Scientists have identified the Northern Appalachian Anomaly, a massive molten rock formation beneath New England, which originated from the Labrador Sea 80 million years ago and continues to drift slowly, influencing Earth's geological structure and supporting theories of mantle wave activity that shape continental features over millions of years.
A seismic study uncovered a massive, 12.4-mile-thick rock layer beneath Bermuda, challenging existing geological models and suggesting ancient volcanic activity may have contributed to the island's uplift, which defies typical mantle hotspot patterns. This discovery could reshape understanding of island formation and Earth's crustal processes.
A study reveals a massive, hot mantle anomaly beneath New England, originating from the late Cretaceous Labrador Sea rifting, and migrating west-southwest over millions of years due to mantle dynamics, challenging traditional views of North American tectonic stability.
