Trace metal behaviour in riverine sediments: Role of organic matter and sulfides
Adeline Charriau,Ludovic Lesven,Yue Gao,Martine Leermakers,Willy Baeyens,Baghdad Ouddane,Gabriel Billon +6 more
TL;DR: In this article, three sediment cores were collected in the Scheldt, Lys and Spiere canals, which drain a highly populated and industrialized area in Western Europe, and the speciation and the distribution of trace metals in pore waters and sediment particles were assessed through a combination of computational and experimental techniques.

Clara L. Blättler,Mark Claire,Anthony R. Prave,Kalle Kirsimäe,John A. Higgins,P. Medvedev,A.E. Romashkin,Dmitry V. Rychanchik,Aubrey L. Zerkle,Kärt Paiste,Timmu Kreitsmann,Ian L. Millar,Justin A. Hayles,Huiming Bao,Alexandra V. Turchyn,Matthew R. Warke,Aivo Lepland +16 more
TL;DR: These results show that substantial amounts of surface oxidant accumulated during this critical transition in Earth’s oxygenation, and provide a constraint on the magnitude and timing of early Earth's response to the Great Oxidation Event 2.3 billion years ago.

A global transition to ferruginous conditions in the early Neoproterozoic oceans
Romain Guilbaud,Romain Guilbaud,Simon W. Poulton,Nicholas J. Butterfield,Maoyan Zhu,Graham A. Shields-Zhou +5 more
TL;DR: In this article, the authors report an analysis of ocean redox conditions throughout the Proterozoic using new and existing iron speciation and sulphur isotope data from multiple cores and outcrops.

Pyrite multiple-sulfur isotope evidence for rapid expansion and contraction of the early Paleoproterozoic seawater sulfate reservoir
Clint Scott,Boswell A. Wing,Andrey Bekker,Andrey Bekker,Noah J. Planavsky,Pavel Medvedev,Steven M Bates,Misuk Yun,Timothy W. Lyons +8 more
TL;DR: In this article, a study of pyrite multiple-sulfur isotopes from early Paleoproterozoic black shales is presented, supported by Fe speciation and organic carbon isotopes.

Doreen A. Zaback,Lisa M. Pratt +1 more
TL;DR: Isotopic compositions of six sulfur species (acid-volatile, disulfide, kerogen, bitumen, sulfate and elemental) have been studied in the Miocene Monterey Formation, Santa Maria Basin (onshore), California.

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.
