[HTML][HTML] Tracing volcanic emissions from the Central Atlantic Magmatic Province in the sedimentary record
The end-Triassic mass extinction (ETME) is thought to have been caused by voluminous,
pulsed volcanic activity of the Central Atlantic Magmatic Province (CAMP). Over the last …

Knowledge gaps and missing links in understanding mass extinctions: Can mathematical modeling help?
Extinction of species, and even clades, is a normal part of the macroevolutionary process.
However, several times in Earth history the rate of species and clade extinctions increased …

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 …

The Triassic–Jurassic transition–A review of environmental change at the dawn of modern life
Abstract The Triassic–Jurassic transition, which is here broadly defined as extending from
the Late Triassic through the Early Jurassic (~ 237 Ma to 174 Ma), was an important interval …

High temperature methane emissions from Large Igneous Provinces as contributors to late Permian mass extinctions
Methane (CH4) emissions induced by Large Igneous Provinces have the potential to
contribute to global environmental changes that triggered mass extinctions in Earth's history …

Massive methane fluxing from magma–sediment interaction in the end-Triassic Central Atlantic Magmatic Province
Exceptional magmatic events coincided with the largest mass extinctions throughout Earth's
history. Extensive degassing from organic-rich sediments intruded by magmas is a possible …

[HTML][HTML] New high precision U-Pb ages and Hf isotope data from the Karoo large igneous province; implications for pulsed magmatism and early Toarcian …
To better constrain the age and duration of the magmatism associated with the Karoo large
igneous province (LIP), we present new U-Pb ID-TIMS dates and εHf values from …
