Rock-Forming Minerals: Orthosilicates, Volume 1A:
Fayalite is not stable in the system FeO-Fe2O3-SiO2-H2O in the presence of an
aqueous phase below 250°C and decomposes to magnetite and greenalite,
Fe3Si2O5(OH)4 (a ferrous iron analogue of serpentine), in this environment.
Fayalite ...

The tap slags are rich in fayalite, almost the sole constituent of the earliest iron
slags known from antiquity (Cleere 1976: 128), but also in kirschteinite and
various Fe-Ca silicates and Al silicates which do not occur in the bloom slag.
Moreover ...
