A large region of unusually hot rock deep beneath the Appalachian Mountains in the United States could be linked to Greenland and North America splitting apart 80 million years ago, according to new research led by the University of Southampton.



Summary

A vast zone of hot rock deep beneath the Appalachian Mountains, discovered through seismic imaging, might be a remnant of the tectonic activity that separated Greenland and North America. Researchers at the University of Southampton propose this hotspot, originating from deep within the Earth, could be the missing piece explaining the geological history of the region. While currently stable, the anomaly sheds light on ancient rifting events and offers insights into how continents break apart. This research connects present-day geological features to events that occurred millions of years ago during the breakup of the supercontinent.
