Table 5 of Hawthorne et al. (Reference Hawthorne, Uvarova and Sokolova2019) lists five minerals: arapovite, ekanite, iraqite-(La), steacyite and turkestanite, as belonging to the ekanite group, with a sheet structure consisting of folded [4.82] sheets of tetrahedra of the form [Si4O10]. Ekanite (Szymański et al., Reference Szymański, Owens, Roberts, Ansell and Chao1982) is a sheet structure consisting of folded [4.82] sheets of tetrahedra and is classified correctly. However, in the other minerals mentioned above, the silicate unit consists of a four-membered double-ring of the form [Si8O20] as correctly illustrated by Uvarova et al. (Reference Uvarova, Sokolova, Hawthorne, Agakhanov and Pautov2004). Arapovite (Uvarova et al., Reference Uvarova, Sokolova, Hawthorne, Agakhanov and Pautov2004), iraqite-(La) (Livingstone et al., Reference Livingstone, Atkin and Hutchison1976), steacyite (Perrault and Szymański, Reference Perrault and J.T.1982) and turkestanite (Kabalov et al., Reference Kabalov, Sokolova, Pautov and Schneider1998) are not sheet silicates and do not belong in this paper. We apologize for this miserable error.
