Effect of H2O on the density of silicate melts at high pressures: Static experiments and the application of a modified hard-sphere model of equation of state

Density of ultramafic silicate melts was determined using the sink/float technique at high pressures. Seven melt compositions were studied, among which three were dry compositions with different Mg#’s (molar MgO/(MgO+FeO)×100) and the other four were hydrous compositions synthesized by adding 2–7wt....
