The solubility and oxidation state of tungsten in silicate melts: Implications for the comparative chemistry of W and Mo in planetary differentiation processes

O'Neill, Hugh; Berry, Andrew; Eggins, Stephen


The solubility of W in 18 melt compositions in the system CaO-MgO-Al2O3-SiO2 in equilibrium with W metal was determined as a function of oxygen fugacity (fO2) at 1400 °C and atmospheric pressure, using CO-CO2 and H2-CO2 gas mixtures to control fO2. Samp
