Joining forces: Combined biological and geochemical proxies reveal a complex but refined high-resolution palaeo-oxygen history in Devonian epeiric seas
TL;DR: In this paper, two Devonian black shale intervals were analysed using a carefully integrated palaeontological-geochemical approach to interpret relative bottom water oxygen levels at a resolution and sensitivity possible only through the combined approach.

Biogeochemistry of manganese- and iron-rich sediments in Toolik Lake, Alaska
TL;DR: The sediment of Toolik Lake in arctic Alaska is characterized by extremely low rates of organic matter sedimentation and unusually high concentrations of iron and manganese as mentioned in this paper, leading to an oxidizing environment at the sediment-water interface.

The Archean komatiite-hosted, PGE-bearing Ni–Cu sulfide deposit at Vaara, eastern Finland: evidence for assimilation of external sulfur and post-depositional desulfurization
TL;DR: The Vaara sulfide mine in the Archean Suomussalmi greenstone belt as discussed by the authors is an example of a komatiite with high chalcophile element contents.

Geochemical record of methane seepage in authigenic carbonates and surrounding host sediments: A case study from the South China Sea
TL;DR: In this article, three gravity cores (D-8, D-F, and D-7) were collected from seep sites on the northern slope of the South China Sea where gas hydrates were drilled in the subsurface.

Sulphur cycling in the drinking water catchment area of Torgau–Mockritz (Germany): insights from hydrochemical and stable isotope investigations
TL;DR: In this article, the authors investigated the reasons for elevated concentrations of dissolved groundwater sulphate in the drinking water catchment area of Torgau-Mockritz (Germany) and identified the three most important anthropogenic sources of sulphate identified in this study are historic atmospheric sulphate deposition, predominantly of anthropogenic origin, inorganic fertilization, and dissolution of gypsum from waste dumps.

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.
