A team of researchers from 8 countries is trying to understand the links between the largest continental volcanic eruption (the Siberian flood basalts) and the largest extinction in Earth history (the end-Permian). Funded by NSF, we are in the middle of a five-year interdisciplinary project looking at paleontology, geochronology, crustal rocks, volcanic rocks, paleomagnetism, and gravity to try to understand the connections between these events. This video shows one aspect of our project through our 2010 field trip; more information can be found on siberia.mit.edu.
