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 latest Permian mass extinction (LPME) coincided with major changes in the composition
of marine plankton communities, yet little is known about concurrent changes in primary …

Sedimentary records from the northwest margin of Pangea and the Tethys show
anomalously high Hg levels at the latest Permian extinction boundary. Background δ202Hg …

In the Precambrian, reverse weathering—a process consuming oceanic silica, metal cations
and alkalinity to form marine clays—was a key control of the long-term carbon cycle …

Ocean acidification triggered by Siberian Trap volcanism was a possible kill mechanism for
the Permo-Triassic Boundary mass extinction, but direct evidence for an acidification event …

A sedimentary record from the Buchanan Lake section, Canadian High Arctic, shows
anomalous high levels of mercury (Hg) during the latest Permian extinction (LPE) on …

Previous studies of the end-Permian mass extinction have established that it was
geologically rapid, but condensed sections have made it difficult to establish the exact timing …

Understanding variation in the sulfur isotopic composition of sedimentary pyrite (δ34Spyr) is
motivated by the key role of sulfur biogeochemistry in regulating Earth's surface oxidation …

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 …

Abstract The Permian-Triassic mass extinction was the most severe biotic crisis in the past
500 million years. Many hypotheses have been proposed to explain the crisis, but few …
