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 …

Widespread oceanic anoxia marked by globally extensive deposition of organic-rich black
shale during the Late Devonian was a major factor in the mass extinctions at the Frasnian …

Abstract The Late Devonian records one of the most dramatic series of taxonomic and
ecological turnovers in the history of life. The precise controls over the elevated extinctions …

Abstract The Ediacaran Period (~ 635–539 Ma) is marked by the emergence and
diversification of complex metazoans linked to ocean redox changes, but the processes and …

The South China Craton experienced large changes in climate, eustasy and environmental
conditions during the Late Ordovician Hirnantian Ice Age, but their impact on the watermass …

Salinity, a key property of watermasses, is difficult to reconstruct in paleodepositional
systems, and errors in assigning salinity facies to epicratonic and marginal-marine deposits …

Abstract The middle Paleozoic (∼ 420-350 Myr) records a major increase in ocean-
atmosphere oxygen levels; however, the timing and pattern of oxygenation are poorly …

Ancient epicratonic formations, which represent the bulk of pre-Jurassic sedimentary rocks,
have been widely interpreted as marine deposits, but recently developed bulk-shale …

Although elemental proxies (ie, boron/gallium [B/Ga], strontium/barium [Sr/Ba], and
sulfur/total organic carbon [S/TOC]) have been extensively used to evaluate paleo …

Mercury (Hg) concentrations and isotopes are widely used as proxies for volcanic inputs to
paleodepositional systems. Enhanced volcanism during the Late Devonian was previously …
