Most of the metasediments that make up the bulk of our mountains are remnants of the seafloor that were exposed to subduction at one stage. So the head line: "Ancient fragment of the Pacific Ocean found buried 400 miles below China" is a bit too sensationeel The only difference with the slab now identified by seismic means is that it has not yet been deformed and uplifted into an orogenic belt.
