Unnamed (Se-analogue of Dantopaite)

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ag5Bi13(Se,S)22
Empirical formula:
Ag4.53Cu0.53Bi12.68Pb0.59Se19.29S2.71 (based on 22 (Se+S) atoms).
Chemically, the Se analogue of dantopaite. The isotypy is not proven yet.
Selenodantopaite was later described from a Czech locality.

Tiny (up to 8 micron), indistinct crystals in association with coffinite, uraninite and guanajuatite.
