Mössbauer spectra and Fe coordination polyhedra, with conventions as in Figure 1. Lithiophilite (Losey et al. 2004) DD135 contains a small amount of Fe3+ but its spectrum is dominated by Fe2+; both are in the M2 site. The spectrum of ludlamite (Abrahams and Bernstein 1966) DD219 has a small siderite impurity as well as doublets from Fe2+ and Fe3+ assigned to the M2 site. Lulzacite (Léone et al. 2000) DD197, although dominated by siderite, has two Fe2+ doublets assigned to M1 and M4. Lüneburgite (Sen Gupta et al. 1991) DD218 has a distinct Fe3+ doublet with δ more typical of tetrahedral Fe3+, but are more reasonably attributed to M1 and M2. Maricite (Le Page and Donnay 1977) MDD14 contains both Fe2+ and Fe3+ in the Fe site. In messelite (Fleck and Kolitsch 2003) DD228, Fe is only in the Fe site. In metavivianite (Chukanov et al. 2012) DD319, Fe2+ is distributed between two octahedral sites and Fe3+ occupies only one site, though it is unclear if it is Fe1 or Fe2. In landesite (Moore et al. 1980) ML-P26, three doublets represent Fe3+ in Fe1, Fe2+ in M2, and Fe2+ in M1, respectively. (Color online.)
