Seminar Room MCZ, 429

Speaker: Mark Baum

Mark will lead a discussion on Initial pulse of Siberian Traps sills as the trigger of the end-Permian mass extinction.

In the discussion, Mark will lead us through the following key points:

  • Global climate change induced by large igneous province (LIP) magmatism has been linked to three of the five mass extinctions in the past ~540 million years.
  • LIPs are emplaced over millions of years but mass extinctions happen over hundreds of thousands of years, a significant disparity.
  • A particularly deadly subinterval of LIP magmatism, which caused heating of volatile-rich sediments and release of greenhouse gasses, is proposed as the cause of the most severe mass extinction on record, the end-Permian extinction.
