Seismic analysis reveals ancient traces of mantle flow beneath the Pacific's oldest plate

Seismic data captured by ocean-bottom instruments have revealed "fossilized" traces of mantle flow beneath the Pacific Ocean's oldest preserved piece of crust. The patterns of ancient flow traced in the uppermost mantle are complicated, tracking changes in tectonic plate motion o This story matters for Science & Discovery readers tracking insect.
