▪ Mills, S.J., Whitfield, P.S., Kampf, A.R., Wilson, S.A., Dipple, G.M., Raudsepp, M., Favreau, G. (2012): Contribution to the crystallography of hydrotalcites: the crystal structures of woodallite and takovite. Journal of Geosciences, 57, 273-279.


The crystal structures of the 3R polytypes of takovite and woodallite are presented. The structure of takovite was solved on a single crystal from the Agoudal mine, Bou Azzer district, Tazenakht, Morocco to R1 = 1.87 % for 94 unique reflections 4σF> in R-3m, with unit cell parameters a = 3.0290(2) and c = 22.5995(15) Å. The crystal structure of woodallite R-3m, with unit cell parameters a = 3.10124(8) and c = 23.6817(16) Å> was refined utilising the Rietveld method on a sample from the MKD5 orebody at the Mount Keith Nickel Mine, Western Australia.
