SO 2 photolysis as a source for sulfur mass-independent isotope signatures in stratospehric aerosols
TL;DR: In this article, a series of laboratory photochemical experiments were carried out to investigate the effect of temperature and added O2 on the S-MIF produced by two absorption band systems of SO2: photolysis in the 190 to 220 nm region and photoexcitation in the 250 to 350 nm region.

Open system sulphate reduction in a diagenetic environment – Isotopic analysis of barite (δ34S and δ18O) and pyrite (δ34S) from the Tom and Jason Late Devonian Zn–Pb–Ba deposits, Selwyn Basin, Canada
J M Magnall,Sarah A. Gleeson,Richard A. Stern,Robert J. Newton,Simon W. Poulton,Suzanne Paradis +5 more
TL;DR: In this paper, the paragenetic relationship between barite, pyrite and hydrothermal base metal sulphides has been determined using transmitted and reflected light microscopy, and backscatter electron imaging.

TL;DR: In this article, an integrated study of iron speciation, redox-sensitive trace elements, and Mo isotopes (δ 98 Mo) on the black shale interval of the lower Cambrian Hetang Formation (∼535-521 ǫ) at Lantian, South China, was conducted.

Massive developments of microbial mats following phytoplankton blooms in a naturally eutrophic bay: Implications for nitrogen cycling
TL;DR: In this paper, the authors studied the consequences of phytodetrital deposition and oxygen deficiency on the environment and benthic communities in Concepcion Bay and found that NH4 exchange showed a clear seasonal pattern, with influxes during the winter (7.6 4.9 mmol m 2 d 1, which accounts for 17% of the total NH4 efflux during the summer period (January and March).

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.
