摘要：
Rayleigh waves recorded with an ocean-bottom seismograph array in the central Pacific Ocean constrain the seismic anisotropy within the oceanic lithosphere–asthenosphere system: seafloor-spreading-induced lithospheric fabric generates the strongest anisotropy, while density- and/or pressure-driven flow produces a secondary peak in anisotropy at the base of the asthenosphere.
