Link established between meteorite impact and massive volcanism 30 mln yrs ago In a new research, scientists have discovered the second example of a meteorite impact that occurred at the same time as massive volcanic activity 30 million years ago in Belarus. The first time such a coincidence was observed, at the Cretaceous-Tertiary boundary, was the catastrophic event thought to be responsible for the extinction of the dinosaurs, 65 million years ago. This new event, uncovered after the 17 km diameter Logoisk impact structure in Belarus was precisely dated, is thought to have taken place around 30 million years ago.
