MEASUREMENT OF P AND S SOUND VELOCITIES UNDER PRESSURE ON LABORATORY MODELS OF THE EARTH'S MANTLE

Abstract

The results of velocity measurements performed on specimens of polycrystalline forsterite with 6% porosity, a single crystal spinel, and on obsidian are reported. The velocities of compressional and shear waves were determined at both ambient (25C and 1 bar) conditions and as a function of pressure on all three specimens. Velocity as a function of temperature was measured to 150C at 1 atm on the obsidian specimen.
