Unexpected Oceanic Lithosphere-Asthenosphere P-wave Velocities

by K. Rychert 13 August 202010 March 2022

A peak in seismic P-wave – S-wave velocity ratios at the lithosphere-asthenosphere boundary beneath old Pacific lithosphere requires an additional property besides temperature as an explanation.
