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.

COARSE-CRYSTALLINE PYRITE OF CENTRAL TIMAN [PDF]
Минералогия, 2021 The results of mineralogical, geochemical, X-ray, isotopic and spectroscopic studies of coarse-crystalline pyrite (Kyvvozh Formation, Dimtem’el Creek, Central Timan) are presented. Pyrite is characterized by cubic habit and zonal Co distribution.

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,

A black shale protolith for gold-tellurium mineralisation in the Dalradian Supergroup (Neoproterozoic) of Britain and Ireland [PDF]
, 2017 The Dalradian Supergroup of Britain and Ireland is mineralised by gold-tellurium vein deposits. The host succession includes carbonaceous, pyritic shales (pelites) which were a source of trace elements, including gold and tellurium.

Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2023 Two examples of contact twins in pyrite from Peru are described. The first one, from Pasto Bueno ore deposit, shows the pyritohedron {120} as principal form, accompanied by the {111} octahedron and {100} cube as secondary forms, giving a lenticular aspect.

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]
, 2012 Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...

Geochemistry and metallogeny of Neoproterozoic pyrite in oxic and anoxic sediments [PDF]
, 2018 The Neoproterozoic Dalradian Supergroup contains widespread diagenetic sulphides present as pyrite. The sulphides occur in both carbonaceous shales and glacial diamictites, that were deposited in relatively reducing and oxidising conditions respectively.
