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.

Fluid-induced metamorphism and anatexis of refractory Ni-Co-Cu sulphides in subduction-related rocks [PDF]
E3S Web of Conferences, 2019 The role of metamorphism on refractory sulfides is not well constrained. Although experiments have displayed the effectiveness of high grade metamorphism, namely granulite facies metamorphism, on sulfide anatexis, its role in the presence of other ...

On the issue of establishing the type of coal seams by «reduction» («oxidation») of fossil coals
Технічна інженерія, 2022 The yield of volatile substances during the thermal decomposition of coals and the oxygen content in the organic mass do not unambiguously characterize both the types of coals according to the expected reduction, and the manifestations of the hazardous ...
