UM2000-28-O:BiPdSb
Invalid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pd3(Sb,Bi)2O4 (?)
Smith & Nickel (2007) report it to actually be a solid solution between Pd(Sb,Bi)O^2 and Pd^2(Sb,Bi)O
Co-described with UM2000-40-O:PdSb and UM2000-27-O:BiPd.
As rims, 10–30 µm wide, on Bi-bearing sudburyite . Associates include chalcopyrite. Presumably of a non-supergene origin. Nevertheless, suggested to form in expense of the sudburyite.
Electron microprobe data, wt.% (1 of 3 analyses):
Fe 0.62
Cu 0.50
Bi 20.69
Pd 43.63
Sb 25.23
S 0.11
O 8.82
total 99.60
