... in which iron octahedra are linked by sulfate tetrahedra in the monoclinic space group P 2 1 / m with lattice parameters a = 10.711(1), b = 11.085(1), and c = 5.5747(5) Å, β = 98.853(3)°. We compare these results with the type specimen of lausenite from Jerome, Arizona, which has monoclinic lattice...

Top view of the crystal structures of kornelite and lausenite, shown as polyhedral models (left) and topological schemes (right). In the topological schemes, only the cations are shown, Fe3+ as grey circles and S6+ as white circles. Dashed lines in the scheme of lausenite show the polyhedral linkages that need to be broken in order to allow the transformation from lausenite to kornelite.

Crystal structures of the lausenite (Majzlan et al., 2005), kornelite (Robinson & Fang, 1973), dehydrated kaňkite (this work), and a hypothetical model of the possible kaňkite structure. The transformation between kornelite and lausenite is reversible (Kong et al., 2011), as shown by the double arrow. The transformation between kaňkite and dehydrated kaňkite cannot be probably reversed, as shown by the single arrow. Small grey arrows indicate the points where the As-O-Fe or S-O-Fe bridges must be broken in the dehydrated forms to obtain the sheet of the hydrated form.

Powder X-ray diffraction pattern of lausenite with the calculated positions of the diffraction peaks. This pattern was collected in a flat-plate geometry, and the differences in relative intensities of the peaks in this pattern and the synchrotron pattern (cf. Fig. 2) is due to preferred orientation that could not be completely avoided in this geometry.

The phase diagram for the system Fe2O3 – SO3 – H2O at 110°C as determined by Posnjak & Merwin (1922). The location of (H3O)Fe(SO4)2 and rhomboclase are indicated by filled diamonds. Fluids in equilibrium with solids are indicated by circles connected by tie-lines. Lausenite, Fe2(SO4)3·5H2O, and Fe2(SO4)3·6H2O are both plotted. Majzlan et al.(2005) described the atomic structure of Fe2(SO4)3·5H2O.

Mössbauer spectra and Fe coordination polyhedra in sulfates with very small Δ values less than ~0.35 mm/s. Data points are plotted are ±standard deviations but are cropped at the baseline, which is defined to be 100% absorption. Polyhedra were created using CrystalMaker software and data from the American Mineralogist Crystal Structure Database: quenstedtite (Thomas et al. 1974), coquimbite (Fang and Robinson 1970), kornelite (Robinson and Fang 1973), lausenite (Majzlan et al. 2005), ferrinatrite (Scordari 1977), voltaite (Mereiter 1972), and rhomboclase (Mereiter 1974). O atoms are shown in red, OH in gray, Al in blue, and Fe in orange. Note that XRD suggests that the R6214 ferrinatrite contains minor amounts of coquimbite that cannot be distinguished because the spectra are so similar. (Color online.)
