Abstract
Rayleigh wave phase velocities on paths crossing the Pacific Ocean show variations which are well correlated with some "average" lithospheric age of the region traversed. The seismic velocities in the upper mantle are highest in the oldest parts of the Pacific and lowest in the youngest parts.Keywords
