Ni3As3(S,Se)4
As anhedral grains, below 10 microns in diameter). Associated with tiemannite, clausthalite, antimonselite, lautite, famatinite, gold, quartz, baryte.
Electron microprobe data (wt.%): Ni 24.1, 29.4; As 27.6, 33.9; Hg 7.6, 5.4; S 13.9, 15.6; Se 14.2, 12.7; Cu 0.3, 0.5; Fe 0.2, 0.2; Ag 0.1, 0.1; Co <0.1, 0.0; total 88.0, 97.8. This corresponds to (Ni3.12Hg0.17)Σ3.29As2.82(S3.03Se1.00)Σ4.03.
Possibly just non-stoichiometric Se-bearing gersdorffite.
