1941 V. I. Gerasimovsky in Compte Rendu de l'Acad. des Sci. de l'URSS 32 496 A more detailed study of the mineral has shown that it cannot be identified with any of the minerals already known, and therefore it was given a new name—nordite (because of its northern origin).
1970 Amer. Mineralogist 55 1167 The structure of nordite is closely related to the structures of melilite and datolite–gadolinite, and can be considered as an unusual combination of both.
1999 Crystallogr. Rep. 44 565 The silicate ribbons in nordite are topologically comparable with those in vlasovite and haiweeite.
