抄録

Experiments on ion exchange of Ca2+, Fe2+ and Mn2+ between grossularalmandine-spessartine garnet solid solution and 2N aqueous chloride solution were conducted at 600°C and 1 kb under relatively reducing conditions in order to determine the stability relation and mixing property of the garnet solid solution. The experimental results revealed that calcium ion is slightly preferentially partitioned into aqueous chloride solution compared with ferrous and manganese ions. Grossular, almandine and spessartine form an almost continuous solid solution except for the semicircular region along the grossular-almandine join, where mineral assemblages of fayalite+anorthite and hedenbergite+anorthite+wustite appear instead of the garnet solid solution. Mixing properties of the garnet solid solution were evaluated from the experimental results by considering the formation of FeCl3−aq and MnCl3−aq in the aqueous phase. Almandine-spessartine solid solution shows slightly negative deviation from ideality. On the other hand, grossular-spessartine solid solution shows slightly positive deviation. Mixing property of grossular-almandine solid solution was not well determined due to the large unstable region.
