Oceanic anoxic events, photic-zone euxinia, and controversy of sea-level fluctuations during the Middle-Late Devonian
This paper reviews global records of anoxic events of the Middle Devonian–earliest
Mississippian, as well as the possible triggers and controls of these events. These “anoxic …

The role of LIPs in Phanerozoic mass extinctions: An Hg perspective
Abstract All of the Big Five mass extinctions (BFMEs) of the Phanerozoic are postulated to
have been associated with eruptions of large igneous provinces (LIPs), although the role of …

[HTML][HTML] A volcanic scenario for the Frasnian–Famennian major biotic crisis and other Late Devonian global changes: more answers than questions?
G Racki - Global and Planetary Change, 2020 - Elsevier
Although the prime causation of the Late Devonian Frasnian–Famennian (F–F) mass
extinction remains conjectural, such destructive factors as the spread of anoxia and rapid …

[HTML][HTML] Effects of redox variability and early diagenesis on marine sedimentary Hg records
Volcanism is a dominant natural source of mercury (Hg) to the atmosphere, biosphere,
ocean and sediments. In recent years, sedimentary Hg contents have emerged as a tool to …

Basin-scale reconstruction of euxinia and Late Devonian mass extinctions
Abstract The Devonian–Carboniferous transition marks a fundamental shift in the surface
environment primarily related to changes in ocean–atmosphere oxidation states,, resulting …

Volcanic related methylmercury poisoning as the possible driver of the end-Devonian Mass Extinction
Abstract The end-Devonian global Hangenberg event (359 Ma) is among the most
devastating mass extinction events in Earth's history, albeit not one of the “Big Five”. This …

[HTML][HTML] Depositional environments and source rock potential of some Upper Palaeozoic (Devonian) coals on Bjørnøya, Western Barents shelf
Upper Palaeozoic strata are potential sources for hydrocarbon plays on the Norwegian

Uranium and molybdenum isotope evidence for globally extensive marine euxinia on continental margins and in epicontinental seas during the Devonian …
Abstract The end-Devonian Hangenberg Crisis was one of the biggest Phanerozoic mass
