We conducted this research to gain understanding of the mineral rouxelite, which contains elements like antimony, copper, mercury, and lead. Using advanced X-ray techniques, we re-examined its crystal structure and discovered new details, such as unit-cell parameters, symmetry, and substitutions. These findings provide accurate information about how the mineral forms and behaves. This work not only updates scientific knowledge of rouxelite but also offers insights into its chemical complexity.

Chromites found within the fusion crust of ordinary-chondrite meteorites display significant differences with respect to chromites found in the interior of the same meteorites. Chromites within the fusion crust, when compared to those in the interior of the meteorite, display a significantly higher Mg / (Mg + Fe) ratio; moreover, ca. 15 % of the chromites formed within the crust display small but detectable amounts of Ni.
