Experts are baffled by structures under Pacific that shouldn't exist

The article from MSN discusses the discovery of mysterious structures beneath the Pacific Ocean, specifically under the Bering Sea, which have left scientists puzzled. These structures, identified through seismic imaging, appear to be remnants of an ancient ocean floor that was subducted millions of years ago. What baffles experts is the unexpected composition and location of these structures, which do not align with current geological models. Typically, subducted material would be expected to melt and mix with the mantle, but these structures seem to have retained their original form, suggesting they might be made of a material that is more resistant to the extreme conditions of the Earth's mantle. This finding challenges existing theories about plate tectonics and the behavior of subducted oceanic crust, prompting further research into the Earth's deep interior processes.
