Formula:
Ag5Bi13Se22
Crystal System:
Monoclinic
The Se analogue of dantopaite.
Most probably identical with Unnamed (Se-analogue of Dantopaite) which was identified as the Se-analogue on the basis of quantitative EPMA data (which gave the empirical formula Ag4.53Cu0.53Bi12.68Pb0.59Se19.29S2.71, based on 22 (Se+S) atoms). It occurs as tiny (up to 8 micron), indistinct crystals in association with coffinite, uraninite and guanajuatite at the famous Clara mine, Black Forest (Kolitsch et al., 2019).
