The Palaeozoic–Mesozoic transition is marked by distinct perturbations in the global carbon
cycle resulting in a prominent negative carbon-isotope excursion at the Permian–Triassic (P …

The sedimentological and geochemical expression of Mesozoic ocean anoxic events
(OAEs) in the geologic record is reasonably well-characterized and the causal mechanisms …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

The latest Permian mass extinction (LPE), just prior to the Permian–Triassic boundary at~
252Ma, resulted in the disappearance of~ 90% of skeletonized marine taxa and the …

Recovery from the end-Permian mass extinction is frequently described as delayed,,, with
complex ecological communities typically not found in the fossil record until the Middle …

Carbon cycle disturbance associated with mass extinction at the end of the Permian Period
continued through the Early Triassic, an interval of approximately 5 million years …

The end-Permian mass extinction horizon is marked by an abrupt shift in style of carbonate
sedimentation and a negative excursion in the carbon isotope (δ 13C) composition of …

Vertical gradients in the δ13C of seawater dissolved inorganic carbon (Δδ13CDIC) can be
estimated for paleomarine systems based on δ13Ccarb data from sections representing a …

The history of the Earth system is a story of change. Some changes are gradual and benign,
but others, especially those associated with catastrophic mass extinction, are relatively …

Based on analyses of single, thermally annealed and chemically abraded zircons, a new
high-precision U–Pb age of 251.22±0.20 Ma is established for a volcanic ash layer within …
