Temporally and spatially dynamic redox conditions on an upwelling margin: The impact on coupled sedimentary Mo and U isotope systematics, and implications for the Mo-U paleoredox proxy
Zhiwei He,Zhiwei He,Zhiwei He,Matthew O Clarkson,Morten B. Andersen,Corey Archer,Tim C. Sweere,Peter Kraal,Alex Guthauser,Fang Huang,Fang Huang,Derek Vance +11 more
TL;DR: In this paper, the authors present a comprehensive sediment-porewater Mo and U isotope study in the Benguela upwelling system off Namibia, including the first dataset incorporating coupled Mo-U abundance and isotope analysis of both solid authigenic phases and porewaters.

Guadalupian (Middle Permian) ocean redox evolution in South China and its implications for mass extinction
TL;DR: Wang et al. as mentioned in this paper presented pyrite framboid size distributions, pyritite-sulfur isotopic compositions, and C-N-S profiles for the entire Guadalupian from South China to develop a record of ocean redox evolution to help understand the selective extinction.

Nitrogen sulphur interactions in coal flames
TL;DR: In this article, the effect of sulphur on NO production in coal flames was investigated using an experimental approach and it was shown that the change in the NO emission due to SO 2 addition is dependent upon the stoichiometry of the flame and that sulphur can interact with the production of NO in a heterogeneous coal flame in a manner similar to that reported previously for gaseous and liquid fuel flames.

Tidal Marsh Restoration at Poplar Island I: Transformation of Estuarine Sediments into Marsh Soils
TL;DR: In this article, the authors show that fine-grained dredged materials from non-contaminated environments are well suited for the creation of tidal wetlands after placement and seasoning 1-2 years.
Iron speciation and isotope perspectives on palaeoproterozoic water column chemistry
Christopher T. Reinhard,Timothy W. Lyons,Olivier Rouxel,Dan Asael,Nicolas Dauphas,Lee R. Kump +5 more
TL;DR: In this paper, Reinhard et al. present a suite of Fe palaeoredox proxies, which can be used as a proxy for ancient euxinia (anoxic and H2S-rich conditions) on the local scale.

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.
