Large sulphur isotopic perturbations and oceanic changes during the Frasnian–Famennian transition of the Late Devonian
Daizhao Chen,Jianguo Wang,Grzegorz Racki,Hua Li,Cheng-Yuan Wang,Xueping Ma,Michael T. Whalen +6 more
TL;DR: The Frasnian-Famennian transition of the Late Devonian was one of the most critical intervals in the Phanerozoic. as discussed by the authors showed that large increases in continental nutrient fluxes, and subsequent primary productivity and organic burial, could have greatly enhanced bacterial sulphate reduction, producing excessive sulphide through the water columns owing to iron depletion.

Upper Holocene Sediments of the Black Sea: Summary of Leg 4 Box Cores (1988 Black Sea Oceanographic Expedition)
TL;DR: The most recent R/V Knorr Black Sea Oceanographic Expedition as mentioned in this paper revealed a wide range of uppermost Holocene sedimentary facies sampled over a broad region of the southern basin, including cores from two transects across the intersection of the water column oxic/anoxic interface with the basin-margin substrate.

Two pulses of oceanic environmental disturbance during the Permian–Triassic boundary crisis
Jun Shen,Qinglai Feng,Thomas J. Algeo,Thomas J. Algeo,Chao Li,Noah J. Planavsky,Lian Zhou,Mingliang Zhang +7 more
TL;DR: Pyrite morphology, iron speciation, and pyrite sulfur isotope data from the Xiakou section (Hubei Province, South China) were integrated to explore oceanic environmental variations through the Permian-Triassic transition and their possible relations to the largest mass extinction in Earth history as mentioned in this paper.

Integrated carbon, sulfur, and nitrogen isotope chemostratigraphy of the Ediacaran Lantian Formation in South China: Spatial gradient, ocean redox oscillation, and fossil distribution
Wei Wang,Wei Wang,C. Guan,Chuanming Zhou,Yongbo Peng,Lisa M. Pratt,X. Chen,L. Chen,Zhe Chen,Xunlai Yuan,Shuhai Xiao +10 more
TL;DR: The authors' data confirm a large (>10‰) spatial gradient in δ13 Ccarb in the lower Doushantuo/Lantian formations, but this gradient is probably due to the greater sensitivity of carbonate-poor deep-water sediments to isotopic mixing with 13 C-depleted carbonate cements, and suggests ocean redox stratification.

Oxygen, climate and the chemical evolution of a 1400 million year old tropical marine setting
Xiaomei Wang,Shuichang Zhang,Huajian Wang,Christian J. Bjerrum,Emma U. Hammarlund,Emma R. Haxen,Jin Su,Yu Wang,Donald E. Canfield +8 more
TL;DR: The Xiamaling Formation is an exceptionally well-preserved sedimentary succession deposited on a marine passive margin about 1400 million years ago as mentioned in this paper, and it can be divided into six units based on both sedimentological and geochemical criteria.

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.
