Abstract

In order to estimate water content in the low velocity anomalies of the crusts, it is important to understand the influence of geofluids on the elasticity of crustal materials. Here we examined the effect of fluid on compressional wave velocities (Vp) and shear wave velocities (Vs) for gabbronorite at pressures to 1.0 GPa and temperatures to 1073 K corresponding to lower crusts of island arcs.
