Formula:
Pd8As2S
May be a S-substituted stillwaterite. Not known in the Pd-As-S system. Chemically close to 'UM1984-12-AsS:Pd' and 'Unnamed (Pd Arsenide Sulfide)'.
In uraninite-bearing shale and adjacent dolomite of the Lubin and Polkowice mines, within Zechstein Cu deposits of the Fore-Sudetic Monocline, Poland.
As irregular grains intergrown with native gold (the analyzed grain was 8 x 16 microns in size).
Compare Pd-As species from the same locality, e.g., 'UM1984-05-As:Pd' (the most common one), 'Unnamed (Pd Arsenide)', 'Unnamed (Pd Arsenide II)', 'UM1975-06-As:Pd', 'UM1984-01-As:AgAuCuNiPdS', 'UM1984-06-As:Pd', 'UM1984-07-As:Pd'.
