TL;DR: The early Triassic is generally portrayed as a time of various, high ecological stresses leading to a delayed biotic recovery after the devastating end-Permian mass extinction.

Natural zinc enrichment in peatlands: Biogeochemistry of ZnS formation
TL;DR: In this article, the authors examined the biogeochemical mechanisms involved in zinc retention and accumulation in a metalliferous peatland of western New York and found that zinc sulfides occurred as framboidal aggregates of sphalerite and polytypic wurtzite associated with bacterial cells and organic matter.

TL;DR: The results suggest that manganese oxide burial was near or even greater than modern burial fluxes, which is likely linked to an expansion of oxic conditions in the global oceans during the Shuram NCIE.

TL;DR: In this paper, the authors apply multi-proxy geochemical analyses (Fe speciation, δ13C and δ15N) to exceptionally well-preserved shales from the approximately 2.7 billion year old Manjeri Formation in the Belingwe Greenstone Belt, Zimbabwe, to evaluate the redox status of Earth's early nitrogen cycle and decipher feedbacks associated with the initial stages of planetary oxygenation.

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.

Journal ArticleDOI
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.
