Behavior and properties of water in silicate melts under deep mantle conditions.

ABSTRACT: Water (H₂O) as one of the most abundant fluids present in Earth plays crucial role in the generation and transport of magmas in the interior. Though hydrous silicate melts have been studied extensively, the experimental data are confined to relatively low pressures and the computational results are still rare. Moreover, these studies imply large differences in the way water influences the physical properties of silicate magmas, such as density and electrical conductivity. Here, we investigate the equation of state, speciation, and transport properties of water dissolved in Mg_1-xFe_xSiO₃ and Mg_2(1-x)Fe_2xSiO₄ melts (for x = 0 and 0.25) as well as in its bulk (pure) fluid state over the entire mantle pressure regime a
