The chevkinite-group minerals from the Woshui syenites are unique in that they display positive chondrite-normalized Eu-anomalies (i.e. Eu/Eu* = 2.3 to 23) which may be related to the conditions that produced the parental magma. The magmatic conditions of Woshui pluton were likely to be low pressure (i.e. ≤ 1 kbar), moderate temperature (i.e. 700–800°C) and relatively oxidizing (fO2 ≥ FMQ > 0). In comparison to chevkinite-group minerals reported from peralkaline rocks, those from metaluminous rocks tend to have higher SiO2, Al2O3, CaO and ZrO and lower FeO*, Nb2O5 and Ce2O3. The compositional differences are attributed to parental magma composition and possible magmatic origin (i.e. partial melting vs. crystal fractionation).
