Mercury as a proxy for volcanic emissions in the geologic record
Large igneous province (LIP) eruptions are increasingly considered to have driven mass
extinction events throughout the Phanerozoic; however, uncertainties in radiometric age …

Global events of the late Paleozoic (early Devonian to Middle Permian): a review
Abstract The Late Paleozoic (Early Devonian to Middle Permian) was an interval of profound
changes in Earth-surface systems, reflected in dynamic interplay among the biosphere …

A re-assessment of elemental proxies for paleoredox analysis
Paleoredox conditions are commonly evaluated based on elemental proxies but, despite
their frequency of use, most of these proxies have received little comparative evaluation or …

Intensified continental chemical weathering and carbon-cycle perturbations linked to volcanism during the Triassic–Jurassic transition
Direct evidence of intense chemical weathering induced by volcanism is rare in sedimentary
successions. Here, we undertake a multiproxy analysis (including organic carbon isotopes …

Mercury evidence for combustion of organic-rich sediments during the end-Triassic crisis
The sources of isotopically light carbon released during the end-Triassic mass extinction
remain in debate. Here, we use mercury (Hg) concentrations and isotopes from a pelagic …

Sedimentary host phases of mercury (Hg) and implications for use of Hg as a volcanic proxy
Mercury (Hg) concentration enrichments have become a widely used proxy for volcanic
inputs to sediments, especially for investigation of ancient large igneous province (LIP) …

Mercury evidence from southern Pangea terrestrial sections for end-Permian global volcanic effects
The latest Permian mass extinction (LPME) was triggered by magmatism of the Siberian
Traps Large Igneous Province (STLIP), which left an extensive record of sedimentary Hg …

Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation
The Ordovician saw major diversification in marine life abruptly terminated by the Late
Ordovician mass extinction (LOME). Around 85% of species were eliminated in two pulses 1 …

Evidence for a prolonged Permian–Triassic extinction interval from global marine mercury records
The latest Permian mass extinction, the most devastating biocrisis of the Phanerozoic, has
been widely attributed to eruptions of the Siberian Traps Large Igneous Province, although …

[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 …
