approaches.

Changes in Type II Kerogen Density as a Function of Maturity: Evidence from the Kimmeridge Clay Formation
TL;DR: In this paper, the authors purified 26 samples of the Kimmeridge Clay Formation over the full range of maturities pertinent to petroleum generation, and found that most samples comprised >90% amorphous organic matter (AOM).

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.
Journal ArticleDOI
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.
