Quantifying carbon sources in the formation of authigenic carbonates at gas hydrate sites in the Gulf of Mexico
Michael J Formolo,Timothy W. Lyons,Chuanlun Zhang,Cheryl A. Kelley,Roger Sassen,Juske Horita,David R. Cole +6 more
TL;DR: This article quantified the relative contributions of dissolved carbon dioxide (ΣCO2) from a variety of sources using the carbon isotope compositions of authigenic carbonates and a simple isotopic mass balance.
Journal ArticleDOI
Sulphur isotope fractionation in modern microbial mats and the evolution of the sulphur cycle
TL;DR: It is concluded that high sulphate concentrations give rise to highly 34S-depleted sulphides, and thus that appreciable concentrations of seawater sulphate did not accumulate until the initial accumulation of oxygen into the atmosphere in post-Archaean times.

A sulfate control on marine mid-depth euxinia on the early Cambrian (ca. 529–521 Ma) Yangtze platform, South China
TL;DR: In this article, the authors report new Fe-Mo-C-S geochemical data from black shale-rich strata of the early Cambrian continental margin Yangjiaping section in the Yangtze platform, South China.
Journal ArticleDOI
A paired sulfate–pyrite δ34S approach to understanding the evolution of the Ediacaran–Cambrian sulfur cycle
TL;DR: In this paper, a high-resolution record of paired sulfate and pyrite from sediments spanning ca. 547-540 million years ago (Ma) from the Ara Group of the Huqf Supergroup, Sultanate of Oman is presented.

How sulfate-driven anaerobic oxidation of methane affects the sulfur isotopic composition of pyrite: A SIMS study from the South China Sea
Zhiyong Lin,Zhiyong Lin,Xiaoming Sun,Jörn Peckmann,Jörn Peckmann,Yang Lu,Li Xu,Harald Strauss,Haoyang Zhou,Junli Gong,Hongfeng Lu,Barbara M.A. Teichert +11 more
TL;DR: In this article, the authors applied secondary ion mass spectroscopy (SIMS) to analyze the sulfur isotope composition (δ34S) of authigenic pyrite in addition to sulfur measurements of bulk sulfide and hand-picked pyritic aggregates from two seafloor sites, HS148 and HS217, in the Shenhu seepage area, South China Sea.

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.
