Name:
Name introduced by Bertossa (1969) for a barian arrojadite described by von Knorring (1969) from the Buranga pegmatite, Rwanda. It occurred here as a yellowish green mineral intergrown with pyrite and chalcopyrite. It was later shown, according to the newly revised nomenclature of the arrojadite group, by Chopin et al. (2006) to be identical with Arrojadite-(BaFe).
