About 252 million years ago, the largest mass extinction and the largest volcanic eruptions in Earth history occurred
Is it coincidence or causality? We have a hypothesis, and it ties closely with current climate changes.

The possible relationship between the Siberian large igneous province and the end-Permian extinction, the most significant mass extinction in Earth history, has been discussed for more than a decade. Our mission is to explore this further by investigating:
The rates of eruption of the tuffs and lavas, and the dates of the intrusive rocks
The possible volatile emissions of the tuffs and the country rocks the lavas erupted through
An initial integrated seismic, gravity, magnetic, and geodynamic investigation of the Siberian lithosphere
Climate modeling and the effects of carbon and sulfur injections into the atmosphere
