Mineralization, alteration, and hydrothermal metamorphism of the ophiolite-hosted Turner-Albright sulfide deposit, southwestern Oregon
Robert A. Zierenberg,Wayne C. Shanks,William E. Seyfried,Randolph A. Koski,Michael D. Strickler +4 more
TL;DR: The Turner-Albright sulfide deposit, part of the Josephine ophiolite, formed on and below the seafloor during Late Jurassic volcanism at a back arc spreading center.

Reconstruction of paleo-redox conditions and early sulfur cycling during deposition of the Cryogenian Datangpo Formation in South China
TL;DR: In this paper, the authors used multi-geochemical proxies, including different iron speciation and relevant ratios (Fe HR /Fe T, Fe P /Fe HR and Fe T /Al ratios) and molybdenum concentrations, to reconstruct the paleo-depositional environment of the Datangpo black shale horizon.

Chemical speciation of sulfur compounds in surface sediments from three bays (Fresnaye, Seine and Authie) in northern France, and identification of some factors controlling their generation
TL;DR: It has been found that reactive iron scavenges the most part of the generated sulfide as a result of a particularly activated sulfate reduction by bacterial activities, which explains the increase of the built-up of dissolved reduced sulfur in the interstitial waters as well as the existence of elemental sulfur and polysulfides that permit the conversion of FeS into FeS(2).

Sulfur diagenesis and partitioning in Holocene Peru shelf and upper slope sediments
Neil S. Suits,Michael A. Arthur +1 more
TL;DR: Sediments of the Peru margin were sampled in two transects across the shelf and upper slope (75 to 1000 m) in October of 1992 as mentioned in this paper, and the results showed that organic carbon (TOC) concentrations in surface sediments range from 1 to 18% on a dry weight basis.

Multiple sulfur isotope composition of oxidized Samoan melts and the implications of a sulfur isotope ‘mantle array’ in chemical geodynamics
TL;DR: In this article, the authors reported new data for sulfur and copper abundances, S speciation and multiple S isotopic compositions (32S, 33S, 34S, 36S) in 15 fresh submarine basaltic glasses from the Samoan archipelago, which defines the enriched-mantle-2 (EM2) endmember.

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.
