矽卡岩中的铁硅灰石的大致组成为Ca 5 FeSi 6-O 18。来自Kagata矿的铁硅灰石和普通硅灰石分别与hedenbertite和亚铁盐组成的单斜辉石有关。这一现象可以解释为Ca_5FeSi_6-O_（18）组成的铁-硅灰石与普通硅灰石之间存在着可熔性差距。因此，Ca 5 FeSi 6-O 18组成的铁-硅灰石似乎是CaSiO 3-CaFeSi 2 O 6结合体中的稳定相，其温度与矽卡岩形成的温度一样低，可能为300° C至600°C。
Iron-wollastonites from skarns have an approximate composition of Ca5FeSi6-O18. Iron-wollastonites and ordinary wollastonites from the Kagata mine are associated with clinopyroxenes of hedenbergite and ferrosalite compositions, respectively. This fact could be interpreted as that a miscibility gap exists between iron-wollastonite of Ca5FeSi6-O18 composition and ordinary wollastonite. Thus iron-wollastonite of Ca5FeSi6-O18 composition appears to be a stable phase in the CaSiO3-CaFeSi2O6 join at temperatures as low as those of the skarn formation, probably 300°∼600°C.
