[edit] Wikipedia's way of chemical formulas.

Why does wikipedia have to find the worst way of writing a chemical formula? For example Grunerite Fe7Si8O22(OH)2 - it's composed of Si2O11(-6) so it's rather like Fe7(Si2O11*OH)2 (as well as Fe7(Si2O11/OH)2 or Fe7(Si2O11)2(OH)2, as just to note you can't find anything for (Si8O22) only Si4O11(-6).

The empirical formula used in the article matches that in my copy of Deer, Howie & Zussman "The rock forming minerals", and those in both the Webmineral and Mindat webpages - they all use (Si₈O₂₂). Mikenorton (talk) 12:14, 1 January 2011 (UTC)
