TSU will reveal the role of volcanoes in the extinction of species

Scientists at the Laboratory of Geochronology and Geodynamics will be investigating the correlation between magmatic processes and mass death of biological species at the end of the Ordovician period. Using radioisotope dating, researchers will see what happened almost 400 million years ago and estimate the ecological conditions of that time. This will help to understand whether the largest eruption of ancient volcanoes could have led to a biological catastrophe, as a result of which 85% of living organisms disappeared from the Earth’s surface.
- Modern studies indicate that one of the most important factors in the sudden change in the environment was large intraplate magmatic events, called large igneous provinces (LIPs), - said Richard Ernst, head of the Laboratory of Geochronology and Geodynamics, a scientist at TSU and Carleton University. - Large-scale emissions of magma and greenhouse gases of at least 100,000, and more often up to 1 million, cubic kilometers led to dramatic climate changes - acid rains, sea level change, global warming, and glacial periods.
