摘要/描述

Density measurements of eight silicate liquids containing substantial amounts of Fe203 have been made over a range of 250℃ These have been combined with published density measurements on multicomponent silicate liquids to yield (by multiple regression) partial molar volumes of SiO2, TiO2, A1203, Fe2Oa, FeO, MgO, CaO, Na20, and K20. The data on Fe203-liquids are neither precise nor abundant enough to show a compositional dependence of V-liqFe2O3. In a liquid of constant composition and temperature, the pressure dependence of the oxygen fugacity is given by.
