Xiting Liu,Anchun Li,David A. Fike,Jiang Dong,Fangjian Xu,Guang-Chao Zhuang,Daidu Fan,Zuosheng Yang,Houjie Wang +8 more
TL;DR: In this article, a set of sulfur isotope data for hand-picked pyrites (δ34Spyr) from the coarse fraction of bulk sediments, coupled with the contents of carbonate, total organic carbon (TOC) and nitrogen (TN), as well as δ13C values of the TOC, from sediments of core EC2005 on the inner shelf of the East China Sea (ECS) since 16.4

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.
