In the final print and online versions of the title article, an incorrect version of Table 3 (p. 668) containing sugilite microprobe analyses was inadvertently included. The correct version of Table 3 appears below and the authors apologise for any inconvenience.

Table 3

Chemical composition and cation proportions of selected analyses of sugilite Na₂K(Fe³⁺,Mn³⁺,Al)₂Li₃Si₁₂O₃₀ from Bruce mine.
