Abstract

Compressional ( V P ) and shear ( V S ) 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 K 0  = 123(1) GPa, K 0 ′ = 5.1(2), G 0  = 75(1) GPa, and G 0 ′= 1.3(1) for the bulk and shear moduli and their pressure derivatives. Comparison with Voigt‐Reuss‐Hill (VRH) calculations based on literature elasticity data for its constituent minerals indicates that the experimentally measured P and S wave velocities, densities, bulk sound velocities, and V P / V S ratios fall close to the lower limit of VRH averages associated with the uncertainties of the mineral elasticity data. A comparison with previous modeling of mantle compositions implies that the velocities for an aggregate with the pyrolitic composition of KLB‐1 are in close agreement with seismic data at the depths of the Earth's upper mantle.
