Minerals of the axinite group in Miskolc-Lillafrired are represented by only axinite- (Fe) which created here two generations. Younger one is Mg-enriched in contrast to older, Fe-enriched generation. Zonality is sometimes irregular, but some crystals of axinite exhibit systematic zonality, where central parts of crystals are enriched in Fe (Mn) and peripheral zones are enriched in Mg. Trend of zonality of Mn <-> Mg + Fe2+ is identical to the general trend in minerals of axinite group from the most of occurrences in the world (Andreozzi et al., 2000). Substitution MgFe , is rarer in axinites and it is present in Mg-rich axinite-(Fe) in Limbach (Fig. 6).
