UM1979-15-S:AgSbTe

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ag8Sb(S,Te)6
Reported, as "Mineral C", from Ivigtut cryolite deposit, Greenland; found in galena or as intergrowths with hessite, tellurian canfieldite or freibergite. The associated "Mineral D" with proposed (Ag,Cu)PbBi2S5 formula likely corresponds to 'argentocosalite' or 'argentocosalite'.

Might be an impure benleonardite or polybasite. On the other hand, it might be the Sb analogue of canfieldite and argyrodite.
