This page is currently not sponsored. Click here to sponsor this page.
Formula:
Cu3-xAs
Appears to be a Cu deficient domeykite.
Lustre:
Metallic
Dimorph of:
A Cu-deficient "domeykite" with a few extra powder diffraction lines. Possibly a new phase here as with Cu-deficient chalcocites and covellites. Possibly visually indistinguishable from domeykite.
