- University of Maryland geologists discovered an ancient seafloor beneath the Pacific Ocean, challenging theories about Earth's mantle dynamics. - The Phoenix Plate, a tectonic plate subducted during the Mesozoic era, may have influenced Earth's mantle structure for over 100 million years. - Using seismic imaging technology, the team mapped out a mysterious portion of Earth's mantle transition zone, found to be unusually thick and cold. - The ancient seafloor may have split the Large Low Shear Velocity Province (LLSVP), a massive region of Earth's lower mantle. - The discovery could lead to revisions in models of plate tectonics and provide a better understanding of Earth's surface evolution.

University of Maryland geologists discovered an ancient seafloor beneath the Pacific Ocean, challenging theories about Earth's mantle dynamics.
The Phoenix Plate, a tectonic plate subducted during the Mesozoic era, may have influenced Earth's mantle structure for over 100 million years.
Using seismic imaging technology, the team mapped out a mysterious portion of Earth's mantle transition zone, found to be unusually thick and cold.
The ancient seafloor may have split the Large Low Shear Velocity Province (LLSVP), a massive region of Earth's lower mantle.
The discovery could lead to revisions in models of plate tectonics and provide a better understanding of Earth's surface evolution.
