Seismic Analysis Reveals Ancient Mantle Flow Beneath Pacific Plate
Recent seismic data gathered by ocean-bottom instruments have uncovered fossilized traces of mantle flow beneath the oldest preserved section of the Pacific Ocean crust. These intricate patterns offer new insights into the historical movements and deformations of tectonic plates. Researchers found that the uppermost mantle records complex changes in plate motion over millions of years. This includes structural deformations around sunken lithospheric remnants and dynamic upwelling from thermal hotspots.
