(1983) studied synthetic AsSb[O.sub.3], which they demonstrated to be isostructural with claudetite (A[s.sub.2][O.sub.3]) (Pertlik, 1978).
(1958) first reported claudetite from Tsumeb as gypsum-like platelets.
The ordering of Sb into a single As position of the claudetite structure is apparently unique to the claudetite and stibioclaudetite structure (Origlieri et al., 2009).
Monoclinic [As.sub.2][O.sub.3] (claudetite) forms above 250[degrees] C, while cubic [As.sub.2][O.sub.3] (arsenolite) has a melting point near 275[degrees] C (Schulman and Schumb, 1943).
Stibioclaudetite crystals mimic the morphology of claudetite from Imperial Valley, California as illustrated by Palache (1934), shown in Figure 3.
