Name:Named after the Norwegian mineralogist Per Bøe, Tromsø University.


Member of a polysomatic series having epidote and törnebohmite as end-members.
Form a continuous solid-solution series with alnaperbøeite-(Ce). Members of the perbøeite-(Ce)–alnaperbøeite-(Ce) solid solution are topologically identical to the minerals gatelite-(Ce) and västmanlandite-(Ce). Perbøeite-(Ce) derives from gatelite-(Ce) by the homovalent substitution [M3Fe2+ → M3Mg].

Both perbøeite-(Ce) and alnaperbøeite-(Ce) may be present in a singel crystal, and the two cannot be distinguished visually.
