The density, compressibility and seismic velocity of hydrous melts

Abstract

We construct the model that describes the density of the silicate melt as a function of T, P, H₂O content and the melt composition. A set of volumetric parameters for the H₂O component in the melt are newly calibrated using the results of previous high pressure experiments. The parameter set will be used for the calculations of density, thermodynamic properties and seismic velocity of various hydrous melts.
