... of the type M (1) > M (3) ≈ M (2) for a B (Mg-Fe-Mn) amphibole with 0.75 Zn a.p.f.u. (at that time called “zincian tirodite”, now “clino-suenoite” after Hawthorne et al. , 2012 ). This assumption was based on unconstrained refinement and should be re-examined in the light of present knowledge...
