Christian März,Christian März,Thomas Wagner,Thomas Wagner,S. Aqleh,M. Al-Alaween,S. van den Boorn,Olaf G. Podlaha,Sadat Kolonic,Simon W. Poulton,Bernhard Schnetger,Hans-Juergen Brumsack +11 more
TL;DR: In this article, the authors studied organic-rich Eocene marls and limestones (oil shale) from the central Jordan Amzaq-Hazra subbasin, part of a Cretaceous-Paleogene shelf system along the southern Neo-Tethys margin.

Porewater sulphur geochemistry and fossil preservation during phosphate diagenesis in a Lower Cretaceous shelf mudstone
TL;DR: Lower Cretaceous mudstones exposed at Speeton in North Yorkshire, UK, contain lobsters and burrows preserved in diagenetic phosphate concretions as discussed by the authors, which can be explained by the action of bioturbating macrofauna; the introduction of oxygen in ventilating seawater results in the oxidation of early formed isotopically light pyrite, resulting in porewater sulphate that is enriched in 32S.

Investigations on pyrite oxidation in mine spoils of the Lusatian lignite mining district
TL;DR: In this article, the impact of organic waste material and fly ash on microbial and chemical pyrite oxidation was investigated in a field experiment, as well as in column tests under laboratory conditions.

Small-scale heterogeneity in the geochemistry of seagrass vegetated and non-vegetated estuarine sediments: causes and consequences
TL;DR: In this paper, solid-state microelectrodes were used to investigate dissolved and solid phase chemical parameters in eelgrass vegetated and nearby non-vegetated sediments to determine their vertical, lateral, and temporal distributions.

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.
