High-frequency fluctuations in redox conditions during the latest Permian mass extinction
TL;DR: In this article, high-resolution geochemical and sedimentological data from Fiskegrav, East Greenland, reveal fluctuations in marine redox conditions associated with the final disappearance of bioturbating organisms during the latest Permian mass extinction.
19. a comparative study of diagenetic pathways in sediments of the caribbean sea: highlights from pore-water results 1
TL;DR: The results of Leg 165 of the Ocean Drilling Program as mentioned in this paper reveal varying proportions of reactive carbonate species, a labile volcanic ash fraction occurring in discrete layers and as a dispersed component, and detrital fluxes derived from continental weathering.
Journal ArticleDOI
Coulometric determination of total sulfur and reduced inorganic sulfur fractions in environmental samples.
TL;DR: A coulometric titration method is presented and evaluated for total sulfur, acid-volatile sulfide (AVS), chromium-reducible sulfur (CRS), and extractable-sulfate in standard reference materials and sediment samples from a contaminated site.

Seasonal variations of arsenic at the sediment–water interface of Poyang Lake, China
TL;DR: In this paper, porewater profiles and sediment phase data were collected from Poyang Lake, and the main geochemical behavior of As was controlled by adsorption/desorption, precipitation and molecular diffusion.

The impact of diffusive transport of methane on pore-water and sediment geochemistry constrained by authigenic enrichments of carbon, sulfur, and trace elements: A case study from the Shenhu area of the South China Sea
TL;DR: In this article, the authors investigated carbon, sulfur, and trace element geochemistry of pore-water and sediments at a site affected by upward methane diffusion in the Shenhu area of the South China Sea, where the sulfate-methane transition zone (SMTZ) is located ~7.6m below the seafloor based on sulfate and methane concentrations.

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.
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.
