Recurrent photic zone euxinia limited ocean oxygenation and animal evolution during the Ediacaran
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 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 …

Geochemical and hydrographic evolution of the Late Devonian Appalachian Seaway: linking sedimentation, redox, and salinity across time and space
Continental interiors were flooded by epeiric seas during many intervals of the geologic
past. Few modern analogs exist for these environments, however, and basic variables such …

Mercury isotope evidence for Middle Ordovician photic-zone euxinia: Implications for termination of the Great Ordovician biodiversification event
Abstract The Darriwilian (Middle Ordovician) is marked by a striking peak of the Great
Ordovician Biodiversification Event (GOBE) followed by an abrupt∼ 50% decline in …

The expansion of land plants during the Late Devonian contributed to the marine mass extinction
The evolution and expansion of land plants brought about one of the most dramatic shifts in
the history of the Earth system—the birth of modern soils—and likely stimulated massive …

Applications of mercury stable isotopes for tracing volcanism in the geologic record
Q Gong, MX Ling, W Zheng - Science China Earth Sciences, 2024 - Springer
Mercury (Hg) enrichments in ancient sediments have been used as a proxy of volcanism,
especially large igneous province (LIP) eruptions. However, considering the existence of …

Subaerial volcanism broke mid-Proterozoic environmental stasis
The mid-Proterozoic, spanning 1.8 to 0.8 billion years ago, is recognized as a phase of
marine anoxia, low marine primary productivity (MPP), and constrained eukaryotic …

Climate-forced Hg-remobilization associated with fern mutagenesis in the aftermath of the end-Triassic extinction
The long-term effects of the Central Atlantic Magmatic Province, a large igneous province
connected to the end-Triassic mass-extinction (201.5 Ma), remain largely elusive. Here, we …
