Abstract Hejtmanite forms prismatic or platy crystals up to 1 mm long enclosed in manganoan arfvedsonite at Mbolwe Hill, Mkushi River area, Central Province, Zambia. The composition is (microprobe analysis): SiO2 23.52, TiO2 13.27, Nb2O5 1.4, Al2O3 0.37, FeO(tot) 11.29, MnO 14.12, MgO 0.13, BaO 30.2, Na2O 0.06, K2O 0.30, F 3.3, Cl Fe2+ members of its solid solution series towards bafertisite.
