Edit Add Synonym Edit CIF structures Clear Cache

Formula:

(Ag,Cu)Bi₃(Se,S)₅

Unique combination of elements. Co-described with 'UM1989-27-Se:AgAsFeS' and 'UM1989-29-Se:Te'.
Probably a Cu-bearing variety of Unnamed (Se-analogue of Pavonite).

Occurs as grains, 60-80 microns in size, occurring close to gold and a phase corresponding to (Bi,As,Te,Se)₂O₃, all within quartz.

Likely formed due to fSe activity increase at ca. 150-200^oC; relatively late-stage species.
