Introduction. Mercury (Hg) emissions associated with the emplacement of Large Igneous Provinces (LIPs) were first recognized by Sanei, Grasby & Beauchamp (Reference Sanei, Grasby and Beauchamp 2012), who showed a large Hg spike associated with the Siberian Traps eruptions.This event was coincident with the Latest Permian Extinction (LPE), the largest extinction in Earth's history that had a ...Harmful microbial blooms across the post-extinction lowlands.

The Permian-Triassic Extinction event marked the end of the Phanerozoic Era, which had spanned 289-million years. However, despite the profound transformation of our world, and despite suffering unimaginably heavy losses, some important groups did manage to survive, including the dicynodonts, which survived well into the Late Triassic. ...

Although the best-known cause of a mass extinction is the asteroid impact that killed off the non-avian dinosaurs, in fact, volcanic activity seems to have wreaked much more havoc on Earth's biota. Volcanic activity is implicated in at least four mass extinctions, while an asteroid is a suspect in just one. And even in that
