1910 W. T. Schaller in Amer. Jrnl. Sci. 180 358 I propose to call this particular monoclinic soda feldspar barbierite, in honour of Prof. Ph. Barbier, of the University of Lyons, France.
1913 Min. Mag. XVI. 354 Barbierite..Monoclinic soda-feldspar (NaAlSi3O8) isomorphous with orthoclase and dimorphous with albite.
1957 Encycl. Brit. IX. 152/1 Such a [monoclinic] modification was earlier proposed..and given the name barbierite, but its reality as a mineral has been disputed.
