Title: Sound velocity on SiO/sub 2/ hugoniots

Abstract

Measurements of release velocities in various samples of SiO/sub 2/ shocked into the pressure range of 47-67 GPa are reported. The first direct observation of a longitudinal release wave in SiO/sub 2/ at these high pressures is reported. The resulting sound speed data along the Hugoniot, combined with the Hugoniot, permit a calculation of the Gruneisen parameter along the Hugoniot. Because the pressure-temperature region of the experiments approximates middle mantle conditions, the longitudinal and bulk velocity measurements for SiO/sub 2/ have immediate implications for composition constraints to fit seismic profiles of sound velocities.
