The partition experiments of NaCl and KCl between silicate melts and aqueous chloride solutions were carried at a temperature of 810°C in the pressure range from 0.6 to 6.0 kb. The chloride concentration in the melt ( C Cl m ) was constant in certain ranges of chloride concentration in the aqueous phase ( C Cl aq ) at 0.6 and 1.2 kb, which reveals the presence of vapor-liquid immiscibility of the aqueous solution. The variation diagram of C Cl m and C Cl aq can be applied to the study of aqueous phases as a new method. The partition ratio of chloride ( D Cl m / aq = C Cl m / C Cl aq ) exhibits a strong negative pressure dependence, which is attributed to the large negative partial molar volume of chlorides in the aqueous phase. The distribution coefficient of Na and K ( D Na / K M / Aq = ( C Na m / C K m / C Na aq / C K aq )) is about 0.75 and has little pressure dependence at pressures higher than 2.2 kb. The distribution coefficient, however, has a positive pressure dependence at pressures lower than 1.2 kb.
