Mössbauer spectra of Fe 2+ Fe 3+ and Fe 2+ Al hydroxycarbonates taken in the paramagnetic state were fitted using two Fe 2+ and Fe 3+ doublets each. These spectra can be interpreted in terms of an ordered cation arrangement in the pyroaurite-type structure. The inner Fe 2+ doublet seems to be the outcome of excess Fe 3+ in the samples studied. The outer Fe 2+ doublet (quadrupole splitting ∼2·8 mm s −1 , FWHM = 0·26 mm s −1 ) is relatively well-defined and can, together with the fact that this doublet disappears on oxidation, possibly serve to identify these compounds in natural systems.
