1926 P. Geijer in Geol. Förening. Stockholm Förhandl. 48 84 Norbergite. Only in massive aggregates, crystal system unknown... The proposed name is derived from the name of the district, since that of the mine is unsuitable for an international nomenclature.

1968 Mineral. Mag. 36 966 The polyhedral distortions in norbergite are smaller than in forsterite in accord with the decreased number of shared edges.

1992 W. A. Deer et al. Introd. Rock-forming Minerals (ed. 2) 19 The refractive indices and densities of the humite minerals increase progressively from norbergite to clinohumite.
