Elastic wave velocities of peridotite KLB-1 at mantle pressures and implications for mantle velocity modeling

Compressional (VP) and shear (VS) wave velocities of a synthetic KLB‐1 peridotite were measured for the first time up to 10 GPa using ultrasonic interferometry. Analysis of the P and S wave velocities yielded K0 = 123(1) GPa, K0′ = 5.1(2), G0 = 75(1) GPa, and G0′= 1.3(1) for the bulk and shear modul...
