The Morphological Characteristics of Authigenic Pyrite Formed in Marine Sediments
Journal of Marine Science and Engineering, 2022 Pyrites are widely distributed in marine sediments, the morphology of which is applied as a proxy to infer the redox conditions of bottom water, and identify diagenetic stages and hydrocarbon leakage activities.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Advances in depressants used for pyrite flotation separation from coal/minerals
International Journal of Coal Science & Technology, 2022 Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite is affected by many factors, causing it to easily enter the concentrate and consequently reduce the quality of concentrate.

Strong local, not global, controls on marine pyrite sulfur isotopes
Science Advances, 2021 Local to regional depositional environment controls the S-isotopic composition of sedimentary pyrite. Understanding variation in the sulfur isotopic composition of sedimentary pyrite (δ34Spyr) is motivated by the key role of sulfur biogeochemistry in ...

Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone
Nature Communications, 2021 Sulfur cycling is ubiquitous in sedimentary environments, where it mediates organic carbon remineralization, impacting both local and global redox budgets, and leaving an imprint in pyrite sulfur isotope ratios (δ34Spyr).

Pore Characterization of Pyrite in the Longmaxi Formation Shale in the Upper Yangtze Area of China
Frontiers in Earth Science, 2022 Pyrite is widely distributed in the Longmaxi marine shale in the Upper Yangtze area of China. Pyrite, one of the important components of shale, has an important influence on the enrichment of shale gas.

Origin of pyrite nodules at the top of the nantuo diamictites, Southern China
Scientific Reports, 2021 Pyrite nodules up to 20 cm in diameter are found at the top of the Marinoan (~ 635 Ma) Nantuo glacial diamictite as well as in the cap dolostones and shale/siltstones in the lower Doushantuo Formation in eastern Guizhou, southern China. Field occurrences,
