UM2004-31-S:AgAuCuTe

Valid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ag,Au,Cu)9Te2S3
or maybe (Ag,Cu)25Au2Te6S9
Crystal System:
Isometric
Co-described with chemically similar UM2004-34-S:AgCuTe. Compare, e.g., benleonardite which is another example of a similar composition.

Might represent a unique combination of elements.

Both unnamed species are found as grains, up to 13 μm in length.

Intergrown with kostovite and petzite.

Both species replace hessite, goldfieldite, petzite, and tetrahedrite.
