The link between the Permian–Triassic mass extinction (252 million years ago) and the
emplacement of the Siberian Traps Large Igneous Province (STLIP) was first proposed in …

The end-Triassic mass extinction was one of the big five crises of the fossil record. It affected
diverse marine groups, including bivalves, brachiopods, ostracods, calcareous algae …

The end-Permian mass extinction event (∼ 252 Mya) is associated with one of the largest
global carbon cycle perturbations in the Phanerozoic and is thought to be triggered by the …

The history of Earth's biodiversity is punctuated episodically by mass extinctions. These are
characterized by major declines of taxon richness, but the accompanying ecological …

The protracted oxygenation of the ocean-atmosphere system is one of the most fundamental
changes to the Earth system through its history. The uranium isotopic composition (238 …

Although Ce anomalies are commonly used to reconstruct past seawater redox conditions,
published interpretations are based on various proxy materials and analytical approaches …

Climatic warming has been widely cited as a driver for many mass extinction events in Earth
history, including the middle-late Permian Guadalupian-Lo**ian boundary (GLB) mass …

As an important contributor to the habitability of our planet, the oxygen cycle is
interconnected with the emergence and evolution of complex life and is also the basis to …

In the modern ocean, U reduction and incorporation into anoxic sediments imparts a large
isotopic fractionation of approximately+ 0.6‰ that shifts the seawater δ 238 U value (238 …

As the parent element in the U-Pb and Pb-Pb radiochronometers, uranium (U) was one of
the first heavy elements whose isotopic composition was carefully determined. Thought to …
