Experimental study of the influence of water on elastic wave velocities in dunite and serpentinite (on the nature of the low-velocity zone in the upper mantle of the Earth)

Longitudinal wave velocities ( V P ) in rocks were measured experimentally in dunite (olivinite) and serpentinite at a water pressure of 300 MPa and temperatures of 20–850°C. It is shown that the strong decrease in V P in dunite (by ~3 km/s) observed within the range of 400–800°C results from penetr...
