scientist from the University of Maryland have make a groundbreaking discovery refer an ancient seafloor that sink deep into the Earth during the being of dinosaur. This previously unknown seafloor spot, found in the East Pacific Rise, supply penetration into the planet's inner works and how its surface has evolve over million of old_age. The team's findings were recently print in the diary Science Advances. light-emitting_diode by geology postdoctoral research_worker Jingchuan Wang, the scientist use advanced seismic imagination technique to dig deep into the Earth's mantle, disclosure an unusually midst area in the mantle passage zone.
The mantle passage zone, locate between 410 and 660 kilometer below the Earth's surface, offprint the upper_berth and lower_berth mantle and can expand or contract establish on temperature. Wang's team belief that this newly detect seafloor could also explain the Pacific Large Low Shear Velocity Province's anomalous structure. The thicken area is compare to a fossilize fingerprint of ancient seafloor that submerge into the Earth around 250 million old_age ago, offer a alone glance into Earth's past.
subduction happen when one tectonic home_plate descend beneath another, recycling surface material back into the Earth's mantle. While geologist traditionally analyze subduction exploitation surface rock sample, Wang and his team use seismic wave to analyze the ocean floor, make detail function of the mantle's internal structure. The scientist detect that material was travel more slowly through the Earth's inside than previously assume, bespeak the presence of cold material in the mantle passage zone. This propose that some Oceanic slab may get lodge while sinking through the mantle, neutering our understanding of Earth's deep structure and their impact on surface geology.
The team plan to expand their research beyond the Pacific Ocean, aim to map extra ancient subduction and upwelling zone to enhance model of tectonic home_plate motion throughout Earth's history. Wang belief that numerous ancient structure stay undiscovered in the Earth's deep inside, each retention the potential to unveil new penetration about our planet's complex past and possibly shed light on other planetal body. The Holocene publication of their findings in Science Advances Marks just the beginning of a journey towards a deep understanding of Earth's geological history and its deduction for the future.
